How to calculate the volume density of refractory brick?
According to different types of refractory raw materials, their density is also different. Generally, the bulk density of refractory materials is measured before leaving the factory. Bulk density: refers to the ratio of the mass of the dried product to its total volume, in g / cm3. The bulk density index is the main index to characterize the density of the product. When the density is high, the invasion of external slag can be reduced.
Ordinary clay brick is 1.8 ~ 2.0 g / cm3
Dense clay brick is generally 2.05 ~ 2.20 g / cm3
High density clay brick is 2.25 ~ 2.30 g / cm3
Silica brick is generally 1.80 ~ 1.95 g / cm3
Magnesia bricks are generally 2.60 – 2.70 g / cm3
Alumina magnesia carbon brick is generally 2.90 ~ 3.00 g / cm3
The bulk density index of products is a comprehensive reflection of pore volume and mineral composition in products. Because it is easy to measure, it is usually used as a method to judge the sintering degree of products in production
