How to ensure the service life of intermediate frequency furnace
Medium frequency furnace lifeIt is not only affected by the production efficiency of the intermediate frequency furnace, but also affected by the bottom and wall of the intermediate frequency furnace. How to increase the life of the intermediate frequency furnace should pay attention to the following points.
1. The molten material should be clean, boring and oil-free, so as to build the sintering layer of the furnace wall.
2. The first few furnaces prevent high-power power transmission and smelting, and high-power electromagnetic stirring force will occur, which will scour and lose the sintered layer of the furnace lining that is not completely strong.
3. Add iron lightly and throw iron evenly. Touch the furnace wall and easily damage the very thin sintered layer, resulting in scattered consumption and affecting the life of the furnace lining. Average iron addition can equalize furnace temperature to avoid junction
4. In the application, the slag should be fished frequently. The melting point of the slag is higher than that of the molten material. The molten material of the slag crust cannot contact with the solution, and the bottom of the melting hard furnace lining crucible is corroded by high temperature.
5. The new intermediate frequency furnace shall be smelted continuously as much as possible to avoid cracks caused by intermittent smelting. Generally continuous smelting for about a week.
6. Try to avoid high temperature smelting in the smelting process.
7. Avoid overheating of the furnace lining.
8. When the furnace needs to be shut down for a long time due to faults and other reasons during use, the molten iron in the electric furnace should be emptied.
9. The new medium frequency electric furnace as far as possible the use of clean charge.
10. Medium frequency furnace equipment maintenance and maintenance. During use, pay attention to observe the condition of the intermediate frequency furnace.
11. Medium frequency furnace cooling should be empty furnace cooling, at the same time should cover the furnace cover, so that the lining in the cooling up and down uniform, so as to ensure the service life of the medium frequency furnace.
