Hot rolling of sections is the most productive technology of manufacturing long bars. Once the mill is set-up and ready for the production process, it can hot roll profiles in huge amounts with high productivity. In general, the temperature rises above 1.100 degrees Celsius. So the billets or blooms for the traditional "start-stop"-production method or wire rods for "endless" rolling method heat up to this level. Several roll stands
The raw material for cold rolling profiles is wire rod, which is a semi-finished product. The diameter of the rod depends also on the cross section of the final product. Similar to the endless hot rolling, cold rolling is also a continuous process, but at room temperature. The prodcution machinge leads the wire through different stands and so creates the desired shape with many passes. This process decreases the grain of the metal, the material becomes harder and the surface smoother and more shiny.
