Hot Bottom Repairs: Global Impact, Performance Case Study And Development For The Americas

Hot Bottom Repair (HBR) was first introduced by Fosbel, around 2000 and has been successfully implemented at a global level to-date. Since then, improvements have been made to the repair processes that have resulted in an observed increase on the average repair life. An actual in-situ furnace post mortem analysis highlighting the material's performance in different areas of the furnace is shown in this article. In addition to presenting process application improvements, the current state of development of the next generation HBR material, with a joint effort with N American Refractories Company is discussed.
