Thanks for your interesting in nordular cast iron rolls of tube mill
INTRODUCE：
Hardness uniformity and wear resistance are the key factors in the process of tube producing. In this principle, we have developed high quality bainite nodular cast iron roll. The worldwide practice proves that this material is the most economical and suitable material for hot tube rolling. Based on the traditional process, we optimized the technology of the rolls of nodular cast iron. We are the best seamless tube roll supplier in China. Our products are widely used in the domestic and international seamless steel tube mill. We have a lot of successful application in India,Russia, not only the Kocks SRB and Extractor rolls but also the rolls for FQM machine.
