AC adjustable speedmotordrive systems are the preferred technology for newrolling millinstallations and modernization projects. TMEIC designs and manufactures two types of AC solutions for this purpose. Salient pole synchronous motors that meet the high power and torque demands of a hot stripmill, as well as roughing and finishing stands.

After reading this article you will learn about thedesignofrolling mills. Arolling millincludes one or more roller stands, a main drivemotor, reducing gear, stand pinion, flywheel, and coupling gear between the units. The roll stand is the main part of themill, where therollingprocess is actually done.

At 25 RPM with a 1 HP motor the final torque is ~2250 inch pounds. This means with a 2.125" diameter roller the mill has 2000 pounds of "push" on the steel (limited by friction). There is a lot of room for changes and adaptations of available (scrap?) parts in the drive train.
