Description
The utility model belongs to metallurgical test and microcomputer display technique field.
At present, domestic method for making steel no matter be pneumatic steelmaking, electric furnace steel making, or method for making steel such as open hearth steelmaking, accomplish that each stove output of steel equates in a kind of method for making steel, and every in other words stove molten steel amount is all poured into a mould the steel ingot of identical number, is very difficult.This is because because raw material quality and specification that each stove uses, control of quantity meter and appointed condition are not quite similar, even under the same working condition, because the different smelting operations of concrete condition at that time, thermal regulation and pouring operation also are discrepant, therefore say and will accomplish that each stove output of steel is equal fully, the steel ingot that every in other words stove molten steel amount is all poured into a mould identical number is difficult to apply.In order to improve Ingot Surface Quality, steel ingot particularly rimmed ingot generally is to adopt the method cast of making a bet, that is to say the method for making a bet be at one time in, the molten steel in the ladle, by feed trumpet, pour into a mould several (being generally 4～8) steel ingots on the ladle barrow from top to bottom.If the control of molten steel weight meter is inaccurate in the ladle, the short ingot in the time of will causing pouring into a mould forms waste product.This is because because steel ingot must have certain enough length.To adapt to the rolling needs of steel ingot.If ladle at one time in cast during several steel ingots, because the meter control is inaccurate, in the bucket the inenough steel ingots of molten steel amount water fluence the time, so just will inevitably produce the deficiency of several ingot steel casting amounts and become short ingot waste product, all that has been achieved is spoiled thereby make the work of each operation of steelmaking process.Therefore, do to measure ladle liquid level and weight thereof well, to improving business economic benefit and technical economical index, significant.
Current, domestic measurement and the method for judging molten steel amount in the ladle mainly contain electronic scale weighing, iron staff measurement and range estimation and estimate three kinds.The projection electronic weighing method can only can't be differentiated the weight separately of barrel interior molten steel and slag to the tolerance of whole ladle, thereby it is only applicable to the effectively pouring operation of the converter steel of shelves slag; The iron staff mensuration now only is used for small-sized ladle and pours into a mould small-sized steel ingot, and measuring operation is numerous and diverse, and the high dust of environment temperature is big, and iron staff also will stop certain hour in molten steel, causes prolong the duration of pouring, annotates defectives such as ingot platform operating rate reduction; Ocular estimate is everlasting and is used when big-and-middle-sized ladle is poured into a mould big-and-middle-sized steel ingot, promptly observe interior thickness of slag layer of ladle and molten steel and molten slag erosion look the brick state and judge a barrel interior molten steel amount, but shortcoming is a lot of, as tie a knot bucket when looking the brick wall dross, sinter thickness and molten molten steel face are difficult to differentiate, sometimes melting steel amount is few in the bucket, the base plate bleed-out of in casting process, making a bet, or water high normal variant etc. because of the uneven steel ingot of railway, half ingot and last notes ingot are increased, cause its steel rolling blank surface defects also can increase with declaring useless and changing the quantity of rolling for seconds.
Abroad, its main cause of electrode measurement method that has of measuring ladle molten steel Weight apparatus at present is that constant pressure source serial connection current relay carries out level gaging.This when major loop constant voltage series process is being measured, need regulate the resolution ratio of this stove steel and slag and measure steel grade only be middle charcoal steel and low alloy steel, the resolution ratio claimed range of molten steel and slag is wide, and above-mentioned steel grade in addition is difficult to accurate mensuration.
The purpose of this utility model is to provide the measurement mechanism of slag interface in a kind of ladle, can differentiate the various different slag interfaces of smelting steel grades effectively, and show that rapidly a last molten steel should water steel ingot number and surplus in the bucket.
The utility model has and improves the steel ingot rate of making a bet, and improves product quality, reduces short ingot waste product, improves recovery rate of iron and saves advantage such as ingot mould consumption.
Fig. 1 is ladle level gaging and weight display device process flow diagram thereof.
This device is by ladle (1), electrode cable hole (2), bucket outer conductor (3), measuring instrument connects lead (4), slide gate nozzle oil cylinder lead (5), iron wire (6), voltage stabilizer (7), level instrument (8), microcomputer (9), printer plotter (10), cassette recorder (11), monochrome monitor (12), electric whistle (13), instrument box (14), power switch (15), supply socket (16), ingot mould (17), feed trumpet (18), floor (19), ladle barrow (20), and ingot casting platform (21) is formed.
When ladle is laid bricks, imbed lining brick in by actual requirement electrode after, lead is introduced outside the bucket, and is tightened connection with bucket outer conductor one end, add insulation protection.So-called actual requirement is meant that promptly electrode imbeds the appropriate location of barrel liner tile, should be that the liquid level position of one group of steel ingot is advisable with molten steel volume in this barrel.Make a bet and turn on the power switch (15) when watering the steel operation and insert supply socket (16), the socket that bucket outer conductor (3) is connected lead (4) with measuring instrument connects, measure lead then with slide gate nozzle oil cylinder lead (5) operation, put into iron wire (6) in the ingot mould in advance.In the pouring operation process, when the contact of the electrode in idle brick slag, because molten steel is different with molten slag electric conductivity, it is the different principle of resistance sizes, electric whistle (13) is promptly reported to the police, annotate the steel worker and promptly take out iron wire in the mould in view of the above, iron wire is watered high size input microcomputer (9), the quantity of the steel ingot of determining at last to make a bet.It is to provide comparatively suitable power supply to level instrument that level instrument (8) adopts constant current parallel-current relay method voltage stabilizer (7), and microcomputer (9) is to carry out multiple arithmetic operation according to the instruction that gives.Printer plotter (10) and the supporting use of microcomputer are printed the instruction and the display digit that give get off.After having a power failure, the content of chunk just can lose in the microcomputer, and cassette recorder (11) belongs to the peripheral reservoir of storing the chunk content.Monochrome monitor (12) and the supporting use of microcomputer show that the ladle molten steel should water steel ingot number and residue molten steel weight at last.
