 G-High castables are aluminum based high temperature material. It is made from high alumina, bidding material as well as chemical ingredients. It shows features of high strength, excellent thermal shock resistance and corrosion resistance. It has a wide application in heating furnace, soaking pit, newly built power plant, electrolytic aluminum plant and cement, iron runner, working lining for ladle, and working lining for all kinds of furnaces, as well as ladle, tundish and all kinds of prefabricated parts. G-High castables have the features of stable volume, small coefficient of linear expansion, high strength, short baking time, and stable thermal shock resistance. We will produce castables according to the customers’ requirement.
