Several Commonly Used Refractory Spray Coatings and Their Application Methods
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
