ABSTRACT:
This disclosure proposes an improved method of and apparatus for collecting the fumes of a furnace but in particular of a steelmaking furnace using the basic oxygen blowing process which furnace rotates about a trunnion arrangement. Especially this disclosure applies to an improved fume collecting method for an oxygen steelmaking furnace whose emissions take place during the charging of scrap, during the charging of molten iron, during blowing oxygen in the furnace, and during the sample and temperature taking. This fume collection is accomplished by providing a hood of multiple purpose design adapted to collect the emissions during any of the aforementioned portions of the steelmaking cycle, which can be retro-fitted to existing steelmaking facilities.
