Common functions of coil cement of intermediate frequency furnace

The intermediate frequency furnace is now a commonly used induction heating equipment in the machinery industry, and the coil of the intermediate frequency furnace is the key component of the intermediate frequency furnace. Regarding the maintenance of the intermediate frequency furnace coil, the editor believes that the coil cement of the intermediate frequency furnace plays a better role. Coil glue not only plays a role of insulation, but also can enhance the strength of the coil, reduce noise, etc. The following editor summarizes the role of the coil glue of the intermediate frequency furnace as follows, for your reference.

1. After the coil of the intermediate frequency furnace is wrapped with the insulating material mica and glass cloth, it is then smeared outside the intermediate frequency furnace coil - a layer of coil glue, which completely wraps the inductor coil of the intermediate frequency furnace.

2. After the intermediate frequency furnace coil is modified with glue, it needs to be dried. The thickness of the modified coil glue is generally 10-15mm. The thermal conductivity of the coil glue material is high, so there is no need to worry that the relatively thick layer of glue will affect the heating of the intermediate frequency furnace. Function.

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 degrees Celsius). If there is metal liquid close to its surface, the cement will release a small amount of residual water, which will reduce the insulation resistance. The system provides early warning.

4. The coil cement of the intermediate frequency furnace uses the cement itself with a refractoriness higher than 1800 degrees Celsius. If there is metal liquid leaking to its surface, the cement can provide a protective barrier for the coil. When the intermediate frequency furnace alarms, the cement layer can provide A certain time to deal with incidents and reduce the phenomenon of string furnaces.

5. Coil cement of intermediate frequency furnace For furnaces with bottom top-out, the cement is made into a tapered shape, which is easy to eject the furnace lining material, avoids the conflict between the furnace lining material and the coil, and uses its strength to control the coil. It is fixed to avoid the deformation of the coil during the use, construction and dismantling of the furnace, and prolong the service life of the intermediate frequency furnace coil.

6. The coil and mortar layer of the intermediate frequency furnace are used as the refractory lining of the furnace. Although the one-time cost is high and the construction period is long, its service life can be the same as that of the coil, and it can also be partially repaired, so the intermediate frequency is reduced as a whole. Furnace building cost.
