Molybdenum boat in industrial application
Molybdenum boat in industrial application
Molybdenum, English name molybdenum. The density of molybdenum is 10.2 g/cubic centimeter, the melting point is 2610°C, and the boiling point is 5560°C. . Molybdenum is a transition element, which can easily change its oxidation state, and its stable price is +6.
The traditional use of molybdenum boats is mainly used in the iron and steel industry, most of which are briquetted from industrial molybdenum oxide and used directly for steelmaking or cast iron, and a small part is smelted into ferromolybdenum and then used for steelmaking. The content of molybdenum in low-alloy steel is not more than 1%, but the consumption in this area accounts for about 50% of the total consumption of molybdenum. Adding molybdenum to stainless steel can improve the corrosion resistance of steel. Adding molybdenum to cast iron can improve the strength and wear resistance of iron. The nickel-based superalloy containing 18% molybdenum has the characteristics of high melting point, low density and small thermal expansion coefficient, and is used to make various high-temperature components of aviation and aerospace. Molybdenum is also widely used in electronic devices such as electron tubes, transistors and rectifiers.
Molybdenum boat products are widely used in industry. Pure molybdenum wire is used for high-temperature electric furnace, electric discharge machining and wire cutting; molybdenum boat is used to make radio devices and X-ray devices; molybdenum crucible is used for rare earth refining; Molybdenum and molybdenum alloys are resistant to high temperature ablation, and are mainly used in the manufacture of hot runners, gun bores, rocket nozzles, and tungsten wire brackets for light bulbs.
Modern industry is widely used in the use of infrared optical coating, involving the field of coating equipment, including the boat cabin and the boat wings arranged at both ends of the boat cabin, the boat wing is connected with the boat cabin through turning arcs and connecting pieces, and the boat cabin includes a quadrangular pyramid Shaped tank body and rectangular cabin frame, the rectangular cabin frame is arranged on the upper end of the tank body, the opening area of the rectangular cabin frame is smaller than the opening area of the tank body, symmetrically arranged on the rectangular cabin frame along the boat wing direction The slide rail is provided with a cover plate slidingly connected with the slide rail, the two ends of the cover plate are provided with folded edges downward, and the cover plate is provided with a material injection hole and a coating hole. , The structure is reasonable, the structure is stable, it is not easy to deform at high temperature, the raw material is not easy to splash, and it saves raw materials and reduces production costs.
Name: molybdenum boat, riveted molybdenum boat, welded molybdenum boat, folding molybdenum boat, stamping molybdenum boat
Molybdenum and its various alloy materials:
Standard: ASTM B386-91,
Purity: ≥99.95%
Process: hot rolling, cold rolling, alkali washing, shearing, riveting
The purity of the molybdenum boat is over 99.95%. It has good electrical and thermal conductivity, high temperature resistance, wear resistance and corrosion resistance. And there are many types of molybdenum boats.
1. Flat slot boat: suitable for high wettability materials
2. V-shaped groove boat: suitable for materials with low wettability
3. Elliptical tank boat: suitable for materials in molten state
4. Spherical tank boat: suitable for expensive materials such as gold and silver
5. Narrow tank boat: this design can prevent the evaporation material from sticking to the filament clip
6. Aluminum evaporation boat: A layer of aluminum oxide is coated on the surface of the boat body to help the evaporation boat resist particularly corrosive molten materials.
