针对采用常法浇注的中镍铬钼冷硬铸铁普线轧机精轧辊白口深度控制难,质量合格率低,轧辊强度低,断辊时有发生的问题,中合金冷硬离心轧辊被成功研制并推广应用,用其替代常法浇注的中镍铬钼冷硬轧辊,耐磨性和强度都有大幅度提高,基本上解决了工作层厚度和断辊的技术难题。 In view of the common method of casting chrome molybdenum chrome cast iron normal line mill fine white roll deep mouth control difficult, the quality of pass rate is low, the roll strength is low, there are problems when the roller, the alloy chilled roll was successfully developed And to promote the use of its replacement of the normal method of casting chrome molybdenum chrome cold roll, wear resistance and strength have greatly increased, basically solved the working layer thickness and the technical problems of broken roller.
