Fireclay bricks are type of refractory material made primarily from natural clay. Aluminosilicate refractory materials with an Al2O3 content of 30%-48% are weakly acidic refractory products.It exhibits excellent refractory properties and thermal shock resistance, making it widely used in industries such as steel, glass, ceramics, and cement. ·Excellent refractory properties: With a refractoriness of over 1400°C, it is suitable for medium to low-temperature environments. ·Good thermal shock resistance: It can withstand rapid temperature changes, reducing damage caused by thermal shock.
Steel industry : used for lining and top of blast furnace and hot blast furnace.
Glass industry : used in the regenerator, flue and other parts of glass furnaces.
Ceramic industry : used for the walls, roofs and other parts of ceramic kilns.
Cement industry : used in preheaters, decomposition furnaces and other parts of cement rotary kilns.
Other industries: used for thermal equipment or building parts with fire resistance requirements.
