Introduction of Refractories for Glass Industry

The glass industry is one of the important application domains of refractory materials. It’s mainly applied in the glass furnace construction. High temperature and corrosive gases can cause serious damage to the glass furnace in the process of glass production. Therefore, refractory materials are widely used in the manufacturing and maintenance of glass furnace. The refractory materials used in glass furnace mainly include fused cast refractories, sintered magnesia refractories, sintered silica refractories and sintered fireclay refractories.

AGRM is one of the main refractory material production enterprises in China, which is devoted to the production and innovation of various refractory materials. Our refractory material products are widely used in various industries including metallurgical, petrochemical, steel, cement, and glass. Our products have been sold far to Europe, North America, Southeast Asia, Oceania and many other countries and regions.

Float Glass Furnace

Compared to other glass furnaces, there is not much difference in structure between float glass furnaces. However, in terms of scale, the scale of float glass furnaces is much larger. They are the largest type, both with regard to dimensions and to the overall melting output. These furnaces are close to the limit of constructive possibilities. Furnace capacities are usually between 600 – 800 t/d. Of course smaller units with 250 t/d are as possible as larger units up to 1200 t/d. Although float glass furnaces and other glass furnaces are different, they still have similarities in their structure. The float glass furnaces mainly includes: feeding system, melting system, heat source supply system, waste gas and waste heat utilization system, smoke exhaust and gas supply system, etc.

Float glass furnaces are especially designed for the production of soda lime glass. The requirements concerning glass quality are much stricter and differ from those for container glass. Float glass furnaces are widely used in the current production of building materials, and fused zirconia corundum AZS is an irreplaceable core material for them. The following is an example of refractory materials used in float glass applications.
