Abstract

The service life of blast furnace (BF) hearth can be threatened mostly by air gap. The present paper is set on the investigation of hearth problem and makes analysis on reasons and factors of generating air gap through theoretical calculations and field survey. Effective measures are proposed herein for preventing air gap by well managing every link concerned. It’s taken a package solution to realize zero-gap hearth operation and long campaign furnace.
