由北京钢铁研究总院研制的冷轧带肋钢筋轧机用硬质合金轨辊,已通过建设部及国家冶金局组织的技术鉴定。 轨辊的材质及生产工艺是决定轧辊质量的关键因素,国外工业先进国家的轧机刚度和精度高,轧辊受力均匀、冲击载荷小,采用一般冷压烧结工艺生产的硬质合金轧辊即能满足轧机需求。而国内轧机的整体水平低、刚度低、精度差,要求轧辊不仅具有高 Developed by Beijing Iron and Steel Research Institute of cold-rolled ribbed bar rolling mill with carbide rails, has passed the Ministry of Construction and the National Metallurgical Bureau of the technical appraisal. Roller material and production process is the key factor that determines the quality of the roller. In the advanced countries in the world, the rigidity and precision of the rolling mill are high, the force of the roller is even and the impact load is small. The carbide rollers produced by the common cold- Mill demand. The domestic rolling mill overall low level, low stiffness, poor accuracy, requiring not only high roller
