Reasons and treatment methods of billet stripping in continuous casting
Uneven cooling causes stripping.Check that the water jacket is uneven;Then check the two cold, the nozzle is not even spray cooling water, jet angle position is correct.
even two cold regions can be uniformly cooled, due to uneven thickness of shell, caused by the inconsistent temperature, the shell shrinkage is still uneven, and also there will be the development of. Therefore, the selection of unqualified mold is the main reason causing the removal. Secondly, the cooling effect of the two cooling zone can not be ignored.
The main reason for the stripping is that the slab is not uniformly cooled in the mold, which results in uneven thickness of the shell, which results in uneven shrinkage, which leads to the unevenness of the billet. If the mould outlet, two cold area is uneven, the shell support is not full, it will make breaking-off intensified;
