Do you know these things about refractory materials?

Zhengzhou sunrise refractory materials have a wide variety of refractory materials. Let's talk about it today. According to the main composition of mineral chemistry, refractory materials can be divided into six categories.

1. Siliceous products, such as silica bricks, fused silica products.

2. Silicon-aluminum products, such as clay bricks, semi-silica bricks, high-alumina bricks, etc.; refractories with alumina and silica as the basic chemical composition can usually be divided according to the content of alumina and silica in the product: Siliceous products (silica greater than 93%), semi-silica products (alumina accounted for 15 to 30%), clay products (alumina accounted for 30 to 48%), high alumina products (alumina accounted for 48 to 90%) ) and corundum products (alumina greater than 90%).

3. Magnesia, magnesia and dolomite products, such as magnesia bricks, magnesia-aluminum bricks, magnesia-chrome bricks, dolomite bricks, etc. 4. Carbonaceous products, such as carbon bricks, graphite clay products, etc.

5. Zirconium products, such as zircon bricks, zirconium mullite bricks, zirconium corundum bricks, etc.

6. Special refractory products, such as pure oxides, carbides, nitrides, borides and other products. In addition, the refractory material can be further classified into a sintered product, a fused cast product, a melt blown product, and the like according to a sintering process.
