通过对鞍钢中板厂中板分层情况的跟踪调查以及对典型样品的检验分析，认为中板分层的主要原因是由钢锭中的缩孔或缩孔残余引起的，而轧钢厂的生产工艺又进一步扩大了分层面积。据此，提出了减少中板分层的具体措施和建议。
Through the follow-up investigation of the slab stratification in the mid-plate factory of Ansteel and the inspection and analysis of the typical samples, it is considered that the main reason of delamination in the mid-slab is caused by the shrinkage cavity or shrinkage cavity in the slab, while the production technology of the rolling mill Further expanded the stratification area. Accordingly, put forward to reduce the board of the concrete measures and recommendations.
