At present, the tundish cover that most domestic steel mill uses all uses steel construction as support frame, pours one layer of refractory material towards the side of molten steel.But, due to clad aborning by the long-term baking of high-temperature molten steel, deformation and scaling loss inevitably occurring, causes resistance to material constantly to fracture and flake off, fracturing and flaking off in entrance molten steel of resistance to material pollutes molten steel, has a strong impact on slab quality.At the tundish using stopper control to control, the resistance to material come off is attached to filling pipe end position can cause the adjustment malfunction of stopper.After resistance to material damages, the protection to clad weakens, and steel construction scaling loss is more serious, resistance to material can be made again damaged more serious with come off, vicious cycle.It addition, the tundish cover of off-line by the condition of high temperature to low temperature, also can make resistance to material cracking and damaged.Above-mentioned situation be steel construction add resistance to material structure tundish cover self be difficult to overcome.
Summary of the invention
For the problems referred to above, the invention provides a kind of Novel tundish cover of continuous casting tundish, both solved clad life-span relatively low problem, turn avoid resistance to material and come off and pollute the situation of molten steel and occur.
For reaching above-mentioned purpose, the scheme that the present invention takes is: a kind of Novel tundish cover of continuous casting tundish, including middle cover and the side cover being positioned at the described middle cover left and right sides, described middle cover and both sides cover and are provided with stopper hole and baking hole, described middle cover and side cover are integrally cast by refractory steel respectively, described middle cover and side cover upper, the most all it is installed with reinforcement, middle cover and two side covers are symmetrical respectively about tundish axis, mutually symmetrical structure below the above and middle cover of middle cover, mutually symmetrical structure below the above and side cover of side cover, middle cover upper and lower surface is used interchangeably, left, right cap is also used interchangeably.
As optimization, described reinforcement uses groined type arrangement, on the premise of ensureing middle cover and side cover intensity, alleviates clad own wt.
As optimization, the periphery in described stopper hole and baking hole is installed with arc gusset, it is ensured that the clad intensity at stopper hole and baking hole.
As optimization, before and after described middle cover and side cover, side is provided with hanger, it is simple to the lifting of clad and upset.
