Low Porosity Fireclay Refractory Products High Alumina Brick
The Description:
Low porosity clay brick and dense clay brick is the same product, in fact, low porosity brick is also called dense clay brick, mainly in the production of focusing on the porosity and production, control the size of the porosity, is to add different proportions of coke gems to adjust the porosity of clay brick, and thus to increase the density of clay brick, so that its density is good, better compressive strength.
The general clay brick and low-porosity brick press process, the sintering temperature is basically the same, but the process ratio has changed, the low-porosity brick process adds a certain ratio of burnt gems, and the ordinary clay brick is not added to the burnt gems and produced. The clay brick after adding coke gem is a low-porosity brick, also known as dense clay brick, because of its low porosity, good strength and stronger erosion resistance. The amount of kiln lining used in the glass industry is relatively large.
