| titleOfInvention | A tundish working layer lining structure for adsorbing inclusions in molten steel |
| abstract | The invention belongs to the technical field of iron and steel metallurgy, and in particular relates to a tundish working layer lining structure for adsorbing inclusions in molten steel. The inner lining of the tundish working layer provided by the present invention contains a working lining layer of about 22-25 mm thick cast with MgO dry material, which acts as a refractory material, protects the tundish permanent layer, and prevents working The calcium-magnesium refractory on the lining surface has the effect of bonding with the permanent layer of the tundish. After the tundish is offline, it is easy to turn over the tundish, and the refractory on the working lining can be easily removed and re-laid. The inner lining of the tundish working layer provided by the invention contains a working lining surface layer rammed with calcium-magnesium refractory material of 70-80 wt% CaO. After reacting with the inclusions, a high melting point phase is formed, which can improve the anti-erosion performance of the working lining and prolong the service life of the working lining. |
