二十辊轧机的结构特点和应用发展

Structural Characteristics and Application Development of 20 High Mill

通过研究引进的各类型二十辊轧机,分析比较其结构特点及实际应用情况,理清二十辊轧机的技术发展脉络,为二十辊轧机的选型、开发提供参考。以国内引进的整体式、四立柱式和分体式二十辊轧机为研究对象,分析了各类型二十辊轧机的结构特点以及相互联系,结合在不锈钢、硅钢轧制领域的实际使用情况,阐明了各型轧机具有的优点和缺点。国产二十辊轧机打破了引进型轧机的垄断局面,并迅速发展,为生产企业提供了更多选择空间。对于生产企业来说,整体式二十辊轧机依然是性价比较高的选择,考虑到不同的原料和产品的定位,可以采取整体式二十辊与四立柱式、分体式二十辊轧机相互配合的选型方案。

This paper studies the various types of 20 high mills introduced in China in recent decades,analyzes and compares their structural characteristics and practical applications,sorts out the technical development of 20 high mills,and provides reference for the selection and development of 20 high mills.This paper analyzes the structural characteristics and interrelation of the monoblock,four column and split 20 high mills introduced in China,and expounds the advantages and disadvantages of each type of rolling mill combined with the practical application in the field of stainless steel and silicon steel rolling.The domestic 20 high mill broke the monopoly situation of the imported mill,and developed rapidly,providing more choice space for the production enterprises.For manufacturers,the monoblock 20 high mill is still a cost-effective choice,taking into account the positioning of different raw materials and products,the selection scheme of the monoblock 20 high mill and the four column,split 20 high mill can be adopted.
