Intermediate frequency furnace coil mortar

Intermediate frequency furnace coil mortar is also called coil mortar and coil coating. It has the characteristics of high strength, high density, and high insulation. It is a corundum mortar specially designed to protect coreless intermediate frequency furnace coils. The coil mortar is made of composite sand, special alum, corundum sand, powdered organic powder as the matrix, and premixed with appropriate amount of composite additives, ceramic bond, etc., and the design takes into account the fire resistance, insulation, and operability. Play a good role in protecting the intermediate frequency induction furnace coil and intermediate frequency power supply.

Coil paste is a coating material used on the inner surface of coreless inductor coils. It should be evenly applied to the inner surface of the coil with a thickness of about six millimeters. Used between the coils can play the role of insulation. Add approximately 12%-14% of water to achieve uniformity of application. It is recommended that minor repairs should be carried out 8 hours before the furnace is built to allow it to air dry. Major repairs or painting of new coils are carried out one day before the furnace is built.

The line mortar developed by our company has the following advantages:

1. Protect the induction coil: This product has good high temperature performance. Once molten metal penetrates into the furnace lining, it can protect the coil from molten metal in a short period of time; it supports the induction coil to prevent it from deforming during use and removal of the furnace lining. , Especially for the furnace body with ejection mechanism, it has the function of guiding and preventing the coil from being scratched.

2. Insulate between the turns of the coil.

3. You can apply new coils or make coil repair materials.

4. High thermal conductivity.

5. It can limit the occurrence and expansion of furnace wear

6. Protection of intermediate frequency power supply: Coil paste has good insulation. After the paste is coated between the turns of the induction coil, it can prevent the short circuit or discharge of the coil from generating excessive impulse current to burn the thyristor and so on.

The coil glue has good viscosity and is very convenient to apply. The smooth surface formed on the coil can cushion the expansion and contraction of the working lining. In addition, the coil mortar can effectively prevent the leakage of molten metal and protect the coil from the breakdown of molten metal.
