Process method for smelting high-manganese steel

The invention relates to the field of smelting, and provides a low-cost high-manganese steel smelting process, which adopts intermediate frequency furnace full scrap steel smelting and LF furnace refining treatment, and adopts a process route of intermediate frequency furnace-LF-die casting, reduces the addition amount of high-manganese steel precious alloy, reduces the smelting cost, does not need oxygen blowing in the whole smelting process, does not need reduction, and improves the smelting efficiency. Inclusions generated in the normal smelting process are reduced, the technological process is short, treatment is simple, and the smelting period is shortened. By adopting the process, the yield of manganese can be increased to 99% or above, and good economic benefits and social benefits are generated. 本发明涉及冶炼领域，提出了一种低成本高锰钢冶炼的工艺方法，过程采用中频炉全废钢冶炼加LF炉精炼处理，采用"中频炉→LF→模铸"工艺路线，降低了高锰钢贵重合金加入量降低了冶炼成本，冶炼全程不需要吹氧不需要还原，减少了正常冶炼过程产生的夹杂物，本工艺流程短，处理简单，缩短了冶炼周期。采用该工艺锰的收得率提高可达到99%以上，产生了很好的经济效益与社会效益。
