Mouth enters into crystallizer, then is cooled into strand through casting machine fan-shaped section.
At present, the steel mill that domestic and international sheet material produces, major part is that this IF steel is Ultra-low carbon based on the production of automobile IF steel
Aluminum killed steel, the deoxidation and alloying of molten steel is completed with aluminum, and its deoxidation products is aluminium sesquioxide, tiny three oxidations
Two aluminum have certain amount in steel and discharge it is impossible to float completely, and in molten steel continuous casting, tiny aluminium sesquioxide can bond
Blocking is formed on ladle canal wall, have still stays in formation steel inclusion in steel, deteriorates steel quality.
Utility model content
There is provided a kind of preferable purification of molten steel facility in place of this utility model is intended to overcome the deficiencies in the prior art, can replace
The slag weir that has for height former in tundish, dam function, catch and absorption molten steel in tiny aluminium sesquioxide, slow down stream steel
Channel blockage, improves the continuous casting production purification of molten steel device of the quality of steel.
For solving above-mentioned technical problem, this utility model is realized in：
Continuous casting production purification of molten steel device, it includes the casing of resistance to material；The first side wall pushing off the slag layer in the described casing of resistance to material
And the first hole type ladle canal and the second hole type ladle canal are respectively equipped with successively on second sidewall pushing off the slag layer；Described resistance to
It is provided with resistance to material in material casing and purify component.
As a kind of preferred version, the casing of resistance to material described in the utility model can adopt trapezium structure.
Further, the axis of the first hole type ladle canal described in the utility model and the second hole type ladle canal
It is in be crisscross arranged.
Further, resistance to material described in the utility model purifies component and can adopt spherical structure.
Further, the first hole type ladle canal described in the utility model and the second hole type ladle canal are circular stream
Steel passage.
Further, this utility model is provided with mud hole in described resistance to material casing top.
Further, resistance to material described in the utility model purifies component is in that single or multiple lift arranges.
In continuous casting production, it is provided with purification of molten steel device, pour during molten steel during steel flows through purification of molten steel device, purification of molten steel
Device can catch and adsorb tiny aluminium sesquioxide in molten steel, reached the purpose of purification of molten steel, improve the quality of steel.
During the purified device of this utility model steel flow, because the steel outlet hole on barricade before and after depurator is unsymmetrical arrangement
, change the flow direction of steel stream, make large inclusionses in steel collide on barricade to float discharge, serve cleared
Change the effect of large inclusionses.Simultaneously when molten steel flows through continuous casting production purification of molten steel device, because of the material of scavenging material
Basically identical with the composition of steel inclusion, tiny field trash in molten steel（Mainly based on aluminium sesquioxide）Bonding can be adsorbed
To the surface of spherical fireproof material, reach and removed the effect purifying fine foreign matter in molten steel, because scavenging material is spherical setting
Meter, specific surface area maximizes, make molten steel and spherical scavenging material carried out sufficient contact, scavenging material surface adsorption bonding
Fine foreign matter at most, substantially purified molten steel, the degree of purity of molten steel greatly improves, and the quality of steel has obtained significantly
Improve.

Specific embodiment
As illustrated, continuous casting production purification of molten steel device, it includes the casing of resistance to material 1；In the described casing of resistance to material 1 first
It is respectively equipped with the first hole type ladle canal 301 and the second hole successively on side wall pushing off the slag layer 201 and second sidewall pushing off the slag layer 202
Shape ladle canal 302；It is provided with resistance to material and purify component 4 in the described casing of resistance to material 1.
In specific design, the casing of resistance to material 1 described in the utility model can adopt trapezium structure.Shown in Figure 2, this practicality
The axis of new described first hole type ladle canal 301 and the second hole type ladle canal 302 is in be crisscross arranged.Referring to figure
Shown in 2, resistance to material described in the utility model purifies component 4 and can adopt spherical structure.Shown in Figure 1, described in the utility model
