Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with specific embodiments.

[0021] An assembly line manufacturing method for large ring forgings, the method steps are as follows: blanking → rotary heating → forging and rolling ring → deformation quenching → water immersion flaw detection → tempering → machining;

[0022] (1) In the blanking process: CNC sawing machine is used to cut the steel material, and the steel material used for blanking is SCM440 or 4140;

[0023] (2) In the rotary heating process: use the automatic rotary heating furnace to heat the billet obtained from blanking, the steel billet obtained from blanking is conveyed by the conveying roller table, and then hoisted by the manipulator to the feed port of the automatic rotary heating furnace, the automatic rotary heating furnace adopts Regenerative oxygen-lean combustion, the automatic rotary heating furnace is divided into seven heating zones with gradually increasing t...
