In this video, we explore the materials and manufacturing processes of hot rolling mill rolls, which are essential in the production of billets, thick plates, and steel sections. Common materials for these rolls include 55Mn2, 55Cr, 60CrMnMo, and 60SiMnMo, all of which must endure tremendous rolling forces, severe wear, and thermal fatigue during operation.

The manufacturing process typically involves integral normalizing or quenching treatments to ensure the rolls can withstand the demanding conditions. The surface hardness of the rolls is required to fall between HB190 and HB270, ensuring durability and reliability in high-stress environments.

Discover how the right material selection and manufacturing processes contribute to the performance of hot rolling mill rolls in steel production.
