摘　　要：针对６００ＭＷ汽轮机高压主汽调节阀阀体设计和制造的难点———封闭内孔，采用了强制冷却技术和钢质外壳芯等措施。实践表明，所进行的工艺设计是合理的，尤其是对封闭内孔所采取的措施是成功的，收到了预期的效果，为该类大型铸钢件的设计和制造探索出了一条新路。In order to overcome the difficulty——design and manufacture of internal hole, the techniques of forced cooling and steel cased core ware adopted. The analyses and summarizations of manufacture process show that the process design was proper, especially the mensures to the internal hole was successful and acquired the expected results. A new way for this kind of large steel casting has been proposed.
