Modelowanie lepkości żużla konwertorowego
Języki publikacji
Abstrakty
The paper is devoted to one of the most important factors influencing steel melting and operation of an oxygen converter, i.e. dynamic viscosity of slag. Knowing typical chemical composition of slag after melting, the viscosity was calculated with the use of Riboud and Urbain empirical models at temperatures 1400 °C to 1700 °C. The obtained mathematical results were compared with the results of simulations obtained with the FactSage program. The discrepancies between these results were caused by model assumptions and the fact that slag in lower temperatures consisted of liquid and solid phases.
Obecna praca poświęcona jest jednemu z najważniejszych czynników wpływających na pracę konwertora tlenowego - lepkości dynamicznej żużla. Znając typowy skład chemiczny żużla uzyskany po wytopie w piecu wykonano obliczenia lepkości żużla przy pomocy empirycznych modeli Ribouda i Urbaina w zakresie temperatur od 1400 °C do 1700 °C. Wykonano również analizę porównawczą wyników obliczeń przy pomocy modeli z wynikami symulacji uzyskanymi z kalkulacji wykonanych za pomocą programu FactSage.
