Abstract [en]

To investigate the importance of the vaporisation in the BOF process the vaporisation from a steel bath was simulated together with the condensation of the resultant gas phase. An additional calculation was also made to simulate the condensation when the actual BOF dust composition was used. The course of condensation was investigated to determine the final products. The results from the calculation were compared with the results from hot gas sampling in the off gas system of a 100-t BOF. Four gas atmospheres were used to study the influence of the different oxygen potentials on the condensation reactions. Special emphasis was put on the condensation reactions of Zn. The results show the importance of the vaporisation in the hot spot from which especially the elements having low vapour pressure will be vaporised. The increased O potential will mostly influence the course of condensation but not very much the final products. The calculated condensation temperatures indicate a possible temperature span suitable for separation of Zn, alkali and chlorine gas from dust by gas treatment at high temperature in BOF. Dust is characterised by a complex mineralogical composition and especially the surface of the ejected metal and slag particles seem to be the nucleus for condensation and perhaps subsequent oxidation reactions
