Clay refractory bricks belong to one type of refractory bricks, and the precise definition belongs to the series of refractory materials. the perspective of material, clay refractory bricks are mainly made of refractory clay or corundum clinker, containing 30% to 46% alumina, with a refractoriness of 1580 to 1770 ℃, belonging to weak acidic refractory materials, with good thermal shock, and resistant to acidic slag, with a wide range of applications. Clay bricks made of refractory clay as the main raw material are called ordinary clay bricks, which classified into N-1, N-2, N-3 according to their grades. The ordinary clay bricks produced by Zhengzhou Huaang Refractory Material., Ltd. are first-grade clay bricks with more than 45% aluminum content.
Application scope: Clay bricks are used in secondary parts of blast furnaces, blast stoves, and coke ovens, as well as in other industrial furnaces, heating furnaces, calcination furnaces, and boilers, such as reg wall sealing, small flue lining bricks and regenerator grid bricks, furnace door lining bricks, furnace top and riser lining bricks, etc
