Q550D 钢板强度同板差大的原因分析及改进措施

摘要

The article studies and analyzes the problem of big intra - plate strength difference on Q550D steel plate,discusses the causes of such difference from various respects of plate surface finish,flatness,mode of heat trans-fer and the parameters of MULPIC system,and puts forward improvement measures,which receives good results.%围绕 Q550D 钢板的强度同板差大这一问题展开研究分析，从钢板表面光洁度、平直度、传热方式和 MULPIC 系统参数等方面探讨了强度同板差大的原因，提出了改进措施，取得了良好效果。
