Installation of Purge Units for Supplying Inert Gases to the Molten Metal in Converters

Abstract

With combined metal blowing in an oxygen converter, the durability of the purge tuyeres when inert gases are supplied through the converter bottom is less than the durability of the converter lining because of the advanced wear of the tuyeres in relation to the bottom lining and the metallization of the capillaries/channels on the tuyeres with a slag–metal emulsion. To increase the performance of tuyeres, their placement in areas with the least wear of the lining and the avoidance of contact with the slag–metal emulsion are recommended.
