Introduction to Ladle Shroud
A ladle shroud, also known as a pouring tube, is a crucial refractory component used in the steel - making industry. It is installed between the ladle and the tundish during the continuous casting process. The main function of the ladle shroud is to prevent the molten steel from coming into contact with the atmosphere, thus reducing the oxidation and nitrogen absorption of the molten steel. This helps to improve the quality of the final steel product by minimizing impurities and ensuring a more uniform chemical composition. Additionally, the ladle shroud helps to control the flow of molten steel, ensuring a smooth and stable pouring process.
