There are severe uneven “cat ear” wear contours of work rolls, the key factors to affect high‐quality profile and flatness control of electrical steel strips, in the schedule‐free rolling (SFR) process with a large number of the same width strip rolling campaigns of hot rolling mills. The work roll wear prediction model, thermal roll contour model and a 3D finite element model of roll stacks and strip

During Electric Arc Furnace (EAF) steelmaking process, burnt lime is charged together with other slag forming materials to attain a specific basicity of the slag and to achieve purification by removing unwanted elements. In this study, fly ash containing ∽60% CaO generated from pulp/paper mills was tested to partially (15‐50%) replace primary lime in pilot scale EAF trials. The obtained results showed

Multiphase CFD simulations of steel recirculation flow in a RH process are realized by a Discrete Phase Model (DPM) for the driving bubble plumes, a Volume of Fluid (VoF) method for the free surface in the Vacuum Chamber (VC) and a Large Eddy Simulations (LES) model for the transport and mixing of steel alloys. CFD simulations are opposed to Particle Image Velocimetry (PIV) analyses of flow pattern

The European steel industry aims at a CO2‐reduction of 80‐95 % by 2050, ensuring that Europe will meet the requirements of the Paris Agreement. As the reduction potentials of the current steelmaking routes are low, the transfer towards breakthrough‐technologies is essential to reach these goals. Hydrogen‐based steelmaking is one approach to realize CO2‐lean steelmaking. Therefore, the natural gas‐based

Tools play a decisive role in the manufacturing chain, as they substantially influence key factors such as cost, lead time, as well as product design, quality, and performance. Improvements in tooling, therefore, have the potential to strengthen the competitiveness of virtually any manufacturing company. The 11th International Tooling Conference took place in the historic city of Aachen, Germany from

A new one‐step process for manufacturing Press Hardened Steel‐Carbon Fibre Reinforced (thermoset) Polymer hybrid parts with potential for reduced cycle‐time, infrastructure requirements and energy consumption compared to traditional two‐ and three‐step processes is developed. The process combines and optimises the press hardening and Prepreg Compression Moulding technologies, traditionally used in
