Application:
High aluminum bricks can be used in the following parts:
Glass kiln tube parts: High aluminum bricks are widely used in the lining and exterior construction of glass kiln tubes. Due to the high temperature stability and corrosion resistance of high aluminum brick, it can effectively resist the erosion of glass liquid and other corrosive substances, so as to ensure the stable operation of the kiln.
Glass kiln top: High aluminum bricks can also be used for the top masonry and lining of glass kilns. The kiln top is usually affected by high temperature, high pressure, corrosion and other factors, and the high strength and corrosion resistance of high aluminum bricks can effectively protect the kiln top from the damage of these factors.
