摘　　要：中厚板表面麻点是钢板表面质量好坏的主要影响因素之一,如何有效减少钢板表面麻点,需要从缺陷源头着手并结合轧制实际展开分析、研究。针对中厚板表面麻点产生的原因,通过采取加强加热炉温度、高压水除鳞控制,同时优化支承辊装配参数、控制矫直过程等措施,有效地减少了表面麻点缺陷的产生,提升了钢板表面质量。The surface pittings of medium plate is one of the major factors affecting plate surface quality.The analysis and research need to be performed from the defect origin in production in combination with rolling practice.According to the formation causes of the surface pittings on medium plate,measures are taken to strengthen the controls of reheating temperature,primary descaling and mill stand descaling,optimize the backup roll fitting parameters and leveling process control etc.,the formation of surface pittings on medium plate is efficiently reduced,the surface quality of steel plate is improved.
