Rolls Manufacturing and Materials Requirements​
Konstantin Redkin, WHEMCO
This portion of the class will focus on understanding the rolls’ service life cycle from manufacturing steps to the final scrap diameter. The emphasis will be made on understanding the basics of the mill loading during cold rolling, using finite element analysis of the 4-high roll stack. The cold work roll’s material requirements will be discussed based on modern damage tolerance criteria. Microstructure evolution in the roll ingots and depth of hardening will be covered by explaining manufacturing thermomechanical routes.
