ICRF 2026 - 5th International Conference on INGOT CASTING, ROLLING & FORGING

A part of the digitalisation efforts in the steel industry concerns the numerical optimisation of the steel production chain to increase quality, productivity, and sustainable production. We present the multiscale computational modelling of a typical steel processing route, comprising continuous casting, controlled cooling, annealing, reheating, reverse and continuous hot rolling, cooling bed,...

The work introduces a unified virtual process chain for rail production that combines roll pass design, hot rolling, differential quenching of the rail head, and final straightening within a single simulation route. The first stage is carried out in QKaliber, where analytical models are used to evaluate pass geometry together with the main process variables, including deformation, thermal...

A dynamic permeability model based on real-time local solidification time (LST) is proposed to improve macrosegregation prediction in alloy directional solidification. By tracking the solidification history of each computational cell with a state-machine algorithm, the model dynamically updates the secondary dendrite arm spacing (SDAS) using an experimental LST–SDAS relationship and evaluates...

Uphill casting is widely used to cast high quality ingots in order to reduce several defects coming from gas or solid trapped inclusions, inhomogeneity, holes consequent to the direct pour casting etc. Uphill casting reduce turbulence, improve slag removal by floating slag particles on the ingot top. Notwithstanding that, there are several reasons that can generate troubles in the final...
