Based on the principle of solidification shrinkage compensation, a soft reduction amount calculation method was derived for bloom continuous casting process, and bearing steel GCr15 chosen as specific research to describe process in detail. A two-dimensional heat transfer model built predict bloom, material properties were by weighted averaging phase fractions. The predicted temperature shell thickness verified thermal infrared camera nail shooting results, respectively. typical high carbon...
A combined cellular automaton-finite difference (CA-FD) model has been developed to simulate solute diffusion controlled solidification in continuous steel casting. Constitutional and curvature undercooling were both solved determine the equilibrium temperature growth velocity of solid/liquid interface. Simulations firstly performed for free dendritic from an undercooled melt columnar unidirectional solidification. Finally, competitive equiaxed transition (CET) occurring casting process...
A two-dimensional heat transfer model was developed to analyze the uneven solidification, particularly shape of solidification end in wide-thick slab continuous casting process. In order ensure accuracy simulation, material properties peritectic steel were calculated by weighted averaging phase fractions, and boundary conditions obtained realistic water flux distribution on transverse surface. The verified nail shooting results at different locations strand, absolute value relative error...
Electromagnetic stirring in mold (M-EMS) has been widely used continuous casting process to improve the solidification quality of steel strand. In present study, a 3D multi-physical-field mathematical model was developed predict macro transport phenomena with M-EMS using ANSYS commercial software, and adopted investigate effect current intensity (0, 150, 200, 240 A) on heat, momentum, species transports billet size 160 mm × mm. The results show that when is on, horizontal swirling flow...
Present study was undertaken to investigate the characteristics of solidification structure and sulfide inclusions in rail steel U75V continuously cast bloom using various methods, including metallographic examination, traditional 2D optical microscopy, 3D electrolytic extraction, SEM detection with EDS analysis, thermodynamic calculation for MnS inclusion precipitation. Metallographic examination shows that area ratio chill zone, columnar mixed zone equiaxed are 5.3%, 43.1%, 21.5% 30.1%,...
Through laboratory experiments and thermodynamic calculation, the chemical composition morphology of inclusion grain size in cast melt are comprehensively characterized herein. The results show evolution Al 2 O 3 formed by deoxidation gear steel 20CrNiMo follows route → CeAlO Ce S + CeS, thus nucleation core complex Ce m nS sulfides changes from CeAlO to CeOS with increase addition. Moreover, treated addition decreases 491.4 164.0 μm, because both CeS form have potential be effective...

This paper focused on the relationship between precipitation of TiN and continuous casting process 20CrMnTi billet. A reliable cross scale simulation combining heat transfer, solute micro-segregation, was carried out. Results show that for a specific site, cooling rate in mushy state increases with solidification proceeding, especially later stage solidification. The closer to center billet, lower initial is. However, near billet is higher than intermediate site. path at 20, 40, 60 mm below...
Based on Eulerian–Eulerian method, a 3D/2D multiphase solidification model, which takes into consideration the heat transfer and fluid flow with grains nucleation crystal growth, is developed to predict macrostructure evolution macrosegregation in continuously cast round bloom. The results show that mold electromagnetic stirring (M‐EMS) can accelerate superheat dissipation promote grain nucleation, but horizontal swirl induced by M‐EMS has strong washing effect front leads subsurface...
