A three-phase mixed columnar-equiaxed solidification model is used to calculate the macrosegregation in a 2.45 ton steel ingot. The main features of such an ingot can be quantitatively modelled: growth columnar dendrite trunks; nucleation, and sedimentation equiaxed crystals; thermosolutal convection melt; solute transport by both crystal sedimentation; columnar-to-equiaxed transition (CET). predicted as-cast macrostructure segregation pattern are qualitative agreement with reported...
The Electroslag Remelting (ESR) is an advanced technology for the production of high quality materials, example, hot work tool steels or nickel base alloys. In past years, several models are developed aiming to predict way in which operational parameters affect structure and chemical composition final ESR ingot. Proper modeling this process depends on ability model Multiphysics resulting from complex coupling between many physical phenomena. This review includes main findings starting...
Mold electromagnetic stirring (M-EMS) has been introduced into the continuous casting of steel billets to promote formation a central equiaxed zone; however, mechanism crystals and effect M-EMS on crystal transport are not fully understood. Currently, three-phase volume average model was used study solidification in billet (195 mm × 195 mm). The modeling results showed that main function this type is superheat dissipation mold region, leaving liquid core out region undercooled. Although...
Avoiding particle entrapment into the solidifying shell of a steel continuous caster is important to improve quality cast product. Therefore, fluid flow dynamics in melt and mushy zone, heat transfer solidification shell, as well motion inclusion particles during casting process were investigated using computational models. Solidification strand modelled with an enthalpy-formulation by assuming columnar morphology zone. The tracked Lagrangian approach. When reach front, they can be...
Abstract Centreline macrosegregation is often observed in continuous slab casting of steel. Two the main formation mechanisms are bulging and feeding. Both were studied compared current work by using a two‐phase volume averaging model considering only columnar solidification. The strand itself modelled applying predefined velocity following speed solid shell deformation (e.g. bulging). Three different cases simulated discussed. (i) first case considers influence feeding flow during...
