US 5,669,957 A · Dross compression apparatus and method utilizing ribs on collector and head

Abstract

A dross compression apparatus and method utilizes a dross compression head and a skim box or collector having mating ribs. The ribs may be any type of projection or shape of the head and skim box sufficient to form grooves in both sides of the dross which divide or substantially divide the dross. Improved plating of the aluminum metal and separation of the aluminum layers from the aluminum oxide are achieved by using pressures in the range of 50 to 70 pounds per square inch. The ribs by their cutting action through the dross enable the achieving of these pressures with lower rated hydraulic presses. Two specific embodiments are disclosed, one utilizing an elongated substantially hemispheric shaped head and the other utilizing a substantially hemispheric shaped head. In both embodiments, the head and receptacle or skim box are of substantially conforming shapes.
