Rolling of Steel in a Modern Long Product Rolling Mill

19/06/2017· Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills. Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size. The primary objective of the roll pass design is to

Effect of pass schedule and groove design on the metal

the two-pass and four pass roll schedules in the continuous hot rolling of a large diameter mandrel bar [7]. A large- deformation constitutive model to evaluate roll force and torque in heavy-reduction was found to be in agreement with Misaka–Yoshimoto model for dynamic recrystalliza-tion [8]. A variation in the rolling load was predicted as a result of non-uniform heating of the slab, in a

Analysis of Efficiency of Roll Pass Design Options for

The analysis of two roll pass design options of ten roughing stands atOJSC “MMK” 370 rolling mill has been performed. The usage of a new form of the roll grooves will allow achieving higher durability of the rolls. Lesser rolls consumption will allow saving up to 800K rubles annually. More uniform load distribution by the stands will reduce the possibility of main mill lines equipment

HOT ROLLING PRACTICE An Attempted Recollection

mill to several stands positioned either side by side or in a line. A mechanism, commonly called a roller table, directs the work piece to the rolls, and another roller table for handling the pieces emerging out of the roll. The table in front of the rolls forces the steel against the rolls which grip and pull the steel between them. Steel is, thus, reduced to a thickness equal . 2 to the
