为了更好地控制板形,六辊UCM冷轧机的中间辊在窜辊的基础上,还要施加弯辊力,因此在中间辊与工作辊的端部接触区域将产生较大的应力集中,使轧辊磨损加快,甚至出现剥落现象。利用影响函数法建立UCM轧机的辊系弹性变形数学模型。同时为了减少辊间接触压力峰值,在中间辊两端加直倒角进行过渡,并对中间辊的倒角参数进行优化,优化出了适合不同带宽的倒角形状参数,从而降低了轧辊端部的接触压力,减缓了轧辊的磨损,避免了轧辊剥落。 In order to better control the shape of the plate, the intermediate rollers of a six-roller UCM cold rolling mill also have to exert a bending force on the basis of the shift rollers, so that a greater stress concentration occurs in the contact area of ​​the intermediate rollers and the end portions of the work rollers , So that the roller wear and tear accelerated, or even spalling phenomenon. Establishment of Mathematical Model of Rolling Elastic Deformation of UCM Mill by Influence Function Method. At the same time, in order to reduce the peak contact pressure between the rolls, a chamfer is added at both ends of the intermediate roll to make the transition. The chamfer parameters of the intermediate roll are optimized to optimize the chamfer shape parameters suitable for different widths, thereby reducing the roll end The contact pressure, slowed the roll of wear and tear, to avoid the roll spalling.
