摘　　要：分析了传统炼钢钼产品（钼铁、氧化钼）的生产工艺及其在应用过程中存在的问题,介绍了新一代钼冶金产品的生产工艺,并对新型炼钢产品的性质进行了研究.结果表明,钼铁和氧化钼的生产过程能耗高、污染较大,在炼钢过程中总收得率较低;而新型炼钢钼产品生产工艺简单,几乎无环境污染,冶炼过程中回收率高.所得到的新型炼钢钼产品呈疏松多孔状,堆积密度约为3.2~3.3 g/cm3,真密度为6.0~8.5 g/cm3,孔隙率为45%~60%,钼质量分数较高,杂质质量分数很低,在使用过程中收得率高,对现有的炼钢合金化流程影响小,因此可作为一种优质的炼钢钼产品.The problems in the production process of molybdenum products （molybdenum iron and molybdenum oxide） used in steelmaking were analyzed,and a new process of molybdenum metallurgy was introduced and the properties of molybdenum products were studied. The results show that the production process of molybdenum iron and molybdenum oxide was high energy consumption,serious pollution and the yield in the steelmaking process was low. While the new production process of molybdenum products was a simple process with almost no pollution and high recovery. The ob-tained new molybdenum product was porous state,with a bulk density of approximately 3.2-3.3 g/cm3,a true density of 6.0-8.5 g/cm3 and a porosity of 45%-60%. The molybdenum content of the new product was higher and impurities content was lower. When the new product was used in the steelmaking process,it can be used as an excellent molybdenum prod-uct because it has little impact on the steelmaking process and the yield was higher.
