Then, the calculation methods of overall forging ratio are comprehensively compared with practice in nuclear power project. This has some guiding significance for technical preparation and quality control of large forgings for nuclear island. Key words : large forgings for nuclear island; forging ratio; overall forging ratio; quality control 核电站反应堆压力容器、主泵、稳压器、蒸汽发 钢锭直接锻造而成。 钢锭的内部会存在疏松、缩孔、 生器
