Magnesia-carbon bricks should control the graphite content in the bricks to be about 20%. Magnesia-carbon bricks have low wettability to slag, and have excellent resistance to spalling and erosion. They are suitable for the slag line of the ladle, especially in the case of multi-furnace continuous casting. In order to meet the needs of producing clean steel, the application part of magnesia-carbon bricks has been expanded from the slag line to the side wall during refining in the ladle.
When laying magnesia-carbon bricks on the ladle, care should be taken not to mix with bricks containing high SiO2. Otherwise, the local melting loss of magnesia-carbon bricks will be increased. Steel drum slag line parts, etc.
