Conference on Abrasion Wear Resistant Cast Iron And Forged Steel For Rolling and Pulverizing Mills – ABRASION 2024

Delivering consistent product quality and optimizing processing conditions in a cold rolling mill requires a proper understanding of back up roll wear. This paper describes the development of an analytical wear model in rolling contact that integrates the contact mechanics of tractive rolling and Archard’s wear model. The model is developed for two facing cylinders. Then this model is expanded...

Back-up rolls (BURs) in cold and temper rolling mills often exhibit very inhomogeneous wear rates over their barrel length. Associated profiles have a large effect on local stress distribution along the BUR-WR (work roll) contact length, which may impact subsequent stages of BUR (sub)surface degradation, which in turn affects strip profile or flatness. A poor prediction of BUR profile loss,...
