Clay bricks, using high alumina bauxite as raw refractory material which is being carefullly selected and then be shaped and burn in tunnel kiln, finnaly made the clay brick. Clay bricks is very cheap, it is the best choice for normal high temperature kiln. Clay bricks is one kind of weak acid refractory products, it can resist erosion from acid slag and acid gas.
Clay brick's thermal performance is good, it also has good resistance to rapid cooling and hot. Clay refractory bricks are widely used in blast furnace hot stove, carbon roaster and other high temperature furnace which have an higher requires in Load softening temperature.
