how to reverse the rougher in a hot strip mill

A reversing mill is a rolling mill in which the workpiece is passed forward and backward through a pair of rolls. The reversing mill is so named because the steel runs back and forth between the rollers, reducing the thickness incrementally with each pass. A reversing mill can be used to reduce material to gauge. Hot Rolling Mill . Apr 22, 2012 (Roll forming: ) This film takes you through the processes within a hot rolling mill

Hot strip mill - ArcelorMittal in Belgium

This is done in the reheating furnaces of the hot strip mill. A slab coming out of the furnace has a scale layer that needs to be removed before it can be rolled. The breaking and removing of the scale layer is done by a scale breaker, with its water jets that release a pressure of 120 bar onto the slab.

Width necking at the rougher in a hot-strip mill ...

At the rougher train in a hot-strip mill, as a slab is rolled by not only horizontal flat-rolls but also vertical edger-rolls, the width spread phenomenon is more complicated than in a simple flat-rolling process. The gap of edger rolls at each pass must therefore be predictively controlled to compensate for the width spread during the above-mentioned flat-rolling. The other problem is securing a final strip with

Width necking at the rougher in a hot-strip mill ...

The amount of necking is determined mainly by the conditions of rougher rolling in the hot-strip mill. In this paper, the mechanism of necking, the influence of rolling conditions on the amount of necking and the optimum edger-rolling pass schedule are described. The main conclusions obtained are as follows: (i) Necking originates from the uneven distribution of dog-bone height along the length of a slab and the
