Reasonability to use device for making horizontal wedge thrust of rolling stand

Abstract

Necessity and reasonability to use gapless connection between contact surfaces of lining straps of work rolls chocks and facing strips of housings (inner lining straps of back-up rolls chocks) to reduce dynamic horizontal forces during rolling and increase durability of equipment are considered. Technical solution is described on base of roughing reversing rolling stand of thick sheet rolling mill 3000 of PJSC ‘ILYICH iron and steel works’ (Mariupol city, Ukraine) which can be used on most heavy loaded sheet and tube rolling mills.

Experimental study of horizontal impact forces acting on equipment of thick sheet rolling stands during rolling

“…Done calculations of horizontal forces of BWR chocks impacts against housings provided execution of stress calculations of technical solutions for increase of rolling stands durability [7][8][9][10][11][12].…”

“…Stabilization of work of main drive lines of thick sheet rolling mills during increase of their productivity is important task [4][5][6]. Theoretical data of dynamic loading of rolling stands (that was proved experimentally) was used to make stress calculations of technical solutions for reduction of impact loads [7][8][9][10][11][12].…”
