Where Refractories Are Used
Industry
Glass
Refractories in the glass industry line the melting tank, the superstructure, the working end and forehearth, the throat and the regenerator. Different furnace types take different materials, in fused, siliceous and magnesia groups: silica, clay, high alumina, sillimanite, mullite, fused mullite, zirconia-corundum, fused corundum and zirconium-containing refractory bricks.

Cement
Refractories in cement plants line the preheater, the calciner and tertiary air duct, the rotary kiln from the kiln inlet through the safety, transition and burning zones to the kiln outlet, the kiln hood and burner, and the grate cooler. RISING's kiln configuration tables assign alkali-resistant bricks and castables to the preheater system, silicon mullite, magnesia spinel and magnesia-chrome bricks to the kiln zones, and low-cement and steel-fiber castables to the kiln mouths, hood and cooler.
