Control of the yielding and aging behaviour in temper rolling

Ziel

The development of ULC and BH steel grades and the adoption of short annealing lines with high speed cooling and short overaging sections, produces sheet with higher levels of carbon in solid solution. Accurate setting of the temper rolling conditions is required to suppress the yield point elongation while keeping final yield stress as low as possible to increase the deep-drawing properties. The aim of this research project is to improve knowledge of the internal stresses along the strip prior to skin-pass rolling and to develop a model, which allows the internal strain to be estimated from the sheet thickness after temper rolling. It will allow final yield stresses and optimal rolling conditions to be determined, as well as the effects of temper rolling on the subsequent ageing phenomena.
