Magnesia carbon brick
Product introduction
MgO-C bricks are designed according to different operation conditions and application areas of the EAF lining. The bricks are made of pure flake graphite and large fused crystal magnesia which has high purity and density. Added with special antioxidant and takes resins as binders and finally shaped under high pressure.
PN series of MgO-C bricks are mainly used in the working lining of the EAF. It contacts with the molten steel and the slag directly. It features high strength, superior thermal shock resistance and slag corrosion resistance, etc. Based on different smelting conditions and application areas, PRCO provide various brands to choose from.
They have been used worldwide such as Novorossiysk Steel Mills in Russia, UMC in Thailand, Essar in India and Beshay in Egypt. The performance and stable quality have earned PRCO a great reputation among the customers.
