One of the key functions of the Porous Plug is to facilitate the removal of impurities and gases from the molten steel, resulting in a cleaner and higher-quality end product. By regulating the flow of gases, the Porous Plug helps prevent contamination and ensures that the steel meets industry standards for purity and composition. Hence, it is an essential component in the steel-making process, playing a critical role in maintaining the high quality of steel produced.
