In the application practice of the induction melting furnace in the forming furnace lining, it is found that many users adopt a multilayer protective structure of mica sheet insulation layer, asbestos cloth insulation layer, and stainless steel wire mesh alarm layer. Construction is tight, so coil coatings are recommended.

The coating protective layer of the induction coil is made of refractory high alumina cement mixed with water-soluble strong colloidal powder. The protective layer can be used for a long time after one-time application. The protective layer has excellent thermal insulation properties, which can maintain a large temperature gradient between the melt and the coil in the furnace, maintain the coil's vertical concentricity and the coil turn distance, effectively prevent the coil from deforming, and prevent leakage from melting. Damage coil. As a result of the elimination of asbestos cloth, workers' silicosis is avoided and environmental protection is also beneficial. It can be expected that with the wide application of the fast-installation molding furnace lining, it will bring a profound change to the furnace lining of the induction melting furnace.
