Description

Forging Rolls are the most important spare parts for the cold rolling industry. The quality of forging rolls directly affects the quality of sheets & coils. By our years of experience, we can supply good quality forging roll with uniformity hardness, premium wear resistance and anti-thermal crack performance.

Material

The forged rolls are used in wide cold strip mills of 2Hi, 4Hi, 6Hi reversing reduction mill and tandem mills, double reduction mills as well as temper mills and skin pass mills. The following table gives a general overview of our main grades for rolls and all kinds of the material are in ESR process
