Box Type Electric Resistance Heat Treatment Hardening Furnace
Tips：We have Professional R&D engineer, Customized furnaces as your required is welcome.
This series of electric furnaces is intermittent operation furnaces which can be used in normalizing, annealing,quenching, tempering, hardening and other heat treatments of carbon steel, alloy steel, high-speed steel and other metal parts. Organic liquid can be dripped into cracking atmosphere of the furnace to realize little-oxidizing heating.
1. Adopt mixed furnace lining of ultra-light refractory bricks (0.6/cubic meter) and ceramic fiber, greatly shortening starting heating time and extraordinarily saving energy up to 20%-30%.
2. Specially-designed furnace door and roller sealing, and built-in heating wire ensure excellent furnace door sealing and uniform furnace temperature.
3. Double-thermocouple control: one thermocouple is for testing furnace temperature, and the other one is for over-heat protection.
4. The furnace is equipped with interlock protection device, which can prevent Failure and accident due to misoperation.
5. Adopt intelligent digital temperature-control system, which feature clear reading, conveniently adjusted, high temperature control precision, easy structure, safe and reliable.
