Beschreibung
Zusammenfassung:	The invention relates to a novel train wheel integral-quenching technology. The novel train wheel integral-quenching technology comprises the following steps of 1, putting a workpiece into a lower vacuum heat-insulation mold cavity and a lower positioning mold cavity and dropping an upper compression mold and an upper vacuum heat-insulation mold cavity so that the upper vacuum heat-insulation mold cavity and the lower vacuum heat-insulation mold cavity clamp the workpiece, 2, fast dropping the integral-quenching device clamping the workpiece so that the device is immersed in a quenching cooling medium, and vertically and horizontally moving the integral device along with quenching cooling medium jet flow stirring, and 3, after cooling, integrally lifting the device, lifting the upper compression mold and the upper vacuum heat-insulation mold cavity and unloading the workpiece. In the novel train wheel integral-quenching process, a train wheel integrally enters into the quenching medium along with the molds, d
