轧辊是轧钢生产中消耗量很大的工具。随着轧制设备向着大型化、高速化、自动化方向迅速发展,对轧辊的性能和质量要求越来越高。锻造钢性铸铁轧辊强韧性高,耐磨损,耐热裂性能好,兼备钢系和铸铁系轧辊的优良性能,可明显提高轧辊的使用寿命。近年来,日、美等工业发达国家竞相研制锻造钢性铸铁轧辊。机械工业部重矿局于1982年组织了我院与第一重型机器厂合作研制钢性铸铁轧辊。在两年多的时间内,联合 Rollers are a very expensive tool for rolling production. With the rolling equipment toward large-scale, high-speed, rapid development of automation, the performance and quality of the roller is getting higher and higher. Forged steel cast iron roll high toughness, wear resistance, good thermal cracking performance, both steel and cast iron roll excellent performance, can significantly improve the service life of the roll. In recent years, Japan, the United States and other industrialized countries competing for the development of forged steel cast iron roll. Heavy Mining Bureau of the Ministry of Machinery Industry in 1982 organized our hospital and the first heavy machinery plant in cooperation to develop steel cast iron roll. In more than two years, united
