7.5kw AC Semi Trailer Axles Kingrail OEM ODM For Freight Wagon

For 7.5kw AC Semi Trailer Axles Kingrail OEM ODM For Freight Wagon, Kingrail  railway axle heat treatment system includes a cooling device, a normalizing device and a tempering device. The cooling device and the inlet of the normalizing device are connected through a roller table, and the outlet of the normalizing device and the inlet of the tempering device are connected through the roller table. The beneficial effect of the present invention is that the normalizing device is connected with the tempering device to realize continuous production of different process routes, and the cooling device is provided to cool the axle, and can improve the cooling speed and production efficiency.

A steel material for an axle and a processing method thereof belong to the field of metal smelting and processing. Contains the following ingredients: 0.46～0.58wt% of C, 0.17～0.40wt% of Si, 0.75～1.00wt% of Mn, ≤0.015wt% of P, ≤0.010wt% of S, 0.18～0.25wt% of Ni, 0.20 to 0.27 wt% of Cr, ≦0.15 wt% of Cu, ≦0.10 wt% of Mo, 0.02 to 0.08 wt% of V, 0.015 to 0.045 wt% of Al, etc., with the balance being Fe. The process flow of the present invention is: electric furnace smelting or converter smelting → LF furnace refining → RH or VD vacuum treatment → continuous casting → slow cooling or hot delivery → forging heating → hydraulic press forging billeting → forging billet heating → rolling → slow cooling →Normalizing and tempering. Therefore, the shaft material produced by KINGRAIL is dense and uniform.
