我国小型轧机生产一般要求产量高,产品规格品种较多,因此合理而且可靠的坯料供应对轧机的正常生产影响很大。目前除鞍钢、首钢等初轧供料手段较完善的生产厂家使用90～100mm方坯外,绝大多数小型轧机使用60mm左右的小方坯。近几年,由于小方坯连铸机的兴起以及在新建和改造的小型轧机中,逐步增加了连轧成分,轧机的原料规格有逐步加大的趋 The production of small rolling mills in our country generally requires high output and more variety of product specifications, so a reasonable and reliable supply of billet has a great influence on the normal production of rolling mills. At present, in addition to Angang, Shougang and other means of initial supply of better rolling means of 90 ~ 100mm square billet, the vast majority of small rolling mill about 60mm billet. In recent years, due to the rise of the billet caster and the gradual increase of the rolling components in the newly constructed and reformed small rolling mills, the raw material specifications of the rolling mills have gradually increased
