摘　　要：为了解决低氮微碳铬铁合金产品的品级率波动大、生产成本高等问题,研究分析了导致合金氮元素增加的主要原因,并制定了适合的工艺路线。通过生产实践证明,理论分析符合实际,通过工艺改进和提高,实现了品级率和市场占有率的提高。In order to solve the great grade rate and the high cost and so on of low nitrogen extra LC-ferrochome,it reseaches the main reasons that causes the enhance of N in alloy,and develops a suitable technology route. Through production practice,it testifies that the theoretical analysis is truthfulness. Through technology improvement,it achieves the enhance of grade rate and market share.
