Supply Low Price Furnace Liner Refractory Silica Ramming Mass For Construction Of Various Kilns Lining
Silica ramming mass is made of quartz (SiO2) refractory raw material as aggregate and a certain proportion of powder, binders and additives, which can be used?for construction of lining of various kilns. The silicon ramming mass introduced today is used in the working layer of the tundish, and the service life can be up to 30 hours after the overall casting, which is generally applicable to small and medium-sized tundish.
