If the casting speed is not steady, what will happen to the billet?
First of all, the probability of slag circle, dimple, crack and blowhole on the surface of the billet will increase, and the slag inclusion in the slag will increase, which will affect the internal and surface quality of the slab.
The instability of the casting speed leads to the unstable surface of the mould and increases the probability of slag entrapment in the mold.
Secondly, the speed of cutting is unstable, and the cut rate will be reduced.
