目前我国不少中小型钢铁厂还使用工艺落后的横列式轧机,产品质量往往不能保证。实践证明,若将这类轧机在保证工艺布置、传动方式和设备基础均不改变的条件下,改造成短应力线轧机,则新轧机机架的刚度将成倍地增加,产品尺寸精度可大为提高,产品质量得到相应的改善,可以满足国家现行标 At present, many small and medium-sized steel mills in our country also use the out-dated rolling mill, and the quality of their products is often not guaranteed. Practice has proved that if these types of mills in ensuring the process layout, transmission and equipment are not changed under the conditions of the foundation into a short-stress line rolling mill, the rigidity of the new mill stand will increase exponentially, the product size accuracy can be large To improve, product quality has been improved accordingly, to meet the current national standard
