摘要： PROBLEM TO BE SOLVED: To provide a method of forging a steel wire rod without needing a new additional heating means and also deteriorating the dimensional accuracy of a rod shape after final forging, by which the adjusting time during high-temperature straightening can be shortened in a process for producing a forging product from a coiled steel wire rod using single production line. SOLUTION: The method is characterized by including: a step of getting through a cold-straightened steel wire rod 1b as it is without straightening by a three-point bending machine 3 for straightening and charging the top 1c of the wire rod in an upstream-side induction heating furnace 4a to heat to a prescribed temperature T; and a step of returning once the top of the wire rod 1d bent by heating to the prescribed temperature to the upstream side to straighten the rod almost linearly by the three-point bending machine 3 for straightening.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing, by using a round steel rod material, a flat wire for a ring gear which satisfies the requirements of both surface hardness and dimensional accuracy thereof and has reduced hardness variation without requiring a heat treatment for absorbing the hardness elevation of a flat wire surface.
SOLUTION: When producing the flat wire for the ring gear by a cold working process using the round steel rod material having a carbon content of 0.30-0.60%, at least one two-way or four-way rolling reduction is performed after at least one cold rolling or cold roller drawing process. In the final step of such cold working process, drawing is performed by using a drawing die to process the whole peripheral surface of the flat wire so as to achieve the maximum area reduction rate of a total sectional area of ≤65%. Thereby, excellent dimensional accuracy and reduced variation in both width and thickness directions are achieved, and thus a required hardness can be obtained while suppressing the occurrence of crack at the side face of the flat wire without requiring intermediate heat treatment.

摘要： PURPOSE:To control the composition and thickness of scale on the surface of a hot rolled wire rod by rapidly cooling the wire rod and finishing pearlitic transformation in a regulated atmosphere. CONSTITUTION:A hot rolled wire rod is rapidly cooled to a prescribed pearlitic transformation start temp. of about 600-700 deg.C to reduce the thickness of scale on the surface. The scale is then held in an atmosphere contg. about 50% CO for forming only an FeO phase at about 600-700 deg.C until pearlitic transformation is finished, and the wire rod is rapidly cooled at once to prevent a change in the composition of the scale. Thus, a wire rod having an internal structure having superior cold workability is obtd.
