Liquid Metal Hold-up in Packed Beds

Abstract

IN recent years there appears to have been a growing interest in the investigation of liquid metal and slag irrigation of packed beds, either at zero gas flow or countercurrent to flowing gases. The interest apparently stems from a desire for a better understanding of the related processes in an operational blast furnace. So far, all such investigations have been performed under laboratory conditions. Moreover, because of various experimental difficulties, laboratory systems used for hold-up or other related studies featured liquids different to those of actual systems. One apparent exception is the recent investigation of the flooding phenomenon by Shavrin et al.¹ using molten slags.
