Deoxidization is a method used in metallurgy to remove the oxygen content during steel manufacturing. In contrast, antioxidants are used for stabilization, such as in the storage of food. Deoxidation is important in the steelmaking process as oxygen is often detrimental to the quality of steel produced. Deoxidization is mainly achieved by adding a separate chemical species to neutralize the effects of oxygen or by directly removing the oxygen.

Answer this question: how entrapped bubbles of gases are removed from steel? Let's give stream of consciousness first:
To answer the above question, the relevant sentence is: Deoxidization is mainly achieved by adding a separate chemical species to neutralize the effects of oxygen or by directly removing the oxygen.
So, the final answer is adding a separate chemical species to neutralize the effects of oxygen or by directly removing the oxygen.
