Objective Large H-sections are usually straightened in presses. Compared to conventional roller straightening, this process presents disadvantages in terms of throughput and economy. However, conventional roller straightening may produce relatively high residual internal stresses between the flange and web, possibly diminishing quality. By roller straightening via application of the straightening force through the flange tips, it is possible to straighten such sections more economically and with better quality (avoidance of residual internal stress peaks), as was successfully demonstrated in the ECSC project 7215.EA/803. The objective of the proposed pilot project is the further development of this progressive straightening technique in mills producing H-sections of different dimensions. To verify the improved product quality, residual stress measurements will be carried out to allow comparisons between beams straightened conventionally and by the new technique.
