Silica refractory brick are mainly used in the coking chamber and the combustion chamber of coke oven, steel-making open-hearth regenerator and the sediment chamber, soaking furnace, glass furnace tanks. The silica brick refractories are also used high-temperature load-bearing parts of the hot blast stove and acid open-hearth roof. NR general grade silica bricks are most often used in the iron & steel industry, while the super grade to be used on the glass industry. The silica brick refractories have a main characters of high dense( good for thermal conductivity),high RUL and high tridymite content, lower true density, low expansion, low creep and low residual quartz, accurate size tolerance, purity colors and luster forming good appearance.
