PURPOSE:To prevent a wire rod from corrosion in a short stage and to reduce the cost of corrosion resistant wire rods by blasting iron and zinc particles on the surface of a mechanically descaled continuous wire rod to form a porous alloy layer, infiltrating a lubricant, and cold drawing the wire rod. CONSTITUTION:Iron and zinc particles are blasted onto the mechanically descaled surface of a continuously transferred wire rod to form a porous iron-zinc alloy layer. Mineral, animal, and vegetable oils, etc., are sprayed onto the layer to form an infiltrated lubrication film and the wire rod is cold drawn. A uniformly and strongly sticked corrosion resistant layer is formed on the wire rod surface. This method remarkably shortens the stage and reduces the manufacturing cost compared with a conventional method in which a wire rod is mechanically descaled, is subjected to a reaction saponification treatment by use of sodium stearate, etc., after a surface preparation by use of zinc phosphate, etc., is quickly dried, and is drawn. Forming a fluororesin film on the blasted surface and infiltrating a lubricant are also useful.
