Product detail
Ladle
Fused magnesia and flake graphite are the main raw materials for these bricks, this series of products is produced by pressing and low temperature sintering. These bricks are mainly used for smelting low-carbon steel and ultra-low carbon steel in carbon-free ladles and slag line parts of low-carbon ladles.They have the characteristics of high strength, good corrosion resistance and excellent thermal shock resistance.
