The operating temperature range of commonly used firebricks
Refractory bricks of common clay heat shock well, used for general kiln lining. The operating temperature is about 1250℃. If it is a low gas clay brick, it can be used in glass kilns and some special kiln linings. The operating temperature is above 1350℃. If andalusite or cordierite is added to clay firebrick, the use temperature is above 1400℃.
If it is a light clay firebrick series, the temperature used in the insulation area is in the range of 1000-1200℃.
High-aluminum refractory brick is used in the high-temperature zone of the lining of the kiln, and the use area is in the range of 1300-1400℃. If it exceeds 1400 ° C, it is necessary to use high-alumina refractory brick or corundum brick to resist spalling. The high-aluminum refractory brick used in the burner part should be mullite refractory brick or corundum mullite refractory brick, and the use temperature is 1300 ~ 1600℃. That is, it is resistant to high temperature, wear resistance, fatigue resistance and flexibility.
