One. Molybdenum rod manufacturing processes

Molding, sintering, drape forging, machining.

Two. Classification molybdenum rod

Material Category:

1, pure molybdenum rod: molybdenum content greater than 99.95%.

2, high temperature molybdenum rod (lanthanum molybdenum alloy bar): lanthanum containing 0.4 to 1.2% molybdenum content of impurities outside the margin.

3, TZM Molybdenum rod: 0.4 ~ 0.6Ti, 0.07 ~ 0.12Zr, 0.01 ~ 0.05C.

Surface state by Category:

A sintered molybdenum rod: silver gray metallic luster surface.

2, forging molybdenum rod: the surface layer of oxide surface was black.

3, car light Molybdenum rod: surface with a metallic luster, smooth rough.

4, polished molybdenum rod: silver gray metallic luster, smooth surface, the size of the error is small.

Three. Molybdenum rod surface oxide removal method

1, has the characteristics of molybdenum products easily oxidized. To be removed when the oxide weight, with a strong acid (hydrofluoric acid, nitric acid, hydrochloric acid, etc.) handling, please pay attention to the operation.

2, mild oxide abrasive cleaners use to add, with a soft cloth or sponge to wipe, then wash with warm water.

Four. Molybdenum rod packing

High moisture molybdenum rod required a separate paper packaging wrapped with foam, wooden box on the right, you must fill the extra gap to prevent vibration occurring in transit, damage to the product

Fifth, the use of molybdenum rod

1 for the manufacture of vacuum devices and electric light source parts

2. Suitable for processing ion implantation Parts

3 for high temperature heating elements and temperature structural parts

4, at 1300 ℃ molten glass in the glass industry as a furnace and refractory fiber electrode, long life

5 rare earth industry as an electrode
