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.
Highlights
Stands of rolling mills undergo bigger loads when masses of rolled metal are increased compared to initial ones
Rolling speeds are increased in order to improve productivity of rolling mills but it results in increase of dynamics of stands main drive lines [1,2,3,4,5,6]
Dynamics of rolling stands can result in their expensive accidental breakdowns
Summary
Stands of rolling mills undergo bigger loads when masses of rolled metal are increased compared to initial ones. Rolling speeds are increased in order to improve productivity of rolling mills but it results in increase of dynamics of stands main drive lines [1,2,3,4,5,6]. Dynamics of rolling stands can result in their expensive accidental breakdowns. Dynamics results in plastic deformation of housings windows, facing strips, lining straps and chocks [7,8,9,10,11]. It is expansive to revamp described parts of rolling stands equipment
