摘　　要：分析了中板轧制生产中坯料设计需综合考虑影响成材率、生产率的各个因素,如轧制方式、展宽比和压缩比的确定,设备尺寸的限制条件,剪切余量及加热烧损等,然后结合实际生产中产品订单和不同的成品规格来设计中板轧制过程的坯料尺寸。按此方法,唐钢第一钢轧厂减少了Q235B单定尺板非正品率7%,提高了Q345A混合板成材率1.25%,提高了GL-A船板双定尺板成材率0.46%。The influence factors on yield and productivity during slab design for medium plate production should be taken into account, such as rolling technology, spread rate, compression rate, dimension condition of machine, shearing residue and burning loss, etc. Mean while, it should combined the indents and finishing products specification. During the practical production of No. 1 Mill of Tangshan Iron ＆ Steel Co. ,Ltd, ,the yield can be increased 1.25% of Q345A plate and 0.46% of GL-A hull plate.
