【Abstract】 The control poles for driving machine in the built and building nuclear power station are made of thick wall 1Cr13 tubes which all depend on overseas importation.With the fast development of domestic nuclear power stations and the need with coming export,as one of the key parts of driving machines,the 1Cr13 tubes used as control poles should be finished in our country.By optimizing the contents of C,Ni,Cr,H,O and N etc.,and adjusting the technology of cold rolling, the cracking problem of 1Cr13 tube as control poles during machining is avoided and favorable surface quality is also obtained.The mechanical properties of finished tubes reach the technical request after proper heat-treatment.更多还原
