Long Product Quality Optimisation through Enhancement and Utilisation of Residual Stress minimising Process Strategies

Seminar with TEAMS meeting

Oct 30th, 2024 – Oct 30th, 2024seminar in english

During rolling, straightening and thermal processing of long products internal stresses arise impairing the products materi-al properties and causing material distortion due to stress relief mechanisms. The characteristics of those effects are still associated with a high degree of uncertainty. The seminar gives an overview of the research work done and the resultant proposed solutions that can be implemented with limited ef-forts in terms of residual stress minimising process strategies to increase the economic efficiency and the future perspective to achieve better product quality in hot rolling of long products.

Process water treatment and concentrate handling in steel plants

Onsite workshop on industrial water management in Düsseldorf

Dec 12th, 2024 – Dec 12th, 2024seminar in english

Water is a mandatory medium in iron and steel production for cool-ing applications, material treatment and gas washing processes. Due to climate change, water stress increases and limits the avail-ability of water and change the water composition. This requires innovative approaches, to open up new water sources as blow down and cooling water in combination with an optimisation of the water management by simulations and forecast tools.
The workshop gives an overview on the latest developments for Process water and concentrate handling by opening new water sources as waste waters in iron and steel industry. Innovative re-search institutes, plant manufactures and companies from metal and steel production industry will give an insight into their latest approaches.
