Low cement refractory castable manufacturer

Low cement refractory castable is a high quality unshaped refractory which is often used in boiler lining. Most users are not familiar with the low cement refractory castable advantage. We are explain the application range of low cement refractory castables. You can see that as a reference.

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.

The above is about the characteristics and application of low cement refractory castable. If you have any questions, you can click on the inquiry, send us an email or ask customer service, we will be ready to answer for you. We can also customize the refractory materials you need, provide technical construction plan, welcome to consult and purchase.

Low cement castable usually refers to the refractory castable with little binder dose in preparation, whose thermal shock resistance, slag resistance and erosion resistance are significantly improved compared with other castable. If the binder dose is further reduced, it can be made into ultra-low cement castable and cement-free castable, which is a hot-selling product in the current market and has been well received and trusted by customers.

In low cement refractory castable, the admixture used is mainly high efficiency water-reducing agent and dispersing agent. Generally speaking, the water reduction and dispersion effect of organic admixtures is better than that of inorganic admixtures.

This series of refractory castable adopts the whole casting, which has the characteristics of low porosity, small size of porosity, high density, good volume stability, high strength and small amount of water. And overcome some of the shortcomings of ordinary castable，used the low cement refractory castable can double the thermal shock of furnace body.

The low cement refractory castable must be stirred by a forced mixer, using clean water at a suitable temperature of 10~25℃, and mixing with water in strict accordance with the mixing ratio given in the operating instructions.Welcome customers with purchase requirements to consult and purchase.
