Generally speaking, the high temperature of industrial 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 the electric furnace-type industrial furnace is 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 Spontaneous combustion will occur at temperatures above 550°C; nitrates will explode after being combined with charcoal and carbon black.

The repairing environment of industrial 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 crossing and multi-layer operations, which is very dangerous. Therefore, when operating and maintaining industrial furnaces, industrial furnaces must pay great attention to safety issues. Especially when organizing industrial furnaces, we must attach great importance 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.
