This paper describes the transition to high-hardness compound steel wear plates for housing and chocks in rolling mills. Premature wear of liners has a great impact on overall rolling mill stability and product quality. Compound steel allows operators to have the same hardness wear liners while simultaneously protecting the mounting surfaces from impacts and damage. There is no need for sacrificial, softer liners, and overall mill clearance can be maintained as designed. Detailed long-term studies in regard to overall reduction in wear; positive impact on gearboxes, bearings and work roll stability; and reduction of chock and roll shop maintenance will be presented.
