Introduction
Magnesia carbon bricks for converter The magnesia carbon brick series are made of high purity, high density, large crystal fused magnesia and natural graphite with antioxidant and phenolic resin. They are iso-pressed pieces under high pressure with high strength, high refractoriness, strong resistance to slag and thermal shock. JHCO can provide various MgO-C bricks for different areas of BOF lining where directly contact with the molten steel and slag.
