一.GY-3型短应力线轧机在国内外使用现状及结构特点 1.使用现状传统的轧机牌坊是承受全部轧制压力(沿轧制方向的径向压力及沿轧辊方向的轴向压力)的主要机体,同时,还将轧制时所产生的倾翻力矩通过地脚螺栓传给机座基础,因此,要求它应有足够的强度及刚度.小型轧机为便于换辊。一般采用开口式或半 1.GY-3-type short-stress line mill at home and abroad use the status quo and structural characteristics 1. The use of the status quo The traditional rolling mill arch is to withstand all the rolling pressure (along the rolling direction of the radial pressure and along the direction of the roller axial pressure) Of the main body, at the same time, but also rolling the tipping torque generated by anchor bolts to the base of the base, therefore, it should be sufficient strength and rigidity. Small rolling mill for easy roll change. Generally open or semi-open
