Medium frequency furnace is currently the most commonly used induction heating equipment in the mechanical industry, the coil of the medium frequency furnace is the key component of the medium frequency furnace, for the protection of the coil of the medium frequency furnace, the small series of Hubei Anaiji believes that the coil cement of the medium frequency furnace plays a very good role, the coil cement of the medium frequency furnace not only plays an insulating role, but also can enhance the coil strength, reduce noise and so on. Haishan electric furnace Xiaobian summed up the role of the coil cement of the intermediate frequency furnace the following points for your reference.
1. After the coil of the intermediate frequency furnace is wrapped with insulating material mica and glass wire cloth, a layer of coil mud is applied to the outside of the intermediate frequency furnace coil to wrap the inductor coil of the intermediate frequency furnace as a whole.
2, intermediate frequency furnace coil paste, need to be dried, paste the thickness of the coil paste - generally 10-15mm, coil cement material high thermal conductivity, do not worry about the relatively thick layer of cement will affect the heating performance of the intermediate frequency furnace.
3, the coil cement layer of the intermediate frequency furnace is located between the coil and the insulation layer, under normal circumstances the ambient temperature is very low (<300°C), if there is a metal liquid close to the surface of the cement will release a small amount of residual moisture, so that the insulation resistance is reduced, the system provides early alarm.
4, intermediate frequency furnace coil mortar using the mortar itself higher than 1800°C refractoricity, if there is metal liquid leakage to its surface, the cement can provide a layer of protective barrier to the coil, when the intermediate frequency furnace alarm, the cement layer can provide a certain accident processing time, reduce the series furnace phenomenon.
5, intermediate frequency furnace coil cement For the furnace with bottom ejection type, the cement is made into a shape with taper, easy to ejection the lining material, avoid the friction between the lining material and the coil, and use its strength to fix the coil, avoid the deformation of the coil in the use and construction and dismantling process, and extend the service life of the intermediate frequency furnace coil.
6, the coil and cement layer of the intermediate frequency furnace as the furnace refractory lining, although the first - secondary cost is high, the construction period is long, but its service life can be the same as the coil, can also be partially repaired, so on the whole reduce the cost of the intermediate frequency furnace building.
