The sintering temperature of high aluminum brick depends on the raw material. Too high sintering temperature will deform the brick, and too low sintering temperature will have low strength of high aluminum brick, and not wear, easy to peel.

The most difference between the two is the difference in the use of temperature areas, the general static industrial kiln lining construction can be ordinary refractory mortar, or phosphate refractory mortar, and the dynamic kiln lining is best to use PA80 refractory glue, because of the dynamic mechanical pressure and kiln stress, to prevent the brick drop out of the rotation process.

What kind of refractory castable is suitable for the 1300℃ furnace lining? it is based on the different lining atmosphere of different furnace types, no matter what material is selected, the ultimate purpose is to save energy and reduce consumption, to achieve the use effect and long service cycle.

The firing temperature of the brick process between the high strength alkali brick and fire clay brick is the same, but the the raw material process is not the same, the sintering temperature of the sintering time is not the same. High-strength alkali-resistant brick has strong alkali resistance, while clay brick is a slightly acidic product with strong resistance to acid erosion.

Low cement castable and traditional castable is very different, mainly in the difference between the middle and final strength, the traditional castable in the middle strength is not good, but low cement castable is far better than the traditional refractory castable, not only because the cement content is low, and have less calcium content, but also the use of ultrafine powder technology, so that the castable is in a reasonable proportion of particles distribution. Moreover, the final strength and middle strength of castable also are further improved.

The chimney lining is made of light acid-resistant castable, which has strong air tightness, and does not require light and heavy layers. The two-layer material construction reduces the thickness of the lining and improves the thermal insulation performance.
