Various Types And Uses Of Refractory Materials

There are various types and uses of refractory materials, and it is necessary to scientifically classify them for scientific research, rational selection, and management. There are many classification methods for refractory materials, including chemical property classification, chemical mineral composition classification, production process classification, material morphology classification, and other methods.
1. According to the degree of fire resistance:
Ordinary refractory materials: 1580 ℃~1770 ℃
Advanced refractory materials: 1770 ℃~2000 ℃
Special grade refractory material:>2000 ℃
2. According to the different shapes and sizes of the products:
Standard type: 230mm × 114mm × 65mm;
No more than 4 measuring scales, (size ratio) Max: Min<4:1;
Irregular shape: no more than 2 concave corners, (size ratio) Max: Min<6:1;
Or there may be an acute angle of 50-70 °;
Specificity: (Size ratio) Max: Min<8:1;
Or no more than 4 concave corners; Or there may be an acute angle of 30-50 °;
Special products: crucibles, vessels, tubes, etc.
3. According to the manufacturing method, refractory materials can be divided into:
Burnt products, unburned products, amorphous refractory materials
4. Classified by material chemical properties:
Acidic refractory material, neutral refractory material, alkaline refractory material
5. Classify according to chemical mineral composition
This classification method can directly characterize the basic composition and characteristics of various refractory materials, and is a common classification method in production, use, and scientific research, with strong practical application significance.
