Hot Rolling is employed for rolling of steel slabs to hot strips in hot strip mills. Like any other hot rolling operations, rolling of hot strip is also a plastic deformation of the material of the slab caused by compressive force applied through a set of rolls. The cross section of the slab is reduced by the hot rolling process.

John G. Lenard, in Primer on Flat Rolling Second Edition, 2014 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill.

HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a key element of steel production.

Two rolls (inner) are work rolls and four rolls are back-up rolls. This configuration is normally used in cold rolling of steel strip. Cluster mill roll configuration – In this type of roll configuration, there are six, seven, twelve, or twenty horizontally mounted rolls. In all the mills having this configuration, there are only two rolls ...

Hot Strip Mill an overview | ScienceDirect Topics. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).

Typically, back-up rolls in hot strip mills are equipped with sliding bearings and it is common to use a key that prevents relative motion between the conical sleeve and the roll shaft.

New rolling mill designs Roll stand back-up rollers are precision machine elements that give optimum functioning and achieve their maximum operating only if they are precisely matched to the application. When new enquiries are received for roll stand back-up rollers, a wide range of technical data are therefore required in order

Main Features of a modern Hot Strip Mill. The objective of a hot strip mill (HSM) is to reheat and roll thick slabs into thin strip with a wide range of thickness. Because of its huge size and large investment a hot strip mill need to have a life time of several decades. The mill must be capable of meeting the market demands for a wide range of ...

The primary function of the conventional hot strip mill (HSM) is to reheat the semi-finished steel slabs (rolled or continuously cast) to the rolling temperatures and then to roll them thinner and longer through a series of rolling mill stands driven by large motors and finally coiling up the lengthened steel sheet for its easy handling and transport.

In this tandem mill types of rolling mill, It includes of a number of non-reversing two-high rolling mills provide one after other. So that the material can be passed through them all in order. This is only suitable for mass production work, as lower volumes require a quicker change of set up and they will consume a lot of labour and work.

Typically, back-up rolls in hot strip mills are equipped with sliding bearings and it is common to use a key that prevents relative motion between the conical sleeve and the roll shaft. The key groove causes deformation of the sleeve under load.

Abstract During the first year of production in the 2250 mm hot strip mill of Qian'an Iron and Steel Company of Shougang Steel Corporation, roll spalling and broken rolls were frequent occurrences, especially on the second stand of roughing mill (R2), and resulted in enormous economic losses. In addition, improvements to strip shape were required.

The rolls are monoblock cast so no shell / core interface problems. Application: Back Up Rolls for 4-Hi Stands of Hot and Cold Strip mills and CSP Mills. Work Rolls for 2-Hi roughing Stands of Hot Strip Mills (3% Cr).

Abstract Typically, back-up rolls in hot strip mills are equipped with sliding bearings and it is common to use a key that prevents relative motion between the conical sleeve and the roll shaft. The key groove causes deformation of the sleeve under load. This sleeve 'spring' is observed as rolling force variation, which causes systematic thickness variation of the steel strip.

Endless Hot Strip Rolling Process . In conventional hot strip production, slabs of thickness of about 250mm are heated in a furnace and are reduced to 30 to 60mm in thickness after passing through the roughing mill, and then further reducing it to within a range of 0.8 to 25.4mm by rolling in the finishing mill.
