Description
Technical field
The utility model belongs to casting fused mass field of containers, particularly relates to a kind of anti-spilled continuous casting production.
Background technology
Continuous casting production is important metallurgical technology equipment, it is not only distribution, ensures the buffer of molten steel direct casting, it is still removed non-metallic inclusion, evenly liquid steel temperature, prevents slag from entering the key equipment of the guarantee slab qualities such as crystallizer, and its metallurgical effect directly affects the quality of strand.Molten steel enters in tundish from the inlet of tundish, and then flow in crystallizer from the liquid outlet of tundish pass in and out next step operation, thus realize continuously operate.And in actual mechanical process, need the amount in strict control inflow tundish.When the equipment controlling molten steel flow breaks down, then the amount in tundish may be caused too much, and molten steel overflows from the inlet of tundish, causes security incident.
So, be badly in need of a kind of when controlling the equipment of molten steel flow and breaking down, the device that molten steel overflows from the inlet of tundish body can be avoided.
Utility model content
The purpose of this utility model is providing a kind of anti-spilled continuous casting production, overflows in tundish to avoid molten steel.
In order to achieve the above object, base case of the present utility model is: anti-spilled continuous casting production, comprise tundish body, wherein, also comprise slide and baffle plate, the sidewall of described tundish body is provided with overfall, the upper end thereof of described baffle plate on the sidewall of tundish body, and can close overfall, and described slide is obliquely installed, it is high-end is fixed on tundish body, and slide is positioned at immediately below baffle plate.
The principle of this base case is: break down when controlling the equipment of molten steel flow, when the amount of the intrinsic molten iron of tundish there was not overfall, then illustrates that molten steel is excessive.Now, molten steel promotes flapper, and unnecessary molten steel flows out from overfall, and flow to other places by slide and reclaim.When the intrinsic molten steel of tundish did not have overfall, then now molten steel was inexcessive, and baffle plate under gravity, returns to home position, was closed by overfall.
The beneficial effect of this base case is: baffle plate can block overfall, avoids air to enter in tundish, makes the state that tundish body remains airtight, reduces the thermal loss in tundish.Compared with traditional continuous casting production, overfall then can be opened automatically in the position that molten steel exceedes overfall, when molten steel does not exceed the position of overfall, overfall then can be made to be in closed condition all the time, without the need to artificial guard, effectively avoid molten steel to overflow from the inlet of tundish, decrease the generation of security incident.
Scheme two: based on this, scheme is preferred, and the lower end of described baffle plate is connected with pulling block by rope, the fusing point of described rope is 200-1000 DEG C.In correct situation, pulling block, under the effect of self gravitation, down holds rope, makes baffle plate be in vertical state all the time, prevents flapper, guarantee the sealing of overfall.When molten steel did not have overfall, molten steel flowed out, and melted by rope, baffle plate loses the pulling force pulled open, can the rotation of greater angle, made the opening of overfall larger, guaranteed that excessive molten steel all can overflow in time.
Scheme three: this is the preferred of scheme two, described pulling block is flame-proof sphere, and when rope fuses, the pulling block of spheroid is easier to be skidded off from slide, avoids pulling block to be stuck in slide.
Scheme four: based on this, scheme is preferred, described overfall is the overfall of inverted trapezoidal.The overfall of this design, when molten steel excessive in tundish is more, then the opening of overfall is then gradually large, and the amount that molten steel is discharged is then larger.
Scheme five: based on this, scheme is preferred, the inwall of described slide is refractory masses, and outer wall is provided with heat-insulation layer.Refractory masses then can avoid molten steel to be melted by slide, and heat-insulation layer can prevent molten steel from solidifying in slide, avoids molten steel to block slide.
Scheme six: this is the preferred of scheme four, described refractory masses is silica refractory layer, and outer wall is alumina silicate fiber felt.Silica refractory layer has good fire resistance, and alumina silicate fiber felt then has good heat-insulating property.
