摘要： PROBLEM TO BE SOLVED: To provide a forged product which is high in fatigue strength in both end parts of the forged product, furthermore, small in the variation of the fatigue strength in the radial direction of the forged product and excellent in the fatigue properties, and to provide a crankshaft manufactured from the forged product. SOLUTION: When the density (D 0 ) of the inclusions whose major axis exceeds 5 μm observed in the axis position of a cross section perpendicular to the axial direction of the forged product is made 70 nos/cm 2 or below and the radius of the forged product is made R, the ratio of the density (D R ) of the inclusions whose major axis exceeds 5 μm observed in the R/3 position from the axis position toward the radial direction and the density D 0 satisfies an inequality (1) below. (1) 0.5≤D R /D 0 ≤1.50. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To smoothly perform upset forging by suppressing an elongation amount caused by reduction by an anvil without impairing the efficiency of reduction by the anvil.SOLUTION: When the reduction of a forming blank 4 is carried out and an elongation amount L1 of the forming blank 4 after the reduction is large and the elongation amount L1 is out of a halfway specified range, the anvil 3 is rotated and the reduction by the anvil 3 is started, and reduction by the rotation of the anvil 3 is continued until the completion of upset forging. When the elongation amount L1 is within the halfway specified range, the reduction speed is changed, and the reduction of the forging blank 4 is carried out without rotating the anvil 3.
摘要翻译：要解决的问题：通过抑制由砧座的减少引起的伸长量而不损害砧座的减小效率，来平稳地进行锻造锻造。解决方案：当进行成形坯料4的还原并且还原后的成形坯料4的伸长量L1大并且伸长量L1在中途规定范围之外时，砧座3旋转，开始砧座3的减少，并且通过砧座3的旋转继续减少直到锻造完成。当伸长量L1在中途规定的范围内时，减速速度发生变化，并且锻造坯料4的减少在不旋转砧座3的情况下进行。（C）2013，JPO＆INPIT
