[0013] To implement the billet forging method of 1Cr10Co6MoVNb steel according to the present invention, it is necessary to provide equipment such as a high-temperature heating furnace, a press, and a manipulator. The specific implementation is as follows:
[0014] The main chemical element content (weight percentage) of 1Cr10Co6MoVNb steel is: C content 0.06% ~ 0.11%, Mn content 0.60% ~ 1.15%, Si content 0.10% ~ 0.70%, Cr content 9.80% ~ 11.20%, content Ni content 0.20%~0.80%, Mo content 0.50%~1.00%, V content 0.10%~0.35%, Nb content 0.20%~0.45%, Co content 5.00%~7.00%, B content 0.004%~ 0.012%, N content 0.010% ~ 0.35%, S content ≤ 0.020%, P content ≤ 0.020%, the balance is Fe.
[0015] The blank forging process steps of 1Cr10Co6MoVNb steel are as follows:
[0016] Take 1Cr10Co6MoVNb steel ingot with a size of Φ600mm×780mm (about 1.5 tons); put 1Cr10Co6MoVNb steel ingot into a heating furnace with a furnace temperature of 750°C and keep it warm for 120 minutes; Uniformly ...
