Classification Method of Refractory Materials

According to the classification of chemical properties, it can be divided into acid refractory materials, alkaline refractory materials, and neutral refractory materials.

According to the main mineral chemical composition of refractory materials, it can be divided into siliceous refractory materials, aluminosilicate refractory materials, magnesia refractory materials, magnesium spinel refractory materials, magnesium chromium refractory materials, magnesium dolomite refractory materials, and dolomite refractory materials. Materials, carbon composite refractory materials, high aluminum refractory materials, chromium refractory materials, zirconia refractory materials, etc.

According to the type of supply, it can be divided into two types: fixed refractory materials and unshaped refractory materials.

According to the different classifications of refractory materials, they can be divided into ordinary/high-grade/special grade/super refractory materials. Those that can withstand temperatures of 1580~1770℃ are called ordinary refractory materials. Those that can withstand high temperatures of 1770~2000℃ are called advanced refractory materials. Those that can withstand temperatures of 2000~3000℃ are called advanced refractory materials. The temperature above 3000℃ is called super refractory material, and the temperature above 3000℃ is called super refractory material.

According to the classification of bulk density, it can also be divided into light/heavy refractory materials.

According to different performances and sizes, it can be divided into standard type/ordinary type/special type/special type refractory materials, etc.

Classification according to the chemical composition of refractory materials is the most common classification of refractory materials.
