Summary of the invention:
The purpose of this utility model is to design provides a kind of rational in infrastructure, easy to make, lifting and service-strong metal shell and the long-life tundish clad that the anti-material of cast is composited, and makes its actual life more original steel-casting form improve 1～2 times.
For achieving the above object, the utility model is realized as follows: the surface structure form of every clad is by the plate shaped arch that changes into, adopt the steel plate of common material to be welded, concave surface welding " people " font harrow nail that adheres to anti-material at needs, anti-material is cast in the concave surface of arch, and anti-material has the radian same with original steel sheel, structurally guarantees its intensity.Anti-material is except that adopting conventional binder, and new clad has proposed strict demand to the quality of knotting layer own, and at the built-in steel fibre of knotting layer, has played good reinforcement reinforcement effect, makes the anti-material knotting layer that adheres to be difficult for monoblock and peels off.In order to guarantee to toast and gas permeability when being heated, on box hat and anti-material, be provided with the air-vent of diameter 5～20mm.On the convenience of operation, guaranteeing the ladle long nozzle operation freely, under the situation of roasting nozzle no-float, the opening in orifice, preheating gate and stopper hole is all reduced greatly, and the one-tenth enclosed type, not yielding after making clad be heated.High density " people " font harrow nail is set all around at anti-face and preheating gate, stopper hole simultaneously, makes anti-material knotting layer be easy to adhere to.Again pour into a mould new anti-material after can destroying after anti-material corrodes, and steel sheel can use repeatedly.
Effect of the present utility model:
Show that through use generally speaking, the new older clad life-span of tundish clad is enhanced about more than once.After anti-material damaged, new tundish clad steel construction distortion was little, and the anti-material of can the dismantling new anti-material of tiing a knot once more continues to use.Concerning continuous casting, the advantage applies of new tundish clad is aspect several: 1, ensuring under the prerequisite of the enough operating spaces of long nozzle operation, orifice, preheating gate, stopper hole are reduced and seal, heat insulation effect when making baking and cast improves greatly, to improving baking efficient, stable molten steel temperature in tundish plays better action.2, old clad peels off because of the iron scale that baking may occur the time, stops up the mouth of a river after falling into tundish, waters failure thereby cause opening, and adopts behind the new clad because towards the stamp mass of anti-material adhesion-tight of tundish, and failure is watered in opening of having avoided causing thus; Simultaneously, also removed under the high temperature the drop situation of tundish of iron scale has been confirmed cleaning, alleviated labour intensity.3, new clad good seal, the heat radiation of molten steel in the tundish can improve working environment of operating personnel when reducing cast.4, behind the new clad of employing, improved the tundish clad quantity that can have enough to meet the need, clad no longer becomes the bottleneck of restriction tundish preparation work rate.5, the area of the orifice of new clad and bypass preheating gate be old clad with the position 35% a little less than, in can alleviating greatly Baogang's water to the radiation intensity of ladle hydraulic cylinder, favourable to improving hydraulic cylinder life-span and production direct motion.
