Ozone various methods for preparation

Slag-forming fluxes, chiefly burnt lime, fluorspar, and mill scale (iron oxides), are added in controlled amounts from an overhead storage system shortly before or after the oxygen jet is started. These materials, which produce a slag of the proper basicity and fluidity, are added through a chute built into the side of a water-cooled hood positioned over the mouth of the furnace. This hood collects the gases and the dense reddish brown fume emitted by the furnace during blowing, and conducts them to a cleaning system where the soflds are removed from the effluent gas before it is discharged to the atmosphere. Without access to sintering machines, which are largely closed by environmental constraints but used to be valuable faciUties to recycle dusts of various types, easy disposal is a problem (12).  [c.377]
