Abstract

A thermodynamic and kinetic model of the converter steelmaking process was developed allowing the analysis of the influence of the technological parameters, such as the amount and addition time of a charge material on the chemical composition of the crude steel. The process of the manganese ore addition to the converter to increase the final content of manganese in the crude steel was simulated. The optimal technological parameters for the enhancement of manganese yield were determined.

Zusammenfassung

Ein thermodynamisches und kinetisches Modell wurde zur Simulation des Sauerstoffblaskonverter Verfahrens entwickelt, womit der Einfluss der technologischen Parameter, wie die Menge und der Zeitpunkt zur Beschickung der Zuschlagsstoffe, auf die Zusammensetzung des Rohstahls untersucht werden kann. Das Verfahren des Einsatzes von Manganerz in den Sauerstoffblaskonverter, um den Endgehalt vom Mangan im Rohstahl zu erhöhen, wurde simuliert. Die optimalen technologischen Parameter zur Steigerung der Manganausbeute wurden bestimmt.
