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 ...

Production process
Rod diameters between 23.5 mm and 8 mm can be attained by constantly reducing the cross-section of the rolled material. The 400 to 500 °C wire is then surface-treated and cooled at a constant speed. The temperature is subsequently reduced to 40 °C. After it is dried and treated with a protective wax coating, the rod is wound into coils with a ...
