There are many types of refractory bricks and even more specifications.

Ordinary clay refractory bricks have good thermal shock and are used for general kiln lining. The service temperature is around 1250℃. If it is low-gas clay brick, it can be used in glass kiln and some special kiln lining. The use temperature is more than 1350℃. If the clay refractory bricks are added with rhodochrosite or cordierite, the operating temperature is over 1400℃.

In the case of lightweight clay refractory bricks, the temperature in the holding zone is in the range of 1,000-1,200℃.

High-alumina refractory bricks are used in the high-temperature zone of the kiln lining, in the range of 1300-1400°C. If the temperature exceeds 1400°C, the refractory bricks are used in the lining of the kiln. If the temperature exceeds 1400°C, high alumina refractory bricks or corundum bricks are used. The high aluminum refractory bricks used in the burner part should be mullite refractory bricks or corundum mullite refractory bricks, using temperature 1300-1600℃. That is, high temperature and wear-resistant, fatigue-resistant, flexible and good.

Refractory brick types have a variety of specifications are countless.

Ordinary clay refractory bricks thermal shock is good, used for general kiln lining. The use temperature is about 1250 ℃. If it is low-gas clay brick, it can be used in glass kiln and some special kiln lining. The use temperature is more than 1350℃. If the clay refractory bricks are added with rhodochrosite or cordierite, the operating temperature is over 1400℃.

In the case of lightweight clay refractory bricks, the temperature in the holding zone is in the range of 1,000-1,200℃.

High-alumina refractory bricks are used in the high-temperature zone of the kiln lining, in the range of 1300-1400°C. If the temperature exceeds 1400°C, the refractory bricks are used in the lining of the kiln. If the temperature exceeds 1400°C, high alumina refractory bricks or corundum bricks are used. The high aluminum refractory bricks used in the burner part should be mullite refractory bricks or corundum mullite refractory bricks, using temperature 1300-1600℃. That is, high temperature and wear-resistant, fatigue-resistant, flexible and good.

If the high aluminum brick in the addition of rhodochrosite or cordierite, this special refractory bricks using temperature between 1350-1500 ℃. In the case of lightweight high alumina refractory bricks, they are used in the thermal insulation area. The temperature is between 1200-1350℃. Can only be used for thermal insulation can not be used in the working layer.

Used in the thermal insulation layer or mullite poly light refractory bricks, the use of temperature between 1400-1500 ℃.

If it is alumina hollow ball refractory bricks, can be used as a heat preservation area, but also can be used directly as a working layer, the use of temperature between 1600-1700 ℃.

If it is alkali-resistant refractory bricks, the general alkali-resistant bricks are used at temperatures below 1200℃. If it is magnesium alkaline brick, the using temperature is between 1500-1650℃.

Corundum refractory bricks are used at a higher temperature, above 1700℃. And high strength. Corundum refractory bricks and then into the silicon carbide refractory bricks, not only high temperature resistance, good strength, but also excellent wear resistance.

In short, no matter how high the temperature, choose the right temperature of the refractory brick that saves costs, but also to meet the use.
