Low cement refractory castable the number of low eutectic phases in the matrix is greatly reduced due to the addition of 1/2-1/15 of normal refractory to cement in the mix. So the fire resistance, high temperature strength and slag resistance will be improved. In addition, the relationship between cement content and refractoriness varies. With the increase of cement content, refractoriness also decreases linearly. On the contrary, the low melt is reduced at high temperature, so that the abrasion and corrosion performance, high temperature bending strength and load softening temperature of the castable have been significantly improved.

Low cement refractory castable advantage：

1. Low porosity and high volume density;

2. The water requirement, volume density and porosity of low cement refractory castable and traditional castable also vary. The strength of the castable varies with the amount of water added.

3. Good intensity of thermal vibration；

4. High refractoriness, high softening temperature under load;

5. Excellent corrosion resistance, low wear rate;

6. Good mechanical spalling resistance and spalling resistance.

This series of refractory castable advantage remarkable. During construction, a certain amount of water is added, and after stirring, it is poured into shape. After curing and baking, it is finally formed. Refractory castable products are rich in variety, high quality and safe to use.

Characteristics of high aluminum castable

1. Cement low of amount reduces the amount of low melting phase in the castable, makes the content of calcium in the castable low, and makes the strength of high aluminum castable increase obviously in the later stage.

2. Low water consumption during construction will increase the density of castable and reduce porosity.

3. High alumina castable not only has high strength at normal temperature, but also has no decrease in strength after medium, moderate and high temperature treatment, and its strength is higher than that of traditional refractory castable.

4. Good volumetric stability at high temperature.

High aluminum castable price is determined according to the height of body density, generally speaking, less burners or low body density of high aluminum, the production of refractory castable will be relatively low, if the body density of high castable, the price will be relatively high.
