摘要： A steel-member manufacturing facility that can suppress distortion occurring in a quenching process while preventing increase in manufacturing cost includes: a die-cutting apparatus to form a washer; a high-frequency induction heating apparatus for quenching purpose as well as a mold-constraining cooling apparatus that heat the washer as formed and thereafter cool the washer so as to quench-harden the washer; and a high-frequency induction heating apparatus for tempering purpose that heats the quench-hardened washer so as to temper the washer. The high-frequency induction heating apparatus for quenching purpose can heat the washer by induction heating to the temperature of at least Ac1 point. The mold-constraining cooling apparatus uses a mold to constrain the heated washer while using the mold as a cooling member, thereby cooling the washer to the temperature of at most Ms point.
