What is the bulk density of high alumina bricks

 

Bulk density represents the ratio of the product's mass to its total volume, expressed in g / cm3. The bulk density index is the main indicator of the compactness of the product. When the density is higher, the intrusion of external slag and the like can be reduced. At the same time, the bulk density of high alumina refractory bricks is one of the important reference indicators for customers to adopt high alumina refractory bricks. The bulk density of high alumina refractory bricks for different uses is different. The higher the bulk density of high alumina bricks, the better the resistance to slag erosion.

 

High-alumina refractory bricks are divided into three-level high-alumina bricks, two-level high-alumina bricks, one-level high-alumina bricks and special-grade high-alumina bricks according to the content of alumina. . High alumina brick is divided into heavy high alumina brick and light high alumina brick according to the bulk density.

Factors affecting the bulk density of high-alumina refractory bricks

 

The volume density index of high alumina refractory bricks is a comprehensive reflection of the pore volume and mineral composition in high alumina bricks. Because it is relatively easy to measure, it is usually used as a method to judge the sintering degree of high alumina bricks. There are two factors that affect the bulk density of high alumina refractory bricks: one is the bulk density of the alumina content of the high alumina brick and the size of the alumina particle size; the other is the control of the production process. Therefore, when producing high-alumina refractory bricks, it is necessary to strictly select the grade of raw materials and control the particles, control the pressure of the brick press by the brick press during the production process, and reasonably control the firing of high-alumina refractory bricks.
