Low Porosity Dense Fire Clay Fire Brick

Low creep fire clay bricks are made of high-quality scorched gem refractory materials with less impurities and high purity as raw materials.The product is produced by high temperature sintering after batching, mixing, high pressure forming.Low creep fire clay has good stability,low creep rate,and good abrasion resistance.It is suitable for supporting large, medium and small blast furnaces, mainly used in the heat storage middle and lower walls, lower checker bricks, supporting strings and other parts.
