Product Description

Chinese Manufacturer Top Selling Low Porosity Fireclay Bricks for Lime Kiln Cement Kiln Furnace Lining:
Fire clay brick is a special type of brick made using fire clay and has a good resistance against high temperatures which are used
in kilns, lining furnaces, fireplaces and fireboxes. These bricks are manufactured in a way similar to that of normal bricks,
except during the burning process- Fire bricks are exposed to very high temperatures
The refractoriness of the brick is more than 1580ºC.

Also, we have SK36, SK37, SK38, SK40 refractory
high alumina bricks to choose. Their aluminum content is higher than fire clay bricks, and the use temperature is higher. If your
kiln needs higher temperature and longer service life, suggest you choose refractory high alumina bricks.
