【Abstract】 This paper expounds the assembly of integral-shrouded blade and free standing blade for 650MW nuclear turbine. By measuring and controlling the radial line of free standing blade and integral shrouded blade with P type root, we can make the load-carrying surface on both sides of root tightly contacted and evenly loaded, thus precisely ensures the through-flow clearance.更多还原
