by

Refractory spray coating materials belong to the category of amorphous materials in refractory materials. They can be lightweight, heavy, or semi-heavy. Lightweight Refractory Spray Coating Lightweight refractory spray coatings serve as thermal insulation and are used as insulation layers. For small areas, they can be applied directly. Because of their short application time, lightweight spray … Read more

Several Commonly Used Refractory Spray Coatings and Their Application Methods

by

The material composition of refractory spray coatings is basically similar to that of similar refractory castables. The difference lies in the smaller critical particle size of the refractory aggregate, typically 3-5 mm, and the application method is spraying. The combined amount of refractory powder, ultrafine powder, and binder is relatively high, generally 35-45%. Spraying is … Read more
