| Abstract: | The SA-508-3-1 ingot steel smelting process of EBT smelting-LF refining-VD-VC has been put forward by analyzing the difficulties of smelting process based on the characteristics of steel structure and property requirement for nuclear plant reactor pressure vessel.The nuclear power SA-508-3-1 ingot steel has been produced successfully according to this steel smelting process.The property of the forgings has reached the requirement of NRPV forgings after forging and heat treatment processes which helped CITIC HEAVY INDUSTRIES to be certified by National Nuclear Safety Administration. |
