Tag: refractory material

The key factors affecting the life of the refractory material of ladle slag line bricks

The ladle slag line is the part where the molten steel is in direct contact with the air. At present, magnesia-carbon bricks are mostly used in the masonry of the ladle slag line. Due to the existence of temperature difference and oxygen-enriched environment, the erosion rate of this part is significantly faster than that of […]
