A study is undertaken of the lubrication of steel wire drawing using a Christopherson tube and a polymer melt as a lubricant. Primary objectives of the study are to determine the criteria under which a thin, well adhered coat of the polymer is deposited on the wire after drawing. An analysis determines these criteria and enables the polymer coat thickness to be obtained for given operating conditions. Several flow defects are observed and discussed.
