Abstract：
Medium pressure cylinder is a key component of steam turbine thermal power unit,which has high requirements for materials,mechanical properties and nondestructive testing.In order to produce qualified medium pressure cylinder castings,the rational design of casting system,riser calculation and material control method were introduced by means of virtual inspection technology.The high quality castings with qualified mechanical properties and nondestructive testing are successfully produced.
