Refractory materials occupy a crucial position in the glass industry and are key factors to ensure the smooth progress of glass production.
Refractories are widely used in glass melting kiln. For example, silica bricks are often used in the vaults of glass furnaces. Silica brick has the advantages of high softening temperature under load and low thermal conductivity, which can work stably in the high temperature environment of glass melting for a long time, withstand the huge weight of the vault, effectively reduce heat loss, maintain the uniformity of temperature in the melting kiln, and create good conditions for glass melting.
Basic refractory materials such as magnesia brick and magnesia chrome brick have excellent performance in the pool wall of glass melting kiln. They can resist the erosion of glass liquid, especially when melting glass containing more alkaline components. The high temperature resistance and corrosion resistance of these refractories ensure the stability of the pool wall, prevent the leakage of glass liquid, and ensure the normal operation cycle of the glass melting kiln.
Fused refractories are also indispensable in the glass industry. Fused zirconium corundum brick, because of its high purity, high density and excellent resistance to glass washing ability, is widely used in the key parts of glass melting kiln, such as charging port, flow hole and so on. In these parts, the flow speed of the glass liquid is fast and the scouring force is strong, and the electrofused zirconium corundum brick can effectively resist this scouring to ensure the stable flow of the glass liquid and high-quality glass production.
In addition, refractories are also used in glass fiber production. In glass fiber furnaces, special refractory materials are needed to meet the process requirements of high temperature melting and fiber molding. These refractories should not only ensure the high-temperature stability of the furnace, but also avoid adverse effects on the quality of the glass fiber.
In short, refractories play an irreplaceable role in all aspects of the glass industry, and their performance directly affects the efficiency, quality and cost of glass production. With the development of the glass industry, the performance requirements for refractories will continue to improve, prompting continuous innovation and improvement in the field of refractories.
