Description
Magnesia-alumina carbon brick is a kind of non-fired products made primarily from magnesia, with the addition of high-alumina bauxite, corundum and flaky graphite. This product is developed by adjusting the process and technology based on alumina-magnesia-carbon bricks, enhancing the material’s corrosion resistance and spalling resistance. The product features high refractoriness, strong corrosion resistance, excellent thermal shock stability and good oxidation resistance.
