短应力轧钢机械的应用
　　短应力轧钢机械又称为无牌坊轧机,是一种高刚度轧机,在做为型钢轧机使用时,它不仅应该具有较高的径向刚度,而且还应该具有较高的轴向刚度。目前国内已经研制出多种型式的短应力轧钢机械如:GY型,HB型,CW型,SY型,GW型,DW型等,其中有代表性的有三种，它们是GY型短应力线轧机,HB型无牌坊轧机,SY型高刚度轧机。这几种轧机都是参考了瑞典的P一60型无牌坊轧机,结合各自不同情况自行研制的,所以它们主要受力部份的魁应力线结构是相似的,只在支承方式及某些具体结构上有些不同,各有其特点。

The application of short-stress steel rolling machinery

Short-stress steel rolling machinery, also known as a frameless rolling mill, is a high-stiffness rolling mill. When used as a section steel rolling mill, it should not only have high radial stiffness but also

 high axial stiffness. At present, various types of short-stress steel rolling machinery have been developed in China, such as GY type,HB type,CW type,SY type,GW type,DW type, etc. Among them, three 

representative ones are the GY type short-stress wire rolling mill,HB type non-bar rolling mill, and SY type high-stiffness rolling mill. These several types of rolling mills were all independently 

developed by referring to the Swedish P-60 type rolling mill without a plate, taking into account their respective different circumstances. Therefore, the stress line structures of their main force-bearing 

parts are similar, with only some differences in the support methods and certain specific structures, each having its own characteristics.
