Dense fused alumina is fused in the electric arc furnace with the industrial alumina as the raw material.
It is characterized by acid and alkali resistance, good wear and corrosion resistance, volume stability. It is mainly used for metallurgy, ceramics, chemical industry, etc.
It is the aggregate of producing Blast Furnace Troughs and castables and high quality raw material to produce various corundum products.
