20.500.12556/RUL-173277 A meshless multiscale and multiphysics slice model for continuous casting of steel A simple Lagrangian travelling slice model has been successfully used to predict the relations between the process parameters and the strand temperatures in the continuous casting of steel. The present paper aims to include a simple macrosegregation, grain structure and mechanical stress and deformation model on top of the thermal slice framework. The basis of all the mentioned models is the slice heat-conduction model that considers the complex heat extraction mechanisms in the mould, with the sprays, rolls, and through radiation. Its main advantage is the fast calculation time, which is suitable for the online control of the caster. The macroscopic thermal and species transfer models are based on the continuum mixture theory. The macrosegregation model is based on the lever rule microsegregation model. The thermal conductivity and species diffusivity of the liquid phase are artificially enhanced to consider the convection of the melt. The grain structure model is based on cellular automata and phase-field concepts. The calculated thermal field is used to estimate the thermal contraction of the solid shell, which, in combination with the metallostatic pressure, drives the elastic-viscoplastic solid-mechanics models. The solution procedure of all the models is based on the meshless radial basis function generated finite difference method on the macroscopic scale and the meshless point automata concept on the grain structure scale. Simulation results point out the areas susceptible to hot tearing. continuous casting of steel slice model temperature grain structure macrosegregation stress and strain kontinuirano ulivanje jekla model rezine temperatura zrnatost makroizcejanje napetosti in deformacije true false true Angleški jezik Slovenski jezik Članek v reviji 2025-09-15 12:26:22 2025-09-15 12:26:27 2026-04-17 04:53:09 0000-00-00 00:00:00 2025 0 0 16 str. no. 9 Vol. 15 2025 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 621 2075-4701 10.3390/met15091007 248938755 metals-15-01007-v2.pdf metals-15-01007-v2.pdf 1 C13A5DD0C1195D250BE336836F9DADFA 0925e04a1ad9fa6e8b2a4779f900c26657affb9c1e2473272344bc3ff16dae03 7601a50b-398c-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=232578 https://www.mdpi.com/2075-4701/15/9/1007 1 44a41740-921e-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=217522 Fakulteta za strojništvo 0 0 0
