Rods. Rod mills are similar to bar mills at the front end, but the finishing end is different. Rods have a smaller section (5.5 to 15 millimetres in diameter) and are always coiled, while bars are normally shipped in cut length. The final rolling in rod mills often takes place in a close-coupled set of 10 pairs of small rolls (200 and 150 ...

Primary vs Secondary Steelmaking: What's the Difference…
The defining characteristic of secondary steelmaking, however, is its use of an electric arc. 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.
