What is the difference between ordinary refractory bricks and dense clay refractory bricks?

According to the different types of raw materials used in the production of refractory bricks, the bulk density of refractory bricks is also different. 

 

Generally, the refractory materials are measured for bulk density before leaving the factory. Bulk density: the ratio of the quality of the dried product to its total volume, expressed in g/cm3. The bulk density index is the main indicator for characterizing the compactness of the product. When the density is high, the intrusion of external slag and the like can be reduced.

 

Refractory bricks are divided into ordinary clay refractory bricks, dense clay refractory bricks, high-density clay refractory bricks, silica bricks, magnesia bricks, and aluminum-magnesium carbon bricks, which have different bulk densities, some of which are soft and some are hard. So, what is the difference between ordinary refractory bricks and dense clay refractory bricks? Sunrise refractory will tell you about the difference between the two.

Ordinary clay refractory bricks are generally 1.8 to 2.0 g/cm3, dense clay refractory bricks are generally 2.05 to 2.20 g/cm3, high-density clay refractory bricks are generally 2.25 to 2.30 g/cm3, and silica bricks are generally 1.80 to 1.95 g/cm3. Magnesia bricks generally range from 2.60 to 2.70 g/cm3, and aluminum-magnesium carbon bricks generally range from 2.90 to 3.00 g/cm3. The volume density index of the product is a comprehensive reflection of the pore volume and mineral composition in the product. It is usually used as a means of determining the degree of sintering of a product.
