Brennerstein und Wärmespeicherbehälter

Considering the actual working condition of firebricks, our company produces them with the top quality corundum and mullite as the main raw materials, and adopts process of self-flow and vacuum pouring formation and firing by high temperature. The products are of behaviors of high strength, stripping resistance, corrosion resistance, scouring resistance, and good thermal shock resistance, and are applicable to heat accumulating tanks of various heat accumulating furnaces. And the specifications and models can be designed according to the requirements of users. Physical and Chemical Indexes of Firebrick.
