Description
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. It is mainly used for carbon furnace, baking furnace, heating boiler, glass furnace, cement kiln, fertilizer gasification furnace, blast furnace, the hot blast stove, coking furnace, furnace, casting and casting steel brick, etc.
Also, we have 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.
Characters:
1.Good resistance to corrosion and abrasion.
2.Perfect thermal shock resistance.
3.Good spalling resistance.
4.High mechanical strength.
5.Good volume stability under high temperature.
