冷轧多辊轧机的工作辊由于工作条件苛刻,通常采用高碳、高合金钢的材质,并且通过淬火热处理以得到隐晶马氏体组织来达到高硬度、高强度、高耐磨性及抗事故的能力。由于轧辊选用的材质及采用的热处理工艺不同,所得到的组织仍有很大的差别,本文着重对几种不同材质的轧辊经不同的热处理工艺后的组织进行显微及电镜观察,结合其性能进行一些探讨,以寻找合理的材质和热处理制度。
Due to the harsh working conditions, the work rolls of the cold-rolling multi-roll rolling mill usually adopt the material of high-carbon and high-alloy steel and obtain the high hardness, high strength, high abrasion resistance and resistance through the quenching heat treatment to obtain the cryptocrystalline martensite structure Accident ability. Due to the choice of roll material and the heat treatment process used, the resulting organizations are still very different, this article focuses on several different materials of the roll after different heat treatment microstructure and microstructure of the organization, combined with its performance Do some research to find a reasonable material and heat treatment system.
