一、高刚度轧机高刚度轧机可分为预应力和短应力线轧机两大类。如北京钢铁学院设计的GY型短应力线轧机,威远钢铁厂的高刚度轧机,河北省冶金厅、邯郸冶金机械厂研制的HB型无牌坊轧机,鄂城钢铁厂采用的预应力轧机以及长城钢厂引进的P500无牌坊轧机等均为高刚度轧机。现简介如下: First, the high stiffness mill High stiffness mill can be divided into prestressed and short stress line mill two broad categories. Such as the Beijing Institute of Steel designed GY-type short-stress line mill, Weiyuan steel mill high-rigidity mill, Metallurgical Office of Hebei Province, Handan Metallurgical Machinery Factory developed HB unlicensed Square Mill, Echeng Iron and Steel Plant used prestressing mill and the Great Wall The P500 unlicensed workshop mill introduced by the steel mills are all high-rigidity rolling mills. The brief introduction is as follows:
