Application of Molybdenum Metal Bar
Conventional molybdenum strip is mainly made of molybdenum wire; High temperature molybdenum strip can be used to prepare high strength wire cutting molybdenum wire, high temperature electric heating element, electric light source material, electric vacuum device and high temperature structural parts, etc. Molybdenum strip is mainly used as an additive to improve the strength and toughness of steel at high temperature.
As one kind of molybdenum products, Molybdenum rod is used for large slab and is the raw material of molybdenum silicide heating element. Fmo-2 is used for silicon controlled wafer, molybdenum tip and other raw materials. Can also be used in powder metallurgy materials, building materials and chemical, petroleum industry. Molybdenum is one of the essential trace elements in plants and is used as trace element fertilizer in agriculture.

Production Process of Molybdenum Metal Bar
Production Process of Molybdenum Metal Bar
Production package after years of practice, we think mainly crystal bar type B molybdenum acid as by roasting process via reduction, suppression of sintered article further deep processing of raw material is better, the current domestic processing filaments article molybdenum manufacturers also continue to use this material as drawn filaments molybdenum strip of raw materials, in addition to the product shape appearance, the content of major elements, such as kalium, sodium, physical properties, such as Ratio, particle size and so on all must meet certain requirements, and maintain a relatively stable.
From the perspective of production methods, the preparation process of molybdenum strip is as follows:
molybdenite concentrate → oxidative roasting → calcining → leaching → ammonium molybdate solution → purification → neutralization crystallization → ammonium polymolybdate solution → dissolution → evaporation crystallization → ammonium secondary molybdate → calcining → molybdenum trioxide → reduction → molybdenum powder → molding sintering → molybdenum strip.
Note that ammonia should be added during leaching and dissolution; Hydrochloric acid should be added during neutralization and crystallization. The gas used in reduction is hydrogen.
Features of Molybdenum Metal Bar
From the physical and chemical properties, ordinary molybdenum strip has various advantages of metallic molybdenum, such as bright and shiny surface, high melting point, high specific gravity, high strength, large hardness, low thermal expansion coefficient, high temperature resistance, good conductivity and so on. Note: Molybdenum strips are silver in color and black when lubricant and oxide coating are retained on the surface.
In terms of appearance and shape, the molybdenum strip is rectangular and cylindrical; From the surface state, molybdenum strip can be alkali washed, polished, polished and polished; From the point of use, molybdenum bar can be divided into conventional molybdenum bar, high temperature molybdenum bar and steel making molybdenum bar.
There are many refractory metal suppliers, but we are one of the best choices for you.
