During blast furnace casting operations, the hot metal generates fume and particulate emissions. Environmental regulations require that blast furnace casting emissions by controlled. The casthouse of the No. 3 Blast Furnace at USS/KOBE in Lorain, Ohio was completely redesigned and rebuilt during the modernization of this facility. A state of the art casthouse emission control system was designed and installed as an integral part of the casthouse. Casthouse operations and maintenance, and environmental performance were foremost in the design considerations. This paper discusses the design, operations and results of this newly operational system along with some key design issues that were addressed with the EPA. The casthouse emission system as installed and permitted consists of the following: local evacuated hooding above the taphole to capture drilling, plugging and trough emissions near the taphole; a close fitting evacuated trough cover over that portion of the trough that is not covered by local hooding; an evacuated hood over the iron dam and skimmer; close fitting evacuated iron and slag runners covers on the entire length of the iron and slag runner system to capture iron and slag runner emissions; an evacuated enclosure covering the tilting iron spout to capture iron spout emissions; a baghouse operating at not less than 300,000 ACFM during casting operation to collect the captured emissions.
