本文通过对有色精轧辊的使用调查,解剖实物和淬硬层的金相组织分析,找到了精轧辊不耐磨的主要原因。采取了改进材质及改革淬火工艺的技术措施,取得了增加淬硬层深度;减少淬硬层金相组织申屈氏体及残余奥氏体等不耐磨组织的量;提高奥氏体晶粒度等效果,有效地提高了有色精轧辊的耐磨性,获得了提高轧辊寿命,降低辊耗的经济效益。 In this paper, the investigation of the use of colored finishing rollers, the dissection of physical and hardened layer of the microstructure analysis to find the main reasons for non-wear fine rollers. Taken to improve the quality of materials and technical measures to reform the quenching process has been made to increase the depth of hardened layer; to reduce the hardened layer metallurgical microstructure such as Invasive and residual austenite and other non-wear-resistant organizations improve the amount of austenite grain Degree and other effects, effectively improve the wear resistance of colored finish roll, get the roll life and reduce roll economy.
