本文阐述了钢轨接触焊焊缝采用电感应加热正火后,其塑性、冲击韧性、静弯性能均大幅度提高。证明了正火感应器及其工艺对钢轨全断面正火的良好效果。 This article describes the rail contact welding seam after induction heating normalizing, its plasticity, impact toughness, static bending performance are greatly improved. It proves that the normalized inductor and its technology have a good effect on normalizing the entire cross section of the rail.
