Conventional safety hazards and precautions for industrial electric furnaces

　　Industrial electric furnace is a kind of high-temperature equipment, which is closely related to fuel oil, gas, electric energy, dust, etc. It is easy to cause fire, burn, explosion, poisoning, electric shock and other accidents. Therefore, compared with general cold processing equipment, industrial furnaces have many more unsafe factors. Generally speaking, the high temperature of industrial electric furnace operation is prone to scalds, burns and burns; high-temperature molten salt and molten metal will explode after encountering water; gas and controllable atmosphere are explosive gases, and oil circuits, fuel tanks and oil depots are all Inflammable and explosive facilities, if used improperly, explosion and poisoning accidents will occur; the safety protection device of the electric furnace fails, and electric shock will occur after contact; the cyanide in the cyanide furnace is highly toxic; the nitrate furnace is heated above 550 ℃. Spontaneous combustion occurs; nitrate will explode after being combined with charcoal and carbon black.

　　The repair environment of industrial electric furnaces is poor. Many repairs are carried out in the furnace. The space is very crowded, the natural light is insufficient, and the ventilation conditions are poor. Workers are not only exposed to dust during operation, but sometimes directly corroded by high temperature, smoke, toxic gases and chemical materials. Some furnaces (such as cupolas) are as high as 10m-20m. Due to the narrow site of the furnace body, the repair work is high-altitude three-dimensional and multi-layer operation, which is very dangerous. Therefore, when operating and repairing industrial furnaces, we must pay great attention to safety issues. Especially when organizing emergency repairs or hot repairs of industrial furnaces, we should pay more attention to the unfortunate accidents that may be caused by these unsafe factors.
