我国一般使用的小型轧机,由于弹性变形大,产品精度不高,只能达到标准规定的较低精度。与国外同类产品相比,尺寸精度处于劣势。为此,近年求,北京钢铁学院等单位大力推广刚度系数火、弹性变形小的高刚度轧机。力求减小由于设备精度差而造成的产品尺寸波动。一、目前常见的几种高刚度小型轧机 1.预应力轧机西德奥尔特纳(Ortner)等人曾证明,在机架尺寸、材质、轧制力等相同时,预应
Small mill generally used in our country, due to large elastic deformation, product accuracy is not high, only to meet the lower precision standards. Compared with similar foreign products, dimensional accuracy at a disadvantage. To this end, in recent years, seeking, Beijing Iron and Steel Institute and other units vigorously promote the stiffness coefficient of fire, small elastic deformation of high rigidity rolling mill. Strive to reduce due to poor precision equipment caused by product size fluctuations. First, the current common several high rigidity small mill 1.
