discuss steel rolling mill rolls

Wear of hot rolling mill rolls: an overview - ScienceDirectRolling is today one of the most important industrial processes because a greater volume of material is worked by rolling than by any other technique. Roll wear is a multiplex process where mechanical and thermal fatigue combines with impact, abrasion, adhesion and corrosion, which all depend on system interactions.discuss steel rolling mill rolls,a basic understanding of the mechanics of rolling mill rolls - BRCI expect to edit some more re-written chapters later. Especially I am waiting for results from "roll cooling simulation" to give my theory of fire-cracks more background. Secondary scale on hot strip and the impact on wear is another issue. Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured.
