Product Description Unit price will be decided by engineering drawing.Introduction:Work 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. All of our work rolls are manufactured by the ESR process, which guarantee the characteristics of rolls,1. No macroscopic segregation and few microscopic segregations.2. Very few and subtle non-metal inclusion; dispersed distribution.3. Compact and homogeneous structure.4. High toughness and strength5. Beneficial for improvement of anti-fatigue and heat impact ability of the roll.Material and Properties:The following table gives a general overview of our main grades for rolls and all kinds of the material are in ESR process.
