ZKTherm vacuum gas quenching furnace is made up of a furnace shell, molybdenum/graphite heating chamber, vacuum system, and cooling system. The heating chamber material is graphite felt. The furnace includes the Vertical type and Horizontal type, and blowing methods include circular blowing and up-down blowing. This furnace can be equipped with a hot stirring fan for low-temperature stirring (Optional: Stirring fan) and can be vented at any temperature (Optional: valve heat exchanger).
This furnace is widely used in aerospace/aviation, weapons, automobiles, electronics, machinery industry, and other fields, and can be used for heating treatment of annealing, tempering, quenching, brazing, etc.
