The Manufacturer For Silica Fireclay Since Year 1980:
Refractory SiO2 Silica Fire Clay For Coke Furnace And Steel Furnace Etc.Could Work For 1700 Celsius Degree High Heat.With Quality Assurance High SIO2 Content!
We practice the Chinese national standard of the fireclay serials and accord to the Japanese new technology in this field to produce silica mortar for coke oven. Our main material is natural silica soil that contents 97% SiO2 with desired granularity. The product performance is even better than Japanese silica mortar. we ever supplied this product to Mittal Steel South Africa project, Tata steel india project, Iran national steel project and Brazil coke oven project.
