Stainless steel raw materials: molybdenum development

The main areas of consumption of molybdenum in the steel industry, the industrialized countries more than 80% of molybdenum as an added element of steel, only about 20% of the molybdenum metal used to produce molybdenum, super alloys and special alloys, chemicals, etc., consumed in oil chemical industry, light industry, electronics and some high-tech areas.Molybdenum and molybdenum alloy rods (bars), wire, sheet, strip, foil and shaped products commonly used in metallurgy, machinery manufacturing,stainless steel wire electronics, lighting and some high-tech fields. Stainless Steel Shaped Wire The illumination filament stent mandrel wire, reflective screen; electronics industry with an anode, a gate and an auxiliary electrode, gasket; vacuum plating, sputtering with the container, a boat, a heater; heat generating element used in a high temperature furnace electrodes, heat shields; surface treatment used for welding, spraying; thermocouple and temperature with protective cover; UO2 refining was burned by boat and so on. The last 10 years, the application of molybdenum was given a further expansion, such as molybdenum powder or molybdenum wire thermal spraying greatly improves the life of the piston rings and gear parts on the car; in glass and fire-resistant fiber material industry, molybdenum can be replaced previous platinum crucibles and electrodes, and achieved great results. The emergence of high-temperature molybdenum, mercury and molybdenum in a vacuum oven halogen range of applications is growing.Stainless steel wires In die-casting industry, molybdenum and alloys can be used as non-ferrous and ferrous metal casting mold material. Molybdenum-based ceramic heat pipe suitable for BOF steelmaking process of continuous measurement of the casing, hot extrusion die; molybdenum alloys are widely used to wear head seamless steel and stainless steel pipe system, significantly improve productivity and product quality, reduce costs. Molybdenum and tungsten alloy formation, its anti (liquid zinc and zinc vapor) particularly excellent corrosion resistance, has generally produced using Mo-30W alloy casing vertical and temperature, greatly reducing maintenance downtime, improve working conditions. MoSi2 oxidation resistance particularly good, use it as a working temperature up to 1700 ℃ heating elements in the atmosphere, but also as a rare earth smelting and some single crystal pulling crucible, instead of precious platinum crucible.
