Introduction of Insulation of Coil Clay

The intermediate frequency furnace will generate slight vibration during operation, which will cause the coil to vibrate and produce tiny cracks, which will reduce the service life and quality of the intermediate frequency furnace lining. This requires coil cement to fix and protect the coil. The coil cement design can properly keep the furnace warm , prolong the temperature in the furnace. The high temperature of the coil and the circulating water will produce patina, which will make the wall of the coil thinner. The coil cement can protect the coil and prolong its service life.

Fire resistance, operability and insulation are considered in the design of the coil cement. The coil cement adopts imported high-quality calcium-aluminum refractory cement as a binding agent, which greatly improves the fire resistance and high temperature strength, and plays a role in protecting and preventing the coil from catching fire. the service life of the coil.

The characteristics of composite coil cement are excellent thermal insulation performance, and it is widely used in refractory materials. So, what is the insulation performance of coil cement?

The 8-15mm coil clay layer has excellent insulating properties after drying, and its excellent insulating properties can completely replace mica and glass fiber cloth. Mica and glass fiber cloth also have excellent insulating properties and can be used as coils and furnace linings. In addition, the thermal conductivity of the coil cement layer is high, so there is no need to worry that the thick coil cement layer will affect the heat transfer between the furnace linings.

The coil cement layer is located between the coil and the insulating layer. Generally, when the ambient temperature is very low below 300 degrees Celsius, occasionally molten metal penetrates its surface. The fire resistance of the cement itself above 1800 degrees Celsius can also be used for The coil provides a protective barrier. When an alarm occurs, the coil glue can provide a certain accident handling time, which can effectively protect and prolong the service life of the coil.
