used in severe corrosion areas of reinforcing fiberglass furnaces and E-glass furnaces. Typical areas are throats, melter sidewalls, refiner sidewalls, bottom pavings, forehearths and back-up blocks
High-chrome bricks are mainly used in the key parts of the furnace for coal chemical industry, chemical industrial, alkali-free glass fiber and garbage incinerator, ect. Chromium-corundum bricks are mainly used for the lining of carbon soot furnace and copper smelting furnace, the skid rail molten pool of glass furnaces, and tapping platform of rolling mill furnace
