Refractory brick classification, what is breathable corundum brick?
For refractory bricks, some conditions of use are to use the high porosity and high air permeability of the product. At present, the steel mill widely used ladle bottom blowing argon breathable corundum brick, with gas blowing metal, that is, with gas blowing liquid with corundum brick. The use of the same particle size, the use of filler and binder in the sintering process to tightly bond the particles together, so that the product becomes a solid block, and the same size of the particle material determines the shape and size of the pores. If it is necessary to increase the breathability of the product, it is also necessary to add a burn-in additive whose particle size should be the same as the filler size, and the shape should be the same as it.

Application of Refractory Materials in Different Parts of Glass Furnace
The maximum temperature in the melting zone of the glass melting furnace is 1560°C to 1670°C. The safety limit generally depends on the softening point of the glass composition and the silica brick crown. The silica bricks begin to soften and melt at 1620°C. The reason why crowns are built with silica bricks instead of other refractory materials with higher refractoriness is that they have high strength at high temperatures and ablative materials are also compatible with glass, while other refractory materials may produce insoluble stone and other inclusions.

Common Refractory Materials and Selection Factors in Glass Furnace
Refractory glass is a broad concept, its literal meaning can be understood as a kind of glass with fire resistance. According to the different scope of use of refractory glass, it can be divided into building refractory glass: monolithic non-heat-insulating refractory glass, hollow refractory glass, heat-insulating refractory glass, etc. In addition to the refractory glass used in construction, it is used for The glass of various equipment high temperature observation windows: fireplaces, ovens, tin furnaces and other infrared heating equipment.
