摘　　要：通过优化分配四辊粗轧机和四辊精轧机的道次与压下量,达到了控制板形凸度平直度的目的,优化后的切边、切头数量分别下降至40～100mm和200～400mm;同时控制钢板剪切精度,并采取“先断开,再切边”的剪切方式应对“镰刀弯”。由此,中厚板成材率由91.5%～93%提高至92.5%～94.5%。By distributing the pass and reduction of four roughing mill and four high finishing mill optimally, the objective of controlling profile-crown-flatness is reached and the side crops and crop ends of produced plates are 40- 100mm and 200-400mm separately. At the same time, by controlling shear precision and adopting the sheafing mede of ＂first disconnecting then cutting edges＂ against ＂camber＂. Therefore the roiling yield of the plains is increased from 91.5% -93% to 92.5%-94.5%.
