AN INNOVATIVE APPROACH TO AUTOMOTIVE PRELUBES(C)

Recent trends in the automotive industry have resulted in an increased need for technology which should provide corrosion protection and the required drawability in metal forming operations. A combination of ca lcium overbased sulfonate and petroleum oxidate can replace both mill oil and drawing compounds which are currently in use. The drawbead sim ulation test was carried out to investigate the effects of such lubric ants on drawing of electrogalvanized steel. The draw bead test demonst rated good performance when the above combination ws evaluated on galv anized steel test strips and performance was comparable to chlorinated paraffins at similar concentrations and viscosities in oil.
