Molten steel is prone to oxidation more than molten iron, making deoxidation a necessary step. Conventional methods typically use aluminum, a strong deoxidizer, but it has drawbacks such as low density and floating on slag. Cored wire technology offers an economical alternative by employing deoxidizers like calcium silicate and ferrosilicon.
