Introduction to the function of coil glue
Coil cement is a coating material for the inner and outer surfaces of coreless induction coils. The cement layer has excellent insulating properties and can completely replace mica and glass wool cloth, acting as an insulating protective layer between the coil and the furnace lining; it should be evenly coated on the inside and outside of the coil. Sheet, the thickness is about 6 mm, it can be used as insulation between the coils. Add about 12%-14% of water to achieve the uniformity of the painting. The cement layer is located between the coils and the insulation layer, when the ambient temperature is very low (<300 degrees="" celsius),="" the="" cement="" layer="" will="" release="" a="" small="" amount="" of="" residual="" moisture="" when="" the="" metal="" liquid="" is="" close="" to="" its="" surface="" occasionally,="" which="" will="" reduce="" the="" insulation="" resistance,="" and="" the="" system="" will="" provide="" early="">
Coil cement is used for induction coils of intermediate frequency coreless induction furnaces. The surface and ramps are coated with cement, which has good insulation effect, can effectively avoid coil fire caused by coil aging and water leakage, and can also effectively prevent molten steel from passing through due to excessive temperature. In the furnace. It is recommended to make minor repairs 8 hours before furnace building and air drying. Major repairs or alterations of new coils should be carried out on the furnace building day.
Coil glue has the characteristics of high strength, high density and high insulation. It is corundum sand glue, which is used to maintain the coil of coreless induction furnace. The coil glue has good viscosity and is convenient to use. The lubricating surface coated on the coil can buffer the working lining The expansion and contraction of the coil. In addition, the coil slurry can effectively avoid the leakage of the metal melt and protect the coil from being broken down by the metal melt.
Advantages of Coil Clay:
1. Insulation between coil turns.
2. The new coil can be coated or used as a correction material for the coil.
3. High thermal conductivity.
4. The occurrence and expansion of penetration can be largely avoided.
