We can supply super quality silica bricks for coke oven, which made by composite mineralizer using nanometer technology and scientific controlation. So our silica bricks are with good dense, high RUL, pure color and accurate size. Meanwhile silica brick widely used in glass furnace, blast furnace, hot blast stove etc.
