A method for preparation of the metal wire rod for plastic processingncomprising, carrying out cleaning treatment by at least one kind of cleaningntreatment method selected from the group consisting of shot blast, sandnblast, bending and acid cleaning of cathode and anode on the surface ofnmetal wire rod of 0.3-50 mm diameter for 20 seconds or less, contacting withnaqueous lubricious film formation treating solution which contains at leastnone kind of inorganic salt selected from the group consisting of phosphate,nsulfate, borate, silicate, molybdate or tungstate and at least one kind ofnslipping agent selected from the group consisting of metal soap, wax,npolytetrafluoroethylene, molybdenum disulfate and graphite, wherein, thenweight ratio of solid of said slipping agent/inorganic salt is within the limitnfrom 0.1 to 4.0 for 5 seconds or less, drying immediately and formingnlubricious film of adhesion amount from 0.5 to 20 g/m 2 on the surface of thenwire rod by continuous inline system. The method allows the preparation ofna metal material for plastic processing having excellent lubricatingncharacteristics in a short time. |
