摘　　要：通过优化连轧辊的化学成分、生产工艺等关键控制点,对比分析了优化前后连轧辊的力学性能和显微组织,结果表明采用金属型喷涂工艺开发连轧凹面辊,提高了铸铁轧辊的工作层硬度和耐磨性,降低了人工劳动成本,为将来开发大型带槽轧辊和辊环提供了技术基础。In the paper, it is found that the hardness and wear resistance of working layer for cast iron roll are improved as well as the labor costs are reduced by developing continuous rolling concave roll with the metal spraying process through optimizing such key control points as the chemical composition and production process of continuous rolling roll as well as comparing and analyzing its mechanical properties and microstructure before and after optimization, which provide the technical basis for developing large grooved roll and roll collar in future.
