棒材、线材轧机的轧辊通常是由铸铁或铸钢制造的。需要精细加工。当轧辊达到报废直径废弃时,材料和加工费就损失了。因此用昂贵的材料制造轧辊就不太合理。虽然高性能的昂贵材料能提高轧辊的利用率和较好的轧材质量,却长期未被广泛采用。 Bar, wire rod mill roll is usually made of cast iron or cast steel. Need fine processing. When the roll discarded scrapped discarded, the material and processing costs lost. Therefore, it is less reasonable to make rolls with expensive materials. Although high-performance and expensive materials can improve roll utilization and better rolled material quality, they have not been widely used for a long time.
