Example Embodiment
[0026] Example 1
[0027] The engine high-pressure common rail forging in this embodiment includes a rail body with an axial channel and a plurality of radial pipes forged together with the rail body; the material of the forging is low alloy steel, specifically The content of C in the low alloy steel is 0.30wt%, the content of Si is 0.35wt%, the content of Mn is 0.72wt%, the content of Cr is 0.44wt%, the content of Mo is 0.15wt%, and the content of V is 0.16 wt%, Ti content is 0.015wt%, Al content is 0.015wt%, Ni content is 0.12wt%, P content is 0.012wt%, S content is 0.010wt%, the balance is Fe and unavoidable 的impurities. The low-alloy steel smelting method is prepared by the method of electric furnace + external refining + vacuum degassing. The forging is processed by the rapid cooling zone, the stable zone and the slow cooling zone to realize the heat treatment of the high pressure common rail forging. During heat treatment, place the forgings in accordance with the prescr...
