High Quality Fire Clay Brick Supply

Clay bricks are also known as sintered bricks. Clay brick with clay as the main raw material, after clay material processing, molding, drying and roasting, there are solid and hollow respectively.

Clay bricks are generally used in the brickwork of heating and heat treatment furnaces, flue, open hearth regenerator lattice tiles, as well as the bottom of the regenerator wall, lining of air and gas pipes. The lining of the dust collector and flue in the iron furnace, the drying of the rotary kiln and the pre-heating zone are also constructed with clay bricks.

From the appearance, clay brick is generally composed of a small number of black spots, and the distribution is more uniform. Generally speaking, black spots represent the impurities of iron oxide, the more black spots, the more impurities, the fire resistance is not high enough. Also can touch clay brick surface is smooth, without crack, do not prick. Clay firebrick of average quality can have very big crack, very troublesome hand, such clay firebrick, compressive strength is low, the erosion that suffers harmful gas very easily, accordingly, this kind of firebrick cannot be used in building main place.

From the body structure, the quality of good clay brick body structure is clear, angular, there is no lack of Angle or lack of edge. The clay fire brick with no edge will greatly weaken the strength of the wall and affect the quality of the whole project.
