Objective
The techniques for thermo-mechanical treatment during rolling were developed many years ago to improve the mechanical properties of plate, wide strip and reinforcing rod. Weldability is also better. Since 1982, the process has been extended to high-weldability merchant steel produced by the KLÖCNER-MANNSTAEDT. The maximum thickness of the products dealt with is 10mmm The technology which will have to be developped in the first place will concern colliery arches: regulation of the final cooling of these sections is aimed at refining the ferritic structure of grades with up to 0.3%C. It is also wished to improve the strength properties of these sections Cooling will be controlled by means of water jets by proper adjustment of the flow of water and the direction of the jets. This process should avoid any further heat treatment. The tests will be carried out on the rolling mill at Valenciennes.
