Abstract
BOF Post Combustion Oxygen Lances continue to be used as a production and maintenance tool to improve the steelmaking process. By optimizing the Post Combustion Ratio inside the BOF vessel, steelmakers can take full advantage of the increase in chemical energy, which can result in faster blow times, higher scrap-to-hot metal ratios, and reduced skulling on the lance barrel and reduced build-up on the furnace mouth. New developments with post combustion will be described, along with the operational results and benefits.
