中频电炉在开炉前必需要对电气装置、水冷却体系、感应器铜管等进行检查，只有在这几个装置完好的情况下才能开炉，确保热处理的安全性，否则禁止开炉;确定专门负责送电和开炉的人员，并且负责人员不得擅自离开岗位，工作期间必需对感应器和坩埚的外部情况进行监管，以防止有人在送电后触碰感应器和电缆，影响中频电炉的正常作业或发生安全意外。
Before opening the medium frequency electric furnace, it is necessary to inspect the electrical equipment, water cooling system, inductor copper pipes, etc. Only when these equipment are in good condition can the furnace be opened to ensure the safety of heat treatment, otherwise it is prohibited to open the furnace; Determine the personnel responsible for power transmission and furnace operation, and the responsible personnel shall not leave their positions without authorization. During the work period, it is necessary to supervise the external conditions of the sensors and crucibles to prevent anyone from touching the sensors and cables after power transmission, affecting the normal operation of the medium frequency electric furnace or causing safety accidents.
2、开炉后的注意事项
2. Precautions after opening the furnace
中频电炉开炉后，在进行装料时，应对炉料内进行检查，避免混入易燃易爆等有害物品。为了防止结盖现象的出现，严禁在钢液中直接加入冷料和湿料，以及在熔化液充满到上部后不得加入体积较大的块料;为避免出现爆炸意外，必需确保浇注场地和炉前地坑无积水，无障碍物;而在进行浇注时需两人配合进行，而剩余的钢液只能倒在在制定地点，不能随处乱倒。
After the medium frequency electric furnace is turned on, during charging, the furnace material should be inspected to avoid mixing with flammable and explosive substances. In order to prevent the occurrence of capping, it is strictly prohibited to directly add cold and wet materials to the molten steel, as well as not to add larger bulk materials after the molten liquid is filled to the upper part; To avoid explosion accidents, it is necessary to ensure that the pouring site and the pit in front of the furnace are free of accumulated water and obstacles; During pouring, two people need to cooperate, and the remaining steel liquid can only be poured at the designated location and cannot be poured randomly.
