Modelling of slag emulsification and slag reduction in CAS-OB process
Autor: Sulasalmi, P. (Petri)
Composition Adjustment by Sealed argon bubbling – Oxygen Blowing (CAS-OB) process is a ladle treatment process that was developed for chemical heating and alloying of steel. The main stages of the process are heating, (possible) alloying and reduct

An improved model for the heat‐up stage of the CAS‐OB process:development and validation
Autor: Kärnä, A. (Aki), Järvinen, M. (Mika), Sulasalmi, P. (Petri), Visuri, V.-V. (Ville-Valtteri), Ollila, S. (Seppo), Fabritius, T. (Timo)
Details of chemical heating in the CAS‐OB process are not known exactly, making a computational model valuable in process development and control. A phenomena‐based numerical model of the CAS‐OB heating stage is presented. Chemical equilibrium

A CFD and experimental investigation of slag eye in gas stirred ladle
Autor: Ramasetti, E. K. (Eshwar Kumar), Visuri, V.-V. (Ville-Valtteri), Sulasalmi, P. (Petri), Fabritius, T. (Timo)
In ladle metallurgy, gas stirring and behavior of the slag layer are very important for the quality of the steel. When gas is injected through a nozzle located at the bottom of the ladle into the metal bath, the gas jet exiting the nozzle breaks up i

Numerical study of multiphase flows in a ladle for different closure models
Autor: Ramasetti, E. K. (Eshwar Kumar), Visuri, V.-V. (Ville-Valtteri), Sulasalmi, P. (Petri), Kärnä, A. (Aki), Fabritius, T. (Timo)
Computational Fluid Dynamics (CFD) modelling is increasingly being used for studying various metallurgical processes. In secondary steelmaking, gas stirring is used in ladles to enhance the mixing of the steel. This work aims at numerical study to in

A mathematical model for reactions during top-blowing in the AOD process:validation and results
Autor: Visuri, V.-V. (Ville-Valtteri), Järvinen, M. (Mika), Kärnä, A. (Aki), Sulasalmi, P. (Petri), Heikkinen, E.-P. (Eetu-Pekka), Kupari, P. (Pentti), Fabritius, T. (Timo)
In earlier work, a fundamental mathematical model was proposed for side-blowing operation in the argon oxygen decarburization (AOD) process. In the preceding part “Derivation of the Mode,” a new mathematical model was proposed for reactions durin

Modelling of open-eye formation and mixing phenomena in a gas-stirred ladle for different operating parameters
Autor: Ramasetti, E. K. (Eshwar Kumar)
In ladle metallurgy, gas stirring and the behaviour of the slag layer are very important for alloying and the homogenization of the steel. When gas is injected through a nozzle located at the bottom of the ladle into the metal bath, the gas jet exiti
