THE ANALYSIS OF THE INTERFACIAL INSTABILITY CONDITIONS IN SYSTEMS<br /> LIQUID STEEL- REFINING SLAG
Journal Title: Journal of Science And Arts - Year 2008, Vol 9, Issue 2
Abstract
As consequences of the increasing needs of high quality steel products, besides the improvements of the actual technologies, applied in steel refining process using slugs a special attention is paid to new possibilities of quality improvement in liquid state in different stages of processing. A practical modality to apply actions to improve the quality, by preserving the beneficial contributions via limiting, avoiding or suppression of undesired effects, is to act at interface of the active involved phases steel and slag. Both beneficial and deleterious effects originate from turbulence and mixing developed at interface in adequate/inadequate moments and as intensities. Taking into consideration the complex interaction at interface, based on the solutal contributions, it is presented a comparative analysis of the threshold of instability in individual phases, according to one layer model, also of their interface. The conditions for turbulent convection by solutal Marangoni effect are also evaluated.
