PRODUCT DESCRIPTION

Semi-Rebounded and Rebounded Magnesia-Chrome bricks are made partially or fully with synthetic electro-fused clinkers. They are shaped under high pressure and sintered at very high temperature. They have high strength and good volume stability and applied widely in refining furnaces such as RH, VOD and AOD as well as non-ferrous furnaces.
