钼加入钢中可使钢具有均匀的细晶组织,提高钢的淬透性,并能消除镍铬钢的回火脆性,提高钢的强度、弹性限度、抗磨性。钼元素通常以钼铁或氧化钼块形式加入钢中。我厂采用外加热式回转窑氧化焙烧辉钼矿,生产钼铁和氧化钼块产品。 Molybdenum added to the steel can make the steel have a uniform fine grain structure, improve the hardenability of steel, and can eliminate the temper brittleness of nickel-chromium steel, improve the strength of steel, elastic limit, abrasion resistance. Molybdenum is usually added to steel as molybdenum or molybdenum oxide. I plant using external rotary kiln oxidation roasting molybdenum mine, molybdenum and molybdenum production of block products.
