To produce clean and fully killed steel, the refining process involves treating the steel with aluminum (Al) or silicon (Si) or a combination of both.
By adding the last part of the Si addition to a fully killed steel in the ladle, the recovery was much higher.
Adding aluminum-coated or aluminum killed steel can provide an iron oxide reactant that will help to preserve the refractory lining.
For example, aluminum-coated or killed steel used in cast iron melting will result in alumina or alumina complex mineral deposits such as hercynite (iron aluminate), mullite (silica alumina), etc.
