Manufacturing Processes of Refractory Brick for Sale

Burnt Brick

In manufacturing process of refractory bricks, burnt bricks go through drying and sintering procedures. While after sintering, burnt bricks have a more rigid and stable structure and are less prone to deformation. Therefore, if you need high temp refractory bricks with strong mechanical strength, please choose burnt brick.

Unburnt Brick

Compared with burnt brick, unburnt brick is packed just after drying. Therefore, it has shorter production cycle. Besides, unburnt brick is lighter and easier to transport and install. In some projects that have high requirements for environmental protection and tight production cycles, unburnt brick is a better choice.

Fussed Cast Brick

Fussed cast refers to that manufacturers use electric to melt refractory bricks raw materials to obtain higher purity. Moreover, the fussed cast azs brick is one of the hot sale products of Kerui Refractory.
