Failure Analysis for Blast Furnace Using What If Analysis

R.Suresh, M. Rajesh Kumar, K. Tamil selvam

Blast furnace represents the dominate hot metal making production process worldwide and a largest unit in an integrated steel plants. The purpose of the blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called hot metal. Handling of blast furnace units is not a simple issue. During the blast furnace operation various hazards like fire and explosion, blast furnace gas which is more hazardous and explosive in nature are arise. Safety analysis requires a thoroughly methodological investigation such analysis must include the ability to deal with problems involving human error. In this paper what if analysis a systematic brain storming approach is applied to the two nodes of blast furnace units to find out the hazards and its consequences arise during blast furnace operation. Based on the results of what if analysis two nodes are prioritized and safety precautions, recommendations were suggested for the safe operation of blast furnace nodes.
