Importance of molybdenum in molybdenum industry
نوشته شده توسط : sdgf



Molybdenum is a metallic element which was not discovered until 1992 when it was extracted from molybdenite by a Swedish chemist. Because of its high intensity, high melting point, corrosion resistance and abrasion resistance, the molybdenum metal is widely used in industry.

In metallurgical industry, molybdenum is used as an additive for producing various kinds of continuous belt dryer or used together with W, Ni, Co, Zr, Ti, V, Re and so on for making high-grade alloys, to raise their high-temperature intensity, abrasion resistance and corrosion resistance. Molybdenum-bearing alloy-steel is used to manufacture transportation conveyances, locomotives, industrial machinary, and various kinds of instruments. Some stainless steel, containing 4%~5% molybdenum is used to produce precision chemical-industrial instruments and equipment used in the seawater environment. The high-speed steel, containing 4%~9.5% molybdenum can be used to manufacture high-speed cutting instruments. An alloy of molybdenum, nickel, and chrome is used for manufacturing metallic components of airplanes, and corrosion-resisting spare parts of locomotives and cars. An alloy of molybdenum, tungsten, chrome and vanadium is used for manufacturing alloy components and spare parts of warships, tanks, firearms, rockets and satellites.As the professional manufacturer of complete sets of mining machinery, such as mobile crushing station,Rotary dryers, Henan Hongxing is always doing the best in products and service.

A large quantity of rotary dryer machine is used as heating material and structural material for high-temperature electric furnace, as large-scale electrode and grid electrode of vacuum tube, as semiconductor and electrooptical source material. Because of its small thermal-neutron capture cross-section and its high lasting intensity, molybdenum also can be used as structural material for nuclear reactor.

In chemical industry molybdenum is used mainly as lubricating agent, catalyst and pigment. Because of its laminated crystal structure and surface chemical property as well as its good lubricating behaviour under high temperature and high pressure, spray dryer china is used widely as an additive for grease and oil. Molybdenum is a component of the catalyst in the desulfurization during hydrogen production and in other processes of industrial spray dryer, as well as in the redox reaction for producing alcohol, formaldehyde and oil-base chemicals. The molybdenum orange colour is an important pigment. The molybdenum chemicals are widely used in dyestuff, ink, colour-precipitated dyestuff and antiseptic priming paint.
