Development Trend of Refractory Materials for Glass Furnace
The development of refractories for glass furnaces in China will continue to focus on the life of glass furnaces, the quality and cost of glass products, energy consumption and environmental protection. In other words, the main problem faced by refractories for glass furnaces is the development of low-temperature melting. That is, with the application of glass furnace oxygen-enriched combustion, full oxygen combustion, arsenic-free material melting process and electric melting technology, will put forward higher requirements for refractory materials, especially cast refractory materials. The author believes that the development trend of refractory materials for glass furnaces in China should be shown in the following three aspects.

Important difference between high alumina brick and clay brick
The main difference is in the aluminum content. The aluminum content of clay brick is 35%-48%, and the aluminum content of high alumina brick is above 48%. High alumina brick according to the different aluminum content is divided into a high alumina brick, two high alumina brick, three high alumina brick and so on.

Application of refractory materials
Special materials often used are AZS bricks, corundum bricks, directly bonded magnesia chrome bricks, silicon carbide bricks, silicon nitride bonded silicon carbide bricks, nitrides, silicides, sulfides, borides, carbides and other non-oxide refractories; Refractory materials such as calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide. Often used insulation refractory materials are diatomite products, asbestos products, insulation board, etc. The unshaped refractory materials often used include furnace charge, ramming material, castable, plastic, refractory mud, spray paint, projection material, paint, light refractory castable, gun mud, etc.
