The invention provides a thermal treatment induction device for a T30C-specification ball flat steel and a thermal treatment method. By tempering a quenched sample through a quenching process simulation test, and performing mechanical property detection to confirm reasonability of the thermal treatment induction device and the thermal treatment method, so that a reasonable induction device and a reasonable thermal treatment method are obtained. The induction device is formed by bending a hollow copper tube, and a joint of the induction device and a power supply is equipped with a pedestal madeof a copper plate; a matched induction ring arc-shaped dimension is adopted according to the shape of T30C ball flat steel, so that processing needs of the T30C-specification ball flat steel can be met; in a length direction, a closed loop is formed, a hollow part water receiving tube in the induction device cools, and a spraying tube and a cooling tube can accomplish uniform quenching of a workpiece. The thermal treatment induction device is simple in structure, is convenient in operation, can synchronously quench, and is suitable for being applied as the thermal treatment device and the thermal treatment method. The quenched ball flat steel is high in performance qualification rate.
Description
technical field [0001] The invention relates to medium-frequency induction heat treatment in the field of metal thermal processing, in particular to a heat treatment induction device and a heat treatment method for T30C standard spherical flat steel. Background technique [0002] (l), medium frequency induction hardening is to use electromagnetic induction to generate eddy current in the workpiece to heat the workpiece, which is one of the common metal surface heat treatment methods. Ordinary induction coils are made of bent ring-shaped hollow copper tubes. When the copper tubes are powered on, an electromagnetic field is generated in the ring-shaped hollow copper tubes, and the workpiece in the ring will be heated rapidly. The annular hollow copper tube is passed with circulating cooling water to cool the copper tube to prevent burning. After the workpiece is heated, it must be quenched in the quenching medium. The quenching effect is not good and energy is wasted, or anot...
