Description
Technical field
The utility model relates to continuous casting tundish, specifically belongs to a kind of and can detect online the continuous casting tundish that filling pipe end stops up.
Background technology
In the continuous casting steel machine production process of stopper rod flow control, it is to produce the common production problems of Ultra-low carbon steel grade such as low-carbon (LC) aluminum steel, Automobile Plate that continuous casting tundish upper nozzle stops up.Continuous casting filling pipe end stops up and there will be cast disruption, and it not only affects the Quality and yield of strand, and is unfavorable for the development and production of High Clean Steel Melts.Think and cause continuous casting tundish upper nozzle tamper to be obvious 3-tier architecture, be respectively from inside to outside heaped-up Al
2o
3weaker zone, netted Al
2o
3with compacted zone decarburized layer.Heaped-up Al wherein
2o
3mainly the Al being mingled with by absorption molten steel
2o
3and form, this is the main cause that filling pipe end stops up.Continuous casting tundish upper nozzle obstruction harm is very large, and important behaviour has: 1) cause cast to interrupt producing a large amount of tundish filling remaining liquid steels, in the service life of having reduced tundish, increased production cost.2) in the process producing at tamper, stopper stroke goes up, and crystallizer liquid level fluctuation of molten steel is excessive, easily produces adhesion bleed-out or excessive steel, and cc billet surface quality is difficult to ensure card.3) if tamper enters in molten steel after coming off, affect Molten Steel Cleanliness, easily form Large Inclusions, reduce Inner Quality of Billet.For reducing Al
2 o
3field trash, in the speed of gathering of filling pipe end inwall, is blown between argon gas and filling pipe end and immersion filling pipe end and carries out argon gas-sealed at continuous casting tundish upper nozzle, hinders Al in molten steel
2o
3deng field trash to the gathering of filling pipe end inwall with prevent the secondary oxidation of molten steel.But whether tundish upper nozzle stops up and plate between whether seal and to be difficult to check, cause the steady production of high-cleanness high-quality steel influenced.
Existing tundish argon-blowing device has the following disadvantages:
1, in the use procedure of continuous casting tundish, operative employee judges that between plate, the normal method of argon gas is at flow one regularly, and between plate, pressure approaching zero is that between plate, argon system is normal, cannot confirm like this to argon gas flexible pipe between plate and in use gas leakage of device at all.
2, in casting process, whether filling pipe end stops up operative employee does not have criterion, and a lot of situations are all adjust because of the argon flow amount of stopper (or slide plate) too large, liquid level argon gas blows out normal and has confused operative employee, after having poured into a mould two or three stove, filling pipe end forms dross, causes this steel circulation road top inner chamber distortion, originally smaller up argon gas is stopped and is constrained, and final filling pipe end stops up aggravation to be caused interrupting and stopping watering.
3, in the time of cannot not confirming in filling pipe end obstruction; operating personnel can strengthen stopper (or slide plate) argon flow amount conventionally; because stopping up, filling pipe end is blocked and oppressive Argon Bubble is slowly grown up and broken through and thisly disturbed normal eddy current just to cause the approximate regular fluctuation of mold liquid level when oppressive and up; tamper enters in molten steel after coming off simultaneously, reduces Inner Quality of Billet.
4, existing continuous casting tundish argon gas device can not be formulated a corresponding term of reference of Argon accurately for different steel grades, cast section and casting speed, cannot carry out the realization of formulation, enforcement and the unmanned cast of standardization Argon.
Utility model content

Feature of the present utility model: can be online by flow and the pressure condition of argon gas between simulation steel pouring process tundish upper nozzle argon gas and plate, sealing situation between the work of judgement continuous casting tundish upper nozzle and plate, for guaranteeing that producing High Clean Steel Melts provides condition, so that slab quality is stable, produce and meet user's requirement, and can improve strand qualification rate.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model;
In figure: 1-tundish body, 2-filling pipe end, 3-filling pipe end tunger tube, tunger tube between 4-plate, 5-filling pipe end argon blowing hole, argon blowing hole between 6-plate, 7-snap joint, 8-filling pipe end argon gas detector tube, argon gas detector tube between 9-plate, 10-argon gas house steward, 11-stop valve, argon gas stream scale is detected at 12-mouth of a river, 13-mouth of a river argon gas detected pressures table, detects argon gas stream scale between 14-plate, argon pressure table between 15-plate, 16-pressurizing valve, 17-sealing gasket.
The specific embodiment
Below in conjunction with accompanying drawing, be described further:
A kind of continuous casting tundish that can detect online filling pipe end obstruction, comprise between filling pipe end 2 on tundish body 1, tundish body 1, the filling pipe end tunger tube 3 on filling pipe end 2, plate argon blowing hole 6 between tunger tube 4, filling pipe end argon blowing hole 5, plate, it connects filling pipe end argon gas detector tubes 8 by snap joint 7 on filling pipe end tunger tube 3, between plate between plate on tunger tube 4 by snap joint 7 connecting plates between argon gas detector tube 9; Between filling pipe end argon gas detector tube 8 and plate, argon gas detector tube 9 is communicated with argon gas house steward 10 respectively; Stop valve 11 and pressurizing valve 16 are installed on argon gas house steward 10; The mouth of a river is installed on filling pipe end argon gas detector tube 8 and detects argon gas stream scale 12 and mouth of a river argon gas detected pressures table 13; Between plate, between argon gas detector tube 9 upper mounting plates, detecting argon pressure table 15 between argon gas stream scale 14 and plate.
At above-mentioned parts and the junction between parts, be provided with sealing gasket 17.
The scope of the argon flow amount that is passed into filling pipe end argon gas detector tube 8 that when normal according to filling pipe end, test detects and pressure limit be as basis for estimation, and at the mouth of a river, detect argon gas stream scale 12 and mouth of a river argon gas detected pressures table 13 and set; When being in operation, when if filling pipe end 2 occurs to stop up, flow can reduce, or the pressure principle that can increase, the argon flow amount that detects argon gas stream scale 12 when the mouth of a river reduces, or the pressure showing on the argon gas detected pressures table 13 of mouth of a river increase, all illustrate that filling pipe end 2 is blocked, should clear up in time or change.
According to argon gas between plate, pass into the scope of argon gas strength of argon gas detector tube 9 between plate and pressure limit the normal good seal in the situation that as basis for estimation, and at the mouth of a river between plate, detect argon pressure table 15 between argon gas stream scale 14 and plate and set; When between plate, seal badly, while having leakage, pressure can reduce, or the flow principle that can increase, increasing appears in the flow that detects argon gas stream scale 14 when between plate, or the appearance pressure decreased of argon pressure table 15 between plate, illustrate that between plate, argon gas exists leakage phenomenon, should take measures in time to recover normal.
This specific embodiment only exemplifies for the best, not the restricted enforcement to technical solutions of the utility model.
