Abstract
A method of rolling steel sections, particularly in a universal section mill, wherein X-shape rolling and H-shape rolling are carried out alternatingly and specifically directed cooling of the steel section is carried out during rolling. During roughing rolling in a X-shaped groove a cooling water channel is formed at each side of the steel section at the connecting locations between web and flange. The roll cooling water flowing off from the H-shaped rolls is concentrated in the cooling water channels. An additional quantity of water may be added either without pressure or in the form of spray water to the concentrated roll cooling water.
