SUMMARY:Evaluation of Hearth Condition over Whyalla No. 2 Blast Furnace Campaign
DESCRIPTION:Liberty Primary Steel’s Whyalla No. 2 Blast Furnace (W2BF) has operated for over 17 years since blow-in in 2004. The measured refractory temperature trends in the hearth show unique variations at different stages during this campaign, influenced by a variety of different refractory and operational conditions. From an operational perspective, an investigation was begun to more deeply understand the hearth and refractory condition throughout the whole W2BF current campaign. This included detailed investigations of the refractory, coke bed status and corresponding liquid flow behaviour in the hearth. In this study, a methodology was proposed to help explain the refractory temperature measurements (trend) based on simplified and comprehensive fluid flow and heat transfer modelling, measured refractory temperatures and other relevant operational data. Results of this comprehensive study show that the estimations of hearth refractory and hearth conditions determined from different sources are consistent over the course of the campaign. The predictions are verified through comparison between calculated and measured data, over the whole campaign life.
