Introduction
The Brother Furnace vacuum annealing furnace is composed of a sealed furnace body, heating chamber, vacuum system, water-cooling unit, electrical control system, and power supply system. The heating chamber can be configured with either graphite or metallic materials, depending on specific process requirements. The electrical control system is equipped with a PLC and a programmable temperature controller, allowing for fully automatic, semi-automatic, and manual operation modes, ensuring flexible and user-friendly operation. During the heating process, the furnace can operate under a vacuum environment or with an introduced protective atmosphere.
