Primary vs Secondary Steelmaking: What's the Difference ...

2019-10-11 · Primary steelmaking uses a blower to force oxygen through molten iron, whereas secondary steelmaking is characterized by the use of an electric arc. The electric arc is able to heat up the scrap iron until it achieves a molten state. Furthermore, it’s important to note that primary steelmaking doesn’t dissolve the oxygen.
