摘　　要：针对中厚板热轧时出现的边裂缺陷,研究了其形成原因及控制方法。结果表明,铸坯表面的微裂纹和轧件的不均匀变形是边裂产生的主要原因,通过调整加热及轧制工艺参数、优化轧机配辊等措施可有效控制板材边裂缺陷的产生。The cause and control measures of edge crack in the roiling course of medium and heavy plate were investigated. The results showed that the main reasons of edge crack are micro crack on casting slab surface and the asymmetrical deformation of the piece. The edge crack of the plate can be controlled by adjusting the process parameters, optimizing rolls arrangement and so on.
