Box furnace worker safety technology manipulative instrument should be warmed before 8. Check the electrical engineering program tetrafluoroethylene temperature sintering furnace, furnace wire instrument is in good condition. After passing the examination, laboratory analysis furnace, the operator starts transmission. 9. Install, baked preceded power, non-powered operation. 10. Before energizing chamber furnaces should first closing, and then open the control cabinet a button, before the shutdown should first turn off the push-button control panel and then wind up. 11. The monthly clean up various parts (including the lower furnace bottom) of oxide and dirt found that the problem should be repaired. 12. The heat treatment oven, incubator, electric furnace should not exceed the rated temperature. 13. The work is completed, it should organize the workplace, and to explain the situation to take over personnel and equipment. The structure of the series carburizing furnace from the furnace shell, lining, lid lifting mechanism, sealed furnace fan, muffle tank, heating element and electrical control system components. Furnace shell made of welded steel plate and steel. Lining is 0.6g / cm3 high-strength ultra-light saving bricks, aluminum silicate fiber, diatomite insulation bricks and masonry from asbestos saving composite structures. Lid lifting mechanism consists of motor, gear pumps and other components, electric stove, when the lid open, simply press the control button on the box, the lid that is at a rate of 30-70 mm / sec rise. For safety reasons, laboratory furnace, installed in the lift shaft has two travel switch, when the lid rises, the lower limit switch automatically cut off carburizing furnace control cabinet main circuit power supply, the heating element power to stop working, the upper limit switch the lifting shaft rising height restrictions prevent the lift pump rises too high prolapse.
