近年来,我厂参考有关资料并结合过去的试验数据,对铸钢轧辊的化学成分作了一系列的研究和改进。认为提高碳和锰含量,可以提高轧辊的强度、硬度和耐磨性。根据有关文献介绍,共析钢和过共析钢轧辊的耐磨性较亚共析钢良好,但过共析钢由于组织中出现较多的渗碳体,必须用比较复杂的热处理工艺才能使渗碳体球化而使轧辊强度和韧性不致显著降低。由此看来,以共析钢或接近共析钢作为轧辊的成分是比较
In recent years, I plant with reference to the relevant information and the past experimental data, the chemical composition of the cast steel made a series of research and improvement. It is believed that increasing the carbon and manganese content improves the strength, hardness and wear resistance of the rolls. According to the relevant literature, the eutectoid steel and eutectoid steel roll wear resistance than hypoeutectoid steel is good, but the eutectoid steel due to the organization appear more cementite, you must use more complex heat treatment process to make The cementation of cementite causes the roll strength and toughness not to be significantly reduced. From this, the composition of eutectoid steel or near eutectoid steel as a roll is compared
