Industrial furnace is one of the common equipment in industrial production. It is mainly used in heating, smelting, drying, sintering and other processes. The high concentration and accurate control of the temperature and heat source in the furnace make it indispensable in many industrial production processes. one of the devices. Alumina ceramic densely sintered However, in the process of using industrial furnaces, there are also some unsafe factors that cannot be ignored. These factors may lead to equipment failure, personal injury, and even serious accidents such as fires and explosions.The characteristics and working principle of vacuum heat treatment furnaces First of all, it is the control of the temperature in the furnace. Industrial furnaces need to control the temperature during the heating process to achieve safe and stable production. However, if the control system in the furnace fails or is improperly adjusted, the temperature will be out of control, Maintenance of Vacuum Carburizing Furnaces causing the temperature to be too high or too low, causing equipment failure or explosion. In addition, due to the high temperature in the furnace, if the operating door or observation port is opened carelessly, workers may be burned by the heat in the furnace or be burned.Applied Crack Repair Technology of Vacuum Brazing
