Description
One, affiliated technical field
Baoshan Iron and Steel Group: Anshan iron and steel plant: Shoudu Iron and Steel Co: domestic continuous-cast blank production such as Wuhan Iron and Steel Plant, all be in the normal knot plug that low-temperature steel is cast, particulate electricity low temperature molten steel degree of supercooling do not tie plug, rescue that to cast be the breakthrough of zero, the lonely fine setting of electricity, the particulate electricity is transferred slightly.
Two, prior art
Liquidus curve zero degree, degree of superheat ratio must be modern sequence casting scientific theories just in time, the mechanical turning stress of correctness (alloy volume) that technology is used etc., the fundamental requirement of productivity, practical operation, real-world operation ability, the primary productive force of operating technology.
Most Urgent, without a stop, the rescue theory of low-temperature steel, being must wholely improving of degree of supercooling in fact, also is that latent heat forces than limit in the degree of supercooling, impel, speed-raising, static pressure increases, and real overall degree heats, to the greatest extent near the liquidus curve zero degree, the no timber Tibetan pyrogenic process of lighting stove, increasing of degree of supercooling becomes, the method at top speed of practical operation.Liquidus curve is sub-zero compels, and presses, and impels the coenosarc power that circle changes that produces, be to optimize to cast technology in fact, cast the practical operation method near the continuous casting of setting temperature, decide the power short-term training, the paste liquid state, the particulate electricity low-temperature steel that coenosarc power produces is not tied the plug sequence casting and is cast theory.
Three, Fa Ming purpose
Reduce steel mill's system temperature, cast, produce high-yield and high-efficiency, the primary productive force of continuous casting technology near setting temperature.
Four, Fa Ming content
When low temperature molten steel mouth of a river knot was filled in, the gas-liquid attitude latent heat of tundish was deep, and scope is bigger, at least hundreds of minute just can reach the mouth of a river knot plug attitude of agglutinated crystalline substance, be designated as the knot plug at the table normal low temp mouth of a river, essence endosome essence is knot plug just, the casting continuously of particulate electricity recurrence vigor effect.
(1) molten steel is quiet is poly-, and moving is gas, also is power, and hydrostatic freezes, the hypodynamic basic actual property of static pressure.
(2) mouth of a river of little air-flow liquid state knot plug is the slag that gas emits sinking, the solid not network body of melt fiber, and certain pressure of putting local syringe needle hydrojet lacks, and the mouth of a river knot of real poor rotatory force is filled in.
(3) click, folding, tension force, revolving force, round as a ball power, change power continuously, a bit discontinuity is not followed and is not stopped etc., or the like.There is pressure just dynamic, evenly moving commentaries on classics power, active power liquid state, the generation of instinct.
(4) mud can push away mud, is above Most Urgent in fact, robs must raising speed of fast 0.2 second without a stop, be not tie at the formation crystalline substance, the liquid state in 0.2 second of dynamic stuffy degree is in liquid-solid two-phase and deposits state, rotation, the circle rotatory force does not stop to wait state, little gas molten steel attitude of circulation stream power.
(5) the atomic atomic slight electricity of casting with " physical force " and " chemical force " atom and molecule (trembling) waits that interacting rubs operates generation, reached the gas-liquid attitude vigor of coming back to life, three kinds of liquid state of flat attitude stream power, its brand-new critical surface is arranged, and vigor low temperature is carried fast normal continuous casting and is cast.
(6) beginning of the unable molten steel of beating of ant disco, also be that year-round work contract system is decided the beginning that power reality must be operated in advance, force, the real speed-raising heats, form the ant holder and shoulder the coenosarc power generation of bone, be latent heat speed ratio in the degree of supercooling, the actual flowability of trembling the commentaries on classics power generation of flowing of jumping is not tied the plug molten steel yet.Three QQQ in the bag whole airbag [O] especially, and big ballonet comprehensively pushes dynamics Rolling liquid state, also is the realization performance of the sticking body of certain soft or hard fibroid among three Q, the molten steel of normal Liquid Flow and knot plug never, little power of mobilization force produces once more.
(7) the no timber Tibetan pyrogenic process of lighting stove is the inherent density of low temperature molten steel in fact, and with mouth of a river proportion, far and near density is crossed and spent timeliness with fixed attention, the fastest speed-raising, and homogeneous forming core reality is impelled method at top speed, and is evenly synthetic.
(8) whole [O] also equals Q, and gas explodes than meeting greater than Q, go out [O], the easy bleed-out of high left Q waters otherwise the knot plug is disconnected, the above zero some degree of liquidus curve (deciding by steel grade) are real normally to be cast for middle Q stability, also is equilibrium between yin and yang degree ratio, the productivity of actual dynamics warm in nature.
(9) the dynamic urgent pyrogene [O] of molten steel gas-liquid attitude nature heat release agglutinated.
Molten steel is quiet to be poly-, and moving is gas, flows capable, fine fine, sticking change rare, whole quiet poly-, moving gas, the table agglutinated connects, and interior tight pupa pine is shown little contraction, interior big little electricity, horizontal sticking hundred jin, perpendicular stream is very heavy, static pressure ask ratio, big or small cystozooid, Q dashes facilitating of [O] body, muzzle is raised the key effect that one-inch waters method for making, and sufficient driving force is asked force rate greatly.
(10) in the molten steel, the one-tenth of gas exists, also be particulate cast basic, also be the basic of former reason of the inherent spray blast of molten steel, also be two tendency high-temperature steels and low-temperature steel, two extreme coincideing.
The agglutinated low temperature gas-liquid attitude of paste molten steel is that heat dive to improve in the liquidus curve subzero degree of supercooling, and what strand stumbled that round commentaries on classics power produces rare stream power does not stop to wait rotation.
Pneumatic come-up, gas sinks less, the round turn of tidal stream power of fiber calculus impel into the gas-liquid bag, [O] blows the actual property of the power of foreign bubble especially exactly, produces internal pressure, balloon is being urged gas without a stop also always, the inherent cold and hot temperature difference is takeed on friction mutually, holds in both hands and revolves the mouth of a river, then do not fill in fixed attention, be same philosophic theory, the unity of opposites is the basic rule in universe.
(11) smelting of converter, add extra quality etc., rollability between fusion, the molten steel attitude is collaborated oxygen blast, the rollability after the rotation uniformly, the body degree molten steel of very all uniting is the stream power of normal flat attitude copper liquid, and (do not comprise alloy volume what) produces this liquid flow power, whether the smelting of above converter is not understood at all, the particulate electricity is cast do not tie plug be behind converter tapping to the strand stage, whether needn't, really in the operating physical force ratio, the rotatory force ratio, actual is the force rate of scientific and technical primary productive force.The equal factor of real-turn of spray blast in the converter would not take place.
(12) three Q in above [O], the left, center, right of every Q equal the actual magnification of nine Q all basic explanation solved the big bleed-out of gas, the fibroid disconnection, on the contrary the gas brief summary is also, and fibroid is coagulated thick, the fiber blending is even, liquidus curve, and the reality of middle Q degree is normally cast, each comrade can both operate and slap certificate, the gas-liquid attitude of low temperature molten steel, commentaries on classics power do not stop can normally cast yet, and reality is said well, there is not low-temperature steel knot plug, the essence of continuous casting definition must be pointed out, in advance the operation under the consciousness, generation is active power, the very physical degree of " physical force " and " chemical force ", ant coenosarc, reactiveness, the bone circle is shouldered in holder changes the generation of strength, continuous casting is really normally cast, optimized continuous casting process, near normally casting of setting temperature, and matter material density height, the quality continuous casting of good high-yield and high-efficiency is again cast.
Five, Fa Ming effect
China's output of steel world rankings first, national steel output was 386,545,030,000 tons in 2000, calendar year 2001 increases to be estimated at 18,000 ten thousand tons, the particulate electricity method at top speed that raises speed, reduce steel mill's system temperature, as the 1/5 strand speed that speeds casts, and increases production the about 700 hundred million tons of left and right sides output of steels every year at least, other or the like.In in the bag [O] among three Q, the left, center, right of right Q, atomic point, speed ratio is decided power, actual location is decided the essential formation of power, and the key meaning of effect must be, sail against the current, not all rightly then move back, circle changes blending, and power fibroid packing network body gas-liquid produces continuous followability, be that the acute wood of rope is disconnected more, the engineering that dripping water wears through rock.Mud can push away mud, and the molten steel of pasty state liquid can push-jump mobilization force be basic crucial actual effect, and a face of making peace is most urgent, the real effect of practical operation generation microsecond without a stop, and operating technology is decided the primary productive force of power.
Six, embodiment
Because the work in nearly ten years is conscientious, have at least hundreds of thousands time beautiful eye to wear and see molten steel, one order is revealed the exact details, several thousand task platform high and lows watch open type Ding Jing molten steel that flow out at the mouth of a river beam of taking back or take over how can form and produce towards copper wall and water jet actual cause, through again and again thinking, explore especially, think hard, several egersis it (liquid) and actual argument have drawn a cover row and have known that effective particulate low-temperature steel do not tie plug operation theory, more than are basic enforcement.
On March 27th, 2000, with writing all views of having made molten steel in 4-5 month, in fact reasoning is exactly do not tie plug ultimate, the implementation and operation way, such as muddy, circle, suitable, force method, it is precious hard-earned or the like that 1+3-3=0, four priestlings hold up wood to water the gold point of method for making, the real meaning of carrying of comprehensive theory.Once certain little continuous casting one machine three stream is tied plug together, remaining 8-9 ton low temperature molten steel (14.5 millimeters at the Ding Jing mouth of a river will be wrapped greatly, 8 tons of middle containing amounts), I operated the approximately also surplus steel of 7-8 ton low temperature of a big bag of machine at that time, this has been watered, about about 9 minutes, and then water the surplus steel of its 8-9 ton and then watered, fill in to connect from its knot and water at that time, have very many clocks at least, molten steel is real to have glued one one-tenth again, the full knot plug of the former three streams, the latter locates normally to cast completely, so unskilful at ordinary times chance contrast, its three stream knot plug, I connect and have watered then, and having only can prove more that this time I have used the particulate electricity, three Q among [O] that comes back to life again, right Q limit, hundreds of minute is frozen into mouth of a river knot plug shape, shows no sign of the least bit and stops etc., and it is existing that vigor becomes, consciousness is magnified the power operation in advance, advance to go out for a short time greatly, show in little greatly, cold thick heat is thin, the cover stream of the network fibres body of fibroid and fiber calculus, be crucial law, pure rescue, low again low-temperature steel just can not tied plug, unquestionable, the size of the circle rotatory force continuously key of commentaries on classics power is the most important, and real work has proved, three Q left, center, rights in [O], three kinds of right Q have its brand-new liquid state, and it is slippery liquid along logical efficient grain slightly that circle changes.
Ending:
The gas of no type increases or increases little in balloon, has certain gas to hike up naturally than balloon, locates internal and external equilibrium, the free interior turn of tidal stream of interior gas is moving, can't arrest, and more difficult right-falling stroke does not live and regains, have only pin gas leakage point, just can follow along the gas that comes out, inherent pressure is out that the size on year-on-year basis of gas is the same.
Ladle, tundish [O] is under specific situation, produce gas and lift situation, roof fall spray blast, inherent pupa is moving, coenosarc power produces, and rod revolves the mouth of a river, intrinsic pressure, flow, stuffy degree not between the crystalline substance of section do not tie, also arrest incessantly, that flees is dynamic, and balloon must be inflated, and middle bag three Q must become [O], static pressure forces, and impels, Most Urgent without a stop also, the commentaries on classics power and the operation of pressure and power basically form on year-on-year basis, the particulate electricity of coming back to life will never temporarily be tied plug, can not say well that at low temperature knot plug should use in advance, effect produces, simple operations, deep implication is decided the essential of power, various combined stresses, the practical operation of safety in production power.What solve is that in the middle bag, gas-liquid pressure and pulling rate get final product than occurring on computer screen surely, optimize and cast technology, reduce steel mill's system temperature, cast high-yield and high-efficiency near setting temperature, at least can speed 1/5 low-alloy steel strand pulling rate, 700 hundred million tons of left and right sides output of steels of the annual volume increase in the pre-estimation whole nation, the acute wood of rope is disconnected especially, the engineering that dripping water wears through rock, easy course, zero beginning.
The slight slippery property of particulate electricity is not coagulated degree, the gas molten steel of all nicely rounded turn of tidal stream power of fusion, and both warm low, matter is close again, and safety is put forward the actual again conscientiously primary productive force of fast advanced technology and is about to produce certainly.
Annotate 1.: atomic slight, the particulate electricity is the liquidus curve subzero, middle bag is estimated correctness between low zero following 18 ℃, also be in [O] among three Q, right Q operation enforcement, the left, center, right, every grade as 6 is spent ultimate ratios is each pre-preceding operation of deciding power, be that safe low temperature molten steel is normally cast, 1532 ℃ of liquidus curve zero degrees, 7 ℃ of the degrees of superheat belong to positive normal temperature dynamics continuous casting and cast, never ask the particulate electricity to produce, under normal static pressure, cast speed ratio, its easy bleed-out, should its near gas molten steel of liquidus curve zero degree, be not to carry fast particulate electricity to come back to life and carry fast continuous casting and normally cast.
Annotate 2.: as the fibrous not melt of single molten steel, little point, the calculus of network gonosome, knot is separated, and knot looses, and the knot pine is carried down, and what the tangible molten steel mobilization force that produces really do not prove again, for normal gas-liquid attitude low temperature is cast.Most urgent, the foreign bubble rescue of blowing is without a stop cast, must be to produce rub whole gas that the extruding of big or small cystozooid produces the gas jumping of " physical force " the alternate collision of coming back to life to emit the particulate of dynamics with " chemical force ", ant disco coenosarc power continuous casting is carried soon and normally being cast, must be evenly not synthetic, very little electricity be cast.
In the molten steel, the pressure of gas collection draws in, and expansion forces, and promotes to produce the stream power of the sticking disconnection of fibroid, unhitches, and separates and takes, and whole trembles slightly, produces the productivity of particulate electricity and mobilization force.Three Q in [O], real also is three circles, the circle tumbler is moving, that pushes dynamically in mutual rotation, rubs and flows the gas molten steel attitude of stress, and the slight particle of continuous casting low temperature molten steel is normally cast, be that the particulate electricity reduces steel mill's system temperature, optimizing continuous casting process, cast near setting temperature, is the primary productive force of advanced technology.
