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).

The free torsional stiffness of hot-rolled section steel is higher than that of cold-rolled section steel, so the torsional resistance of hot-rolled section steel is better than that of cold-rolled section steel. Free send inquiry to stella@hanrm if any needs. Whatsapp/Wechat:+86.

Forged work rolls for cold rolling have undergone numerous developments over the course of the last few years (Ref 1).The most recent development for cold work rolls is focused on the family of semi-high-speed steel (S-HSS) grades (Ref 2, 3).So far, the S-HSS grades have already proved that they bring about a significant improvement in roll performance.

75 ~ 85 HSC. Tungsten Carbide. 78 ~ 85 HRA. CPC**. 75 ~ 90 HSC. *TR1 is a special material which wears better than traditional materials. It is designed to be used at early and medium stands for long products. **Hardness determination based on mill application. General roll recommendation for Structural Mills.

In the mid 80´s, this roll type became a standard roughing mill work roll grade. The semi-HSS grade is characterized by a matrix of tempered martensite with a strong effect of temper hardening, where special carbides of Figure 4.a: Phase volume fraction evolution on cr-steel the M7C3, M6C and MC type are embedded. ...
