Features of High Alumina and Low Cement Castables

High-alumina low-cement castable is a kind of refractory castable made of high-alumina bauxite clinker as aggregate, refractory clay as powder, adding aluminate cement and sodium tripolyphosphate according to the formula ratio. The cement content is less than 8%, which is a commonly used high alumina refractory castables for kiln lining.

First. Physical and chemical indicators of high alumina and low cement pouring:

Second, the characteristics of high-alumina low-cement castables:

1. Good shock resistance. High-aluminum low-cement castables have good shock resistance and can withstand the vibration and impact of equipment during operation.

2. It has good acid and alkali corrosion resistance. Because high alumina bauxite has good acid and alkali resistance, high alumina low cement castables have good acid and alkali resistance.

3. It has good wear resistance. High-aluminum low-cement castables have good wear resistance characteristics, so they can withstand impact and wear during equipment operation.

4. It has good temperature resistance. The refractoriness of high-alumina low-cement castables can reach about 1800 degrees Celsius.

In view of some characteristics of high-alumina and low-cement castables, it is widely used in temperature equipment in metallurgy, the chemical industry, building materials, and other industries.
