1780 hot continuous rolling finishing area work roll (improved high nickel-chromium roll)

Main features:

The working layer of the improved high-nickel-chromium centrifugal composite roll is made of high-alloy material, and the core is made of high-strength ductile iron. Since the structure of the working layer of the roll contains 25%-40% carbide and a small amount of graphite, the matrix structure is bainite or sorbite, which makes the roll have good wear resistance, good spalling resistance and resistance Thermal cracking.

Main use:

Hot-rolled strip finishing work rolls, finishing work rolls of medium and heavy plate mills, work rolls of skin pass mills.
