The Refractory Ladle Purging Plug is inserted into the ladle bottom or side wall and serves as a gas injection point. It allows the injection of an inert gas, such as argon or nitrogen, into the molten metal to remove impurities and enhance the steel's cleanliness. The purging plug is made from high-purity alumina ceramic, which offers excellent thermal resistance and chemical inertness in high-temperature ladle environments.
