【product description】:

Intermediate frequency furnace coil paste Coil paste is also called coil mud, coil coating, which has high strength, high density, high insulation and other characteristics. It is a corundum cement specially designed to protect coreless intermediate frequency furnace coils. The coil cement uses composite sand, special alum, corundum sand, powder organic powder as the matrix, and is premixed by adding an appropriate amount of composite additives, ceramic binders, etc., designed with fire resistance, insulation and operability in mind It plays a good role in protecting the coil of the intermediate frequency induction furnace and the power of the intermediate frequency.
Coil cement is a coating material for the inner surface of coreless inductor coils. It should be evenly spread on the inner surface of the coil with a thickness of about six millimeters. Use between coils for insulation. Add approximately 12% to 14% water to achieve even application. It is recommended that small repairs be done 8 hours before the furnace is built in order to air dry. Large repairs or painting of new coils were performed the day before the furnace was built.
The line cement developed by our company has the following advantages:
1. Protect the induction coil: This product has good high temperature performance. Once the metal liquid penetrates into the furnace lining, it can protect the coil from being dissolved by the metal liquid for a short time; it supports the induction coil to prevent it from deforming during use and removal , Especially for the furnace body with ejection mechanism, it has the function of guiding and preventing the coil from being scratched.
2. Insulation between coil turns.
3. Can be used for new coils or as a repair material for coils.
4. High thermal conductivity.
5. Can prevent the occurrence and expansion of furnace wear
6. Protection of intermediate frequency power supply: The coil cement has good insulation. After coating the coil between the induction coils, it can prevent short circuit or discharge between the coils and cause excessive shock current to burn out the thyristor.
Coil cement has a very good viscosity and is easy to apply. The smooth surface formed on the coil can cushion the expansion and contraction of the working lining. In addition, the coil glue can effectively prevent the leakage of the molten metal and protect the coil from being penetrated by the molten metal.



Coil insulation glue
Coil cement is a coating material for the inner surface of coreless inductor coils. It should be evenly spread on the inner surface of the coil with a thickness of about six millimeters. Use between coils for insulation. Add approximately 12% to 14% water to achieve even application. Coil cement is used for the induction coil of the intermediate frequency coreless induction furnace. It is evenly coated on the surface and ramps, which has a good insulation effect, effectively prevents the coil from igniting due to coil aging and water leakage, and also effectively prevents the molten steel temperature from being too high. Caused by the furnace. It is recommended that small repairs be done 8 hours before the furnace is built in order to air dry. Large repairs or painting of new coils were performed the day before the furnace was built.


Fused corundum-based coil cement
This product is fused corundum-based coil cement, which is mixed with a proprietary particle size ratio. Its main feature is the use of imported pure calcium aluminate cement as a binder, mixed with a proprietary particle size ratio. This product has the characteristics of high insulation, excellent fire resistance and good operability. For the furnace body with ejection mechanism, it can play the role of guiding and preventing the coil from being scratched and scratched.
