Industrial Investigations of the Liquid Steel Filtration

K. Janiszewski, B. Panic: Silesian University of Technology, Department of Metallurgy, Katowice, Poland Hitherto existing investigations concerning the ceramic fi lter use in the steel making processes have given good results. The obtained results of fi ltration have proved that this method may be used as an eff ective and cheap way of steel fi ltration from non-metallic inclusions. Placing fi lters in the tundish is the best location considering the limitation of the possibility of secondary pollution of steel. Yet, the results presented in this paper, of an experiment prepared and carried out in the industrial environment, are the only positive results obtained, which are connected with so much quantities of liquid steel processed with use of the multi-hole ceramic fi lters.
