Low cement refractory castable is mainly used in metallurgical, petrochemical, mechanical manufacturing, electric power and building materials industrial kilns. Now this refractory castable has replaced the traditional fired refractory as the backing. Low cement castable manufacturing can also be used for heating furnace, heat treatment furnace, electric furnace cover, shaft kiln, rotary kiln, blast furnace iron ditch, ladle, ladle lining.

This series of refractory castable is supplied in the form of scattered dry powder. In construction, clean water is added according to the requirements. After stirring, it can be vibrated or rammed. High temperature performance of low cement castable, high strength, wide range of temperature, basically no shrinkage after high temperature, overcome the previous characteristics of refractory concrete shrinkage. Easy to store, transport and use.

Low cement castable manufacturing is widely used in power plant, boiler, melting furnace, heating furnace, soaking furnace, heat treatment furnace and induction furnace lining different parts. It has the characteristics of anti – penetration, anti – erosion, anti – impact, anti – wear, good mechanical properties, strong structural integrity of furnace body, air tightness is better than brick furnace. The service life is prolonged, the cost of repairing furnace is saved, and the economic benefit is remarkable.

Advantages of low cement castable:

1. The low content of CaO in the castable can reduce the formation of low eutectic phase in the material. Thus the fire resistance, high temperature strength and slag erosion resistance are improved.

2. During construction, the mixing water consumption of low cement castable is only 1/3 to 1/2 of that of ordinary castable. Therefore, the porosity is low and the volume density is high.

3. After pouring molding, the cement compound generated in curing is less, and there is no large amount of hydration bond destruction during heating and baking, which leads to the decrease of the medium temperature strength. However, the strength gradually increases with the increase of heat treatment temperature.

4. The strength composition of the refractory castable can be properly adjusted to be composed of artesian castable and pumped castable.

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. The refractory castable generally has a higher strength at room temperature, can be made into prefabricated parts in the kiln construction site installation.
