Rods are produced of pure molybdenum MCh, MChVP grades (vacuum-melted) and of TsM2A (zirconium and/or titanium additives), TSM4 (zirconium and nickel additives) and other molybdenum-based alloys.
Production
Molybdenum rods are forged (pressurized). Square billets with the side size not exceeding 40 cm serve as the primary raw material for production. Forging is made with a swaging machine. Due to molybdenum properties its pressurizing is made after heating. Forging is made in several stages, each stage for making molybdenum rods of a smaller diameter.
Rods should comply with requirements of GOSTs and TC such as GOST 17432-72, TC 11-77 (Яе0.021.057 ТУ), TC 48-19-203-85 etc.
Application
Molybdenum rods are used as heaters of high-temperature electric furnaces. Such heaters should work in hydrogen atmosphere, inert gas and vacuum.
Also molybdenum rods are applied for making bushings of vacuum-tube devices. Molybdenum bushings can conduct higher currents (e.g., bushings of glass valves.
