Abstract
PURPOSE:To perfectly remove oxide scale from the surface of an Ni or Ni alloy wire rod in a short time during production, by rapidly cooling the wire rod from a high temp. after hot rolling with grooved rolls and by carrying out pickling. CONSTITUTION:An ingot of pure Ni, an Ni-Cu alloy or an Ni-Cr-Al alloy for a wire rod is cogged or bloomed and the surface flaws, etc., of the resulting square bar are removed. The bar is heated in a heating furnace and repeatedly subjected to rolling with grooved rolls and process annealing to form a wire rod of a desired diameter. This wire rod is rapidly cooled from >=600 deg.C at >=50 deg.C/sec cooling rate to innumerably crack oxide scale on the surface of the wire rod and the oxide scale is dissolved and removed in a short time by pickling the wire rod. The pickled wire rod is bright-annealed and repeatedly subjected to cold drawing and bright annealing. Thus, an Ni or Ni alloy wire rod is produced with superior productivity.
