x The flat-panel electric heater has a simple and fashionable design, and the thin-film electric heater can also be used for stand-up or wall-hanging. High-efficiency electric heating film is used for heat generation and convection heat dissipation.Differences in vacuum heat treatment between aerospace blanks and parts The intelligence is relatively high, most of them have functions of constant temperature, timing, negative ions, infrared radiation heating, etc., and a drying rack is provided to facilitate drying clothes. Step shaft vacuum quenching heat treatmentHigh thermal efficiency, relatively energy saving, no noise and no light consumption pollution. It has three functions: function switch, temperature adjustment, and timing switch. The price is relatively high.High speed steel vacuum heat treatment
