Clay bricks are widely used in metallurgy, blast furnaces and hot blast furnaces, chemical industries waste incinerators, glass melting furnaces. It is the first selection of thermal equipment permanent lining material. Fire clay brick is mainly used in the low temperature parts of various industrial furnaces, due to the scale-up of a variety of industrial furnaces and severity of operating conditions, super dense clay bricks that made of more refined chamotte being calcinated at high temperature are applied more than before. Clay fire bricks are made of calcined clay and binder. They are a type of siliceous alumina brick. Their refractoriness is between 1580-1770 degrees Celsius. With the change of composition, the refractoriness fluctuates. In addition, because clay bricks contain alumina, they have a certain anti-erosion effect on acidic slags. They are generally used in acidic slag kilns.
