High-chromium steel sheet with work rolls in the roughing zone

Main features:

The working layer of the high-chromium steel centrifugal composite roll contains 8%-15% of chromium alloy elements, and the core is high-strength ductile iron. Due to the action of a large amount of chromium alloying elements, the carbide in the working layer structure is M7C3 type carbide; this type of roll has undergone special heat treatment, so that the roll has good wear resistance, hot crack resistance, bite resistance and high temperature comprehensive performance .

Main use:

Rough rolling work rolls and vertical rolls for hot strip steel.
