Manufacturing Technology of Mn-Ni-Mo Alloy Steel Heavy Forgings for HPR1000 Nuclear Power Plant
View through CrossRef
Abstract
HPR1000 nuclear power technology is the mainstream technology of commercial pressurized water nuclear power in China, which is adopted by most nuclear power plants under construction or planned. Mn-Ni-Mo alloy steel heavy forgings are widely used in the equipment of pressurized water nuclear reactor. In order to achieve the aim of safe operation for at least 60 years, the technical specifications of Mn-Ni-Mo alloy steel heavy forgings for HPR1000 are high and strict. Due to the high technology and difficult manufacturing, only a few factories have the manufacturing capacity of forgings with stable quality worldwide, which can’t meet the continuous growth demand of Chinese market. Therefore, whether Mn-Ni-Mo alloy steel heavy forgings can be delivered on time has become an important factor restricting the construction cycle of HPR1000 nuclear power plants.
In order to meet the market demand, Shanghai Electric SHMP Casting & Forging Co., Ltd (SCF) has developed the manufacturing technology of heavy forgings for HPR1000. According to the technical specifications of HPR1000, SCF has carried out systematic research in smelting, forging and heat treatment technologies. By 2020, SCF has realized the mass production of heavy forgings for HPR1000 nuclear power plant.
This paper reports new technologies obtained by SCF in the development of Mn-Ni-Mo alloy steel heavy forgings for HPR1000 nuclear power plant.
