1. The molten material should be clean, boring and oil-free, in order to build the sintered layer of the furnace wall.
2. The first few furnaces prevent high-power transmission and smelting. A large electromagnetic stirring force will occur at high power, and the sintered layer of the experimental electric furnace lining that has not yet been fully sturdy will be washed away.
3. The iron should be light, and the iron should be thrown evenly. It is easy to damage the thin sintered layer by touching the wall of the experimental electric furnace, which is costly and affects the life of the lining. The average iron addition equalizes the furnace temperature to avoid crusts.
4. In the application, the slag should be diligently slag. The melting point of the experimental electric furnace slag is higher than the melting point of the molten material. The slag crust can not be contacted with the solution, and the bottom of the melting hard lining is subject to high temperature corrosion.
5. The new experimental electric furnace is continuously smelted as much as possible to avoid cracks caused by intermittent melting and cold. Generally continuous smelting for 1 week.
6. Try to avoid high temperature melting during the smelting process.
7. Avoid overheating the lining.
8. When it is necessary to stop the furnace for a long time due to malfunction or the like during use, the molten iron in the furnace should be emptied.
9. Use a clean charge as much as possible in the new furnace.
10. Maintain and maintain the experimental electric furnace equipment. During the use, pay attention to the condition of the furnace.
11. When the furnace is cooled, the empty furnace should be cooled. At the same time, the furnace cover should be covered to make the furnace lining uniform even when cooling, thus ensuring the service life of the furnace.
