Abstract (en)
[origin: EP0551657A1] In a method for minimising the crop end losses of concrete ribbed bars during their edge treatment by controlled cooling at rolling temperature, cooling being carried out, after the emergence of the bar from a bar finishing block, in a cooling section having a plurality of cooling tubes in series between the finishing block and a downstream loop layer and the bar being introduced into the loop layer after edge treatment, a significant reduction in the crop end losses is achieved by virtue of the fact that the cooling for comparatively thin bar thickness of between 6 and 10 mm is shifted into an area of the cooling section nearest to the loop layer. <IMAGE>
