In order to protect and provide the service time of box type electric furnace, Jinan box type electric furnace manufacturer introduces some small matters of box type electric furnace
(1) Regularly check the connection of electric furnace and controller.
（2）電爐和操控器有必要在相對濕度不超越85%，沒有導電塵埃，爆 炸 性氣體和能損壞金屬絕緣以及電子元件的腐蝕性氣體的場所作業。
(2) It is necessary for electric furnaces and controllers to work in places where the relative humidity does not exceed 85%, and there is no conductive dust, explosive gas and corrosive gas that can damage metal insulation and electronic components.
(3) The operating temperature of the controller is limited to 0-50 ℃.
(4) When the electric furnace and controller are used, the rated power shall not be exceeded, and the furnace temperature shall not exceed the high operating temperature. It is forbidden to load the wet workpiece into the furnace. The heated workpiece rich in ultra-high moisture shall be dried in advance.
(5) Adhere to the cleaning of furnace bottom, timely remove the metal oxides, slag and impurities in the furnace, and be careful when loading and unloading the workpiece to prevent damaging the silicon carbide rod.
(6) The silicon carbide rod should be placed in a dry place to prevent the aluminum head from moisture degeneration. If it is found that some rods are white and some are dark red during operation, it is clarified that the resistance changes of each rod are different. It is necessary to replace the rod with similar resistance value and use it again from the beginning in the future.
(7) Silicon carbide rod is the recrystallized product of silicon carbide. Alkali, alkali metal, sulfuric acid and boron compounds can corrode it at high temperature. Water vapor has a strong oxidation effect on it: hydrogen and gas rich in hydrogen will differentiate silicon carbide rod at high temperature. It is necessary to pay close attention to it during application.
