vacuum furnace

Vacuum furnace is mainly used for the melting of metal materials (such as stainless steel, nickel-based alloy, copper, alloy steel, nickel-cobalt alloy, rare earth neodymium iron, etc.) under vacuum or protective atmosphere conditions. It can also be used for the vacuum refining of alloy steel and precision casting.
