Any formation of a sticky semi-fused slag in the narrow bosh incline is likely to cause difficult to gas flow and material descent.which causes bosh hanging. This irregularity can be rectified by shifting slag fusion zone from bosh to belly by injecting of suitable coolants along with the blast at the same raised blast temperature.
*the more danger of bosh hanging lies in the case of lean ores because of high reducibility and low FeO contents.
