Advantages of molybdenum grinding wheels
Such a circle withstands considerable mechanical loads at temperatures above 1000 °C. It is characterized by heat resistance, heat resistance and corrosion resistance. It is resistant in many aggressive environments, solutions of concentrated alkalis and acids - hydrochloric, H2 SO4, HF. Molybdenum and its alloys have a high modulus of elasticity and an insignificant coefficient of thermal expansion. Since this metal is almost half the weight of tungsten, Mo has a higher specific strength up to 1370 °C. Titanium-molybdenum alloys can easily withstand heat up to 1500 °C. Molybdenum circle grades of MF, MS, MK (molybdenum alloyed with silicon) operated at t ° above 2000 ° C. Molybdenum circles, molybdenum with silicon-alkaline additive are characterized by high t ° recrystallization and high bending strength and tensile strength in the annealed state. Cobalt alloying increases the ductility of annealed molybdenum.
| Length, mm | Diameter, mm | Density, grams/cm2 | Hardness, HB | Specific resistance, Ω *cm |
|---|---|---|---|---|
| up to 1000 | 3-110 | over 10.2 | over 120 | 6.63*10-6 |
Disadvantages
The main disadvantage is the significant cost of production. Molybdenum is quite a rare metal, it is difficult to isolate in its pure form, it is refractory, difficult to process, it is not ductile at low temperatures. It adds hardness to alloys, but it also increases the brittleness of the metal. Pure molybdenum is much heavier than iron and steel.
Applications
The scope of application of molybdenum wheel is associated with its heat resistance and resistance in corrosive environments.
1. Nuclear power and aerospace industries.
2. Industrial chemistry.
3. Heating elements of high temperature electric furnaces.
4. Parts of vacuum tubes.
5. Press molds for hot working, electrodes, sintering of special ceramic mass.
6. Smelting of heat-resistant rare earth metals.
