It should be classified based on the production materials of refractory brick! In addition to ordinary light brick (cenosphere material), mullite poly light ball, there is lightweight high aluminum brick, lightweight clay brick, diatomite brick etc.!
Continuous casting use silicious insulation board, silica insulating refractory brick, ceramsite lightweight refractory concrete building block and so on. 0g/ clay lightweight heat insulating brick NGO.4-1.5g/, high aluminum lightweight heat insulating brickLGO.4-0.4-1.7G/, resistance furnace Diatomite brick 0; cm3; cm3; cm3, aluminum oxide insulating refractory products
0, perlite insulation brick.2 and so on; according to bulk density, the same lightweight refractory materials can be divided into 0, poly light high aluminum, lightweight brick. Light brick and alumina hollow ball brick.8, 1, 1 light refractory brick generally is classified according to the raw material composition and bulk density
