73. A Combined Physics-Based and Artificial Intelligence Through-Process Modelling of Steel Production Path

Božidar Šarler (University of Ljubljana and Institute of Metals and Technology)

14/10/2026, 16:10

Oral Presentation

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,...

83. A dynamic permeability model based on real-time local solidification time for macrosegregation modeling in alloy directional solidification

Haoran Xu (Institute of Metal Research, Chinese Academy of Sciences)

Oral Presentation

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...

41. Digital Twin–Based Simulation Chain for Rail Manufacturing: Roll Pass Design, Head Hardening, and Straightening

Nikolay Biba

14/10/2026, 16:50

Oral Presentation

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...

40. ESR simulation: prediction of quality and grain size for nickel based ingot

Cristian Viscardi (ECOTRE Valente srl)

14/10/2026, 17:10

Oral Presentation

ESR (electroslag remelting) process is fundamental in heavy forgings manufacturing, especially for energy and aerospace application. The aim of this paper is to analyze the quality and grain size of a nickel based remelted ingot using casting simulation software ProCAST. Melt pool profile, temperature distribution and solidification structure will be used to analyze quality; focus will be...

9. Ingot uphill casting defect potential reasons and forecast by different approach and analysis.

Dr Ferruccio Pastorino

14/10/2026, 17:30

Oral Presentation

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...
