  • 1.Preferable in a double chamber furnace with heating chamber and oil cooling chamber. A middle door between the heating chamber and oil cooling chamber to obtain vacuum sealing, which is not affected by quenching oil and can be cooled by gas;

    2.In order to gain superior heat treatment uniform heating performance and heat preservation performance in a large range from low temperature to high temperature, heaters are set up on the upper and lower sides to realize zone control;

    3.After the processing materials are transported to the furnace through the internal loading fork, all actions are automatically controlled by PLC from the start of vacuum exhaust to the completion of heating and cooling;

    4.Furnace operation by panel (touch screen) to realize miniaturization of control cabinet, and operation instructions and partial operation conditions can be confirmed through touch screen interface;

    5.The heating indoor surface is covered with molybdenum plate, which can meet various process requirements and realize bright tempering process.
