Width necking at the rougher in a hot-strip mill

Apr 01, 1983· One is securing the expected final strip-width with minimized mill margin. 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.

What is a Reversing Mill? Definition from Corrosionpedia

Mar 17, 2014· The purpose of the reversing mill is to reduce the thickness of the steel to the customer’s specifications. The hot roll band passes back and forth between the rolls until it reaches the specified thickness. Benefits of reversing mills include: Flexible, low-cost rolling of a wide range of products; Tight strip thickness and shape tolerances

John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. 2.7 Generation III Coil Box Hot Strip Mills. In the 1970s, Stelco of Canada developed the hot coil box designed for installation in hot strip mills ahead of the finish mill for coiling the transfer bar from the roughing mill and uncoiling it into the finishing mill. The coil box reduced the distance between the roughing mill

ROBUST STEERING CONTROL OF HOT STRIP MILL

A hot strip mill (HSM, Fig. 1) is the association of n stands in a line, where each stand is constituted by a set of rolls. The lateral movement of the strip, with reference to the mill axis, is the consequence of rolling asymmetries linked to the stand, such as differential stand stretching or work rolls tilting.

Camber free rolling for roughing stands SMS group

You face rolling problems in the finishing mill and an increased likelihood e.g. of tail end breaks. This is where camber-free rolling comes in. It's based on the interaction of roll alignment control integrated in our automation system and strong, position-controlled side guides in the roughing mill stand entry and exit sections. Here's how it

Hot strip mill ArcelorMittal in Belgium

Hot strip mill. Around a third of the products we send out to our customers, are hot rolled. In the hot strip mill (Ghent), slabs coming from the continuous caster are rolled out to steel plates with a thickness of around 1.25 to 13mm. How does this work? First, the slabs coming from the continuous caster are pre-sorted in the slab yard.
