The atomic weight of molybdenum is 95.94. The outer electronic structure is 4d55s1, the melting point is 2615℃, the boiling point is 4610℃, and the density (20℃) is 10.2g/cm3. The binary phase diagram of molybdenum and iron is shown in Figure 1. Molybdenum and iron form α and γ solid solutions and two intermetallic compounds ε (Fe7Mo6) and σ (FeMo) phases. Industrial ferromolybdenum contains about 60% Mo, the melting temperature is 1800-1900 ° C; the density is about 9.0g/cm3. Ferromolybdenum is an iron alloy obtained by smelting molybdenite or calcined molybdenum concentrate in an electric furnace. It is mainly used as an alloying element additive for smelting magnetic steel, structural steel and high-speed steel. The ferromolybdenum produced in my country contains about 55% molybdenum. If the steel Chemicalbook contains only a small amount of molybdenum, calcium molybdate can be used as an element additive, and the cost is much lower than that of ferromolybdenum. The role of molybdenum in steel can be summarized as improving hardenability, improving thermal strength, preventing temper brittleness, improving remanence and coercivity, and corrosion resistance in certain media, and preventing pitting corrosion. Due to the various beneficial effects of molybdenum in steel, it is used in a series of steel grades such as structural steel, spring steel, bearing steel, tool steel, stainless acid-resistant steel, heat-resistant steel (also known as heat-strength steel), and magnetic steel. , has been widely used. Molybdenum is very effective in improving strength and toughness in cast iron. When the addition amount is 0.25% to 1.25%, it can also form pearlite matrix structure for castings with medium and large sections. Commonly used in rolls and other wear-resistant castings.
