Description
Technical field
This utility model belongs to the improvement of steel mill sheet billet continuous casting operation slab attemperator structure, particularly a kind of alloy
Steel continuous casting steel billet slow cooling attemperator.
Background technology
Current most of steel alloy, due to alloys producing, undergoes phase transition in high temperature cooling process, and structural stress is sent out
Changing and cause casting billet surface and inside to crack.Such as, martensitic stain less steel, when being cooled to 200～300 DEG C, by
In producing martensitic phase transformation, cause volumetric expansion, cause structural stress to form the fragility of strand.For another example bearing steel, by slow
Cold energy is enough substantially reduced structural stress and the thermal stress that cooling procedure produces, it is possible to prevent the generation of white point.So ordinary circumstance
All hang in after lower alloy steel continuous casting strand ejection in the burial pit of setting.
The subject matter that existence deposited by high temperature slab is as follows:
1, due to high temperature, staff cannot be close, and impact checks, worker's labor condition is poor.
2, personnel cannot be near observing, and steel slab surface defect cannot check, and affects the later stage and sends out steel to steel rolling.
3, high temperature slab relies on radiation to cool down with cross-ventilation, and cooling rate is uncontrollable, controls continuous casting billet inside
Reason brings adverse effect.
Utility model content
The purpose of this utility model is to provide a kind of alloy steel continuous casting slab slow cooling attemperator, and it is rational in infrastructure, can
To control the rate of cooling of continuous casting billet, it is possible to prevent the generation of white point, improve continuous casting billet quality, use process simple, movement side
Just, the labor intensity of operator can be reduced.
The purpose of this utility model is achieved in that a kind of alloy steel continuous casting slab slow cooling attemperator, including alloy
Steel continuous casting billet, its two sides of door shape excavation support being made up of shaped steel and end face are respectively and fixedly connected with two side that steel plate constitutes and
Roof, on the inwall of two side and roof respectively by uniform nail thorn affixed refractory masses constitute the insulation of door shape and protect
Cover, high-temperature continuous casting blank leaves in a shape heat-preservation guard shield.
Main improvement content of the present utility model is as follows:
Using structure steel fabrication slab attemperator, top is added a cover, and inside builds refractory material by laying bricks or stones, plays function of heat insulation,
So that slab Slow cooling.
Main improvement effect:
1, use process simple, conveniently moving, it is substantially reduced labor intensity of operating staff.
2, alleviate heat radiation, improve the labor condition of worker, it is ensured that personal security, it is achieved that essenceization is kept the safety in production.
3, the rate of cooling of continuous casting billet can be controlled, be conducive to improving the internal soundness of continuous casting billet.
This utility model is rational in infrastructure, it is achieved that control the rate of cooling of continuous casting billet, it is possible to prevent the generation of white point, improves
Continuous casting billet quality, uses process simple, and conveniently moving reduces the labor intensity of operator.
Accompanying drawing explanation
Being further described this utility model below in conjunction with accompanying drawing, Fig. 1 is the signal of this utility model stereochemical structure
Figure.
Detailed description of the invention
A kind of alloy steel continuous casting slab slow cooling attemperator, as it is shown in figure 1, include alloy steel continuous casting base 4, is made up of shaped steel
Its two sides of door shape excavation support 1 and end face on be respectively and fixedly connected with steel plate constitute two side 2 and roof 3, two side 2 He
On the inwall of roof 3 respectively by uniform nail thorn affixed refractory masses constitute door shape heat-preservation guard shield, high-temperature continuous casting blank 4 is deposited
It is placed in a shape heat-preservation guard shield.One end of door shape heat-preservation guard shield is closed by heat insulation wall.
Claims (2)
1. an alloy steel continuous casting slab slow cooling attemperator, including alloy steel continuous casting base (4), is characterized in that: be made up of shaped steel
Door shape excavation support (1) its two sides and end face on be respectively and fixedly connected with steel plate constitute two side (2) and roof (3), two
On the inwall of sidewall (2) and roof (3) respectively by uniform nail thorn affixed refractory masses constitute door shape heat-preservation guard shield, high
Temperature continuous casting billet (4) leaves in a shape heat-preservation guard shield.
Alloy steel continuous casting slab slow cooling attemperator the most according to claim 1, is characterized in that: the one of door shape heat-preservation guard shield
End is closed by heat insulation wall.
