Objective A simulation model of the vacuum circulation process (VCP) for decarburization of steel has been developed. This model covers the steel circulation, the decarburization reaction, vessel pressure with its effect on the equilibrium conditions, and oxygen pickup from the ladle slag. Comparisons of simulation results with measured values of a VCP plant demonstrate that the model describes the process with excellent accuracy. Within the new project the simulation model shall be extended to include further metallurgical operations (such as stirring, gas input, oxygen blowing, dehydrogenation and nitrogen control), and it shall be applied in order to improve design, operation, process observation and process control of VCP plants.
