- 80000tons/year
Roll performance: The outer layer composition has lower carbon content and higher chromium alloy content. After the roller is quenched and tempered multiple times, the outer layer structure is tempered bainite + carbide, and the strength and impact toughness are significantly improved. , the core is made of high-strength ductile iron, and its overall performance is significantly better than other cast steel support rollers.
