Features and Benefits of Coil Clay

Application of coil cement: The induction coil of the intermediate frequency coreless induction furnace is coated with a coil insulating cement layer. Compared with the insulating materials such as mica and glass fiber cloth commonly used in the induction circuit, the use of coil insulating cement has the following advantages:

1. After drying, the coil insulating mastic layer with a thickness of 8-15mm has good insulating properties, and can completely replace mica and glass wool cloth as an insulating protective layer between the coil and the furnace lining; the thermal conductivity of the mastic material is high, and it is not necessary to Worried that a relatively thick layer of cement will affect the 3-layer junction of the hot-face lining;

2,Coil ClayBetween the bathroom coil and the thermal insulation layer, under normal circumstances, the ambient temperature is very low (<300 degrees="" celsius,="" and="" the="" coil="" 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="" alarms.="">

3. The use of coil mortar itself has a refractoriness higher than 1800 degrees Celsius. When there is occasional leakage of metal liquid to its surface, the mortar can provide a protective barrier to the coil. When an alarm occurs, the mortar layer can provide certain event handling. event;

4. For furnaces with top-out type, the coil cement is made into a tapered shape to avoid friction between the furnace lining and the coil, and at the same time use its strength to fix the coil, which avoids the use and construction of the coil. The deformation during the dismantling process prolongs the service life of the coil.

5. The coil and the cement layer are used as the permanent fire lining of the furnace. Although the one-time cost is higher and the construction period is longer, its service life can be the same as that of the coil, and it can also be partially repaired, so the overall cost is reduced. Furnace cost.

6. Coil glue has good viscosity, and it is very convenient to apply. The smooth surface formed on the coil can buffer the expansion and contraction of the working lining. In addition, the coil glue can also effectively prevent the leakage of molten metal.
