The slag ladle is a container that can store and transport molten steel during the smelting process. Nowadays, due to the rapid development of the manufacturing industry, the manufacture of some important equipment and instruments requires the continuous improvement of the quality of steel, so the purity of steel must be improved. Removing inclusions from molten steel and strictly controlling the composition of some harmful elements in molten steel, so refining in the slag ladle has become a way to improve the quality of steel. Slag ladles have since changed from a simple molten steel container to a multi-element container with smelting functions.
The lining of slag ladles mainly consists of three parts:
- The first part is the working layer. The working layer is directly in contact with molten steel and slag during ladle smelting, and is eroded by molten steel and slag, and is susceptible to large temperature differences. Therefore, the refractory materials used in the working layer are often severely damaged and need to be regularly inspected and replaced;
- The second part is the permanent layer, which is about 30-60mm thick. The permanent layer plays the role of the main skeleton of the slag ladles, and plays a vital role in preventing molten steel leakage and maintaining the safe operation of the ladle. Therefore, the life of the ladle is related to the quality of this layer. This layer is generally built with clay and high-alumina bricks, usually in a comprehensive way.
- The third is the insulation layer, which is close to the steel plate and has a thickness of about 11-15mm. The main function of the insulation layer is to insulate the molten steel, reduce the heat loss of the molten steel, and reduce the energy consumption of steelmaking. The opening of the sliding water gate of the slag ladles is used to control the size of the molten steel flow and the height of the liquid level of the tundish.
