Abstract
In-line flat-rolled steel cleansing and finishing apparatus is disclosed which enable flat-rolled steel, as supplied with surface areas contaminated with iron fines and other debris from gauge reduction operations, to be continuously processed in-line, free of interruptions for cleansing purposes. Continuous-strip apparatus is disclosed which enable in-line continuous-strip cleansing in a manner which decreases iron fines carried by strip surfaces to a desired level while providing for continuous uniform cleansing. Carry-over of iron fines from the cleansing operations so decreases such that iron content of a coating means is decreased resulting in improved corrosion-protection coating. Diminishing iron content in a hot-dip galvanizing bath increases efficiency of aluminum additions and diminishes iron-aluminum dross.
