...Ambrish Maurya; Pradeep Kumar Jha Purpose This investigation aims to analyze the steel-flux interface level fluctuation because of electromagnetic stirring and its process parameters in a continuous casting billet mold. Design/methodology/approach An un-coupled numerical model...

...Chennu Ranganayakulu; Jaideep S. Mathur; Perumal Nithiarasu; R.S. Sudheesh; N. Siva Prasad Purpose The purpose of this paper is to study the effect of trailing liquid nitrogen (LN2) heat sink on arc welding of mild steel plates. The effect on temperature field, stress and distortions are studied...

... equations are solved numerically using a control volume approach for the case of a gas assisted laser heating of steel surfaces. Various turbulence models including standard k‐ε, k‐ε YAP, low Reynolds number k‐ε and RSTM models are tested. The low...

...Jürgen Fuhrmann; Dietmar Hömberg We discuss a model that is capable of describing the solid‐solid phase transitions in steel. It consists of a system of ordinary differential equations for the volume fractions of the occuring phases coupled with a nonlinear energy balance equation to take care...

...M. M’Hamdi; H. Combeau; G. Lesoult The general aim of this work is to calculate the extent of the equiaxed zone in continuously cast steel products. Free equiaxed grains can grow only in undercooled liquid regions. Undercooling of the bulk liquid occurs because the columnar dendrite tips growing...
