为了探讨添加稀土对高锰钢组织和性能的影响,在工业生产条件下进行了一系列试验。试验用钢在碱性电弧炉中采用氧化法冶炼。精炼末期,待渣中FeO与MnO含量之和低于1.5%,化学成份合格后,插铝0.5公斤/吨,然后加入硅铁稀土,再插铝0.5公斤/吨出炉。各试验炉号的化学成份及稀土加入量如表1:浇注成梅花试棒、观察低倍组织的 In order to investigate the effect of rare earth addition on the microstructure and properties of high manganese steel, a series of tests were carried out under industrial production conditions. Test steel in the alkaline arc furnace oxidation method smelting. At the end of refining, the sum of FeO and MnO content in the slag should be less than 1.5%. After the chemical composition is qualified, insert 0.5kg / t of aluminum, then add ferrosilicon and rare earth, insert 0.5kg / t of aluminum. The test furnace number of chemical composition and the amount of rare earth added in Table 1: pouring plum blossom test sticks to observe the low magnification
