Copper wire bright well type vacuum annealing furnace

Small pit furnaces mostly use electric heating, and most of them are equipped with special metal muffle tanks. The copper wire bright pit vacuum annealing furnace can be used for gas carburizing, nitriding, carbonitriding, bright annealing and other heat treatments. The copper wire bright pit vacuum annealing furnace is more suitable for the use of electric energy in areas with sufficient power supply, or large pit furnaces that require precise control of the furnace temperature.
