Bulk density is an important physical and chemical index of refractory brick, which directly affects the compactness and thermal insulation and heat conduction performance of the brick. For the same size refractory brick, the greater the bulk density, the heavier the brick, which means that its density is better and the compressive strength is higher, and it can better resist the intrusion of external slag.
The relationship between the bulk density and weight of refractory brick is generally proportional and inversely proportional to the porosity. As the bulk density increases, the weight of the refractory brick will also increase accordingly, and the porosity will decrease accordingly. This means that for the same size refractory brick, the greater the bulk density, the heavier the weight, the more compact the internal structure, and the porosity will decrease accordingly. At the same time, the bulk density also directly affects the thermal insulation and heat conduction performance of the refractory brick.
