Selection of raw materials for magnesia carbon bricks
Graphite Graphite has a layered structure. The atoms in the layer are arranged together in a hexagonal arrangement with strong covalent bonds. There is a van der Waals force between the layers, which makes it have strong directionality, that is, obvious anisotropy. The inner layer and the entire surface contain low energy and hardly […]
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 […]
