1、 Magnesia carbon bricks are unburned refractory which have been made by high power pressing and drying at a high temperature. It is resin-bonded and made with fused-grain magnesia, high purity magnesia and high purity flake graphite. They have excellent corrosion, thermal shock resistance and spalling resistance. They wide applications and can be used in key locations of thermal processing equipment such as BOF, EAF, LF and so on.
2、 Alumina-magnesia-carbon brick made from high-purity bauxite or fused alumina and fused magnesia grain or high purity magnesia by pressing, Resin-bond for thermal shock resistance. Additions of metallic antioxidants to minimize oxidation. Additions of carbon for improved slag resistance. Spinel formation improves hot strength, slag resistance and brick joint erosion.
3、 Repairing material for BOF uses fused magnesia or sintered magnesia as the main raw material and after modifid pitch and special additives are added, it has the following characteristcs than other conventional converter pitch temperature, shorter sintering time, longer service life and less pollution .It is mainly used for repairing converter working face, also for tapping side, tapping hole and bottom.
4、castables for blast furnace trough has strong resistance to erosion of hotnetal and slag with good thermal shock resistance and low reheating linear change rate, strong anti-oxidation ability, Easy for construction and sticky to slag and convenient for repairing and disinantling. No harmful gas formed and beneficial to environmental protection.
