奥氏体高锰钢的抗拉力和延展性很高,耐磨性和冲击韧性良好,受到突然冲击时不致破坏,故广泛用于机械工业中,特别是破碎机、球磨机等的零件。我厂过去生产高锰钢,仅用碱性电炉氧化法熔炼。1952年开始试用不氧化法。1956年又试验成功以酸性电炉熔炼,熔炼时间显著缩短,产量大大提高。后又改将全部锰铁加入包内,使锰的回收率达到90～98％。去年以来,对有关提高质量的几个问题亦进行了研究。现将生产情况简述如下。
Austenitic high manganese steel high tensile strength and ductility, good wear resistance and impact toughness, when subjected to sudden impact will not be destroyed, it is widely used in the machinery industry, especially crusher, ball mill and other parts. I plant in the past production of high manganese steel, alkaline furnace oxidation only smelting. In 1952 trial non-oxidation method. In 1956, the trial was successfully smelted in an acid electric furnace, the melting time was significantly shortened, and the yield was greatly increased. Later changed all the ferromanganese into the package, the manganese recovery rate of 90 to 98%. Since last year, several issues concerning quality improvement have also been studied. Now the production is briefly described below.
