随着国民经济的发展,日益要求冶金工业提供更多更好的优质钢和性能良好的合金铸铁轧辊。由于钢和铸铁中加入微量的(0.15~0.6%)稀有元素——钼,具有细化均匀组织,扩大淬火回火温度范围,提高材料力学性能和改善材料热稳定性等一系列优点。因此,在国内外广泛的采用以钼与钒、铬等元素配合使用,冶炼优质钢和合金铸铁。目前钼已成为发展冶金工业不可缺少
With the development of the national economy, the metallurgical industry is increasingly required to provide more and better high-quality steel and good-performance alloy cast iron roll. Due to the addition of a trace amount of (0.15-0.6%) molybdenum and molybdenum to steel and cast iron, it has the advantages of refining and homogenizing the microstructure, widening the temperature range of quenching and tempering, improving the mechanical properties of the material and improving the thermal stability of the material. Therefore, the widespread use of molybdenum and vanadium, chromium and other elements with the use of smelting of high-quality steel and alloy cast iron. At present, molybdenum has become indispensable for the development of metallurgical industry
