Cold forming technology of steel lining strengthened nodes in HPR 1000
In order to solve the problems of low working efficiency,unstable quality and high manufacturing cost in the prefabrication process of steel lining reinforced joint,according to the structural characteristics of steel lining reinforced joint,the integral cold bending forming process was proposed,and the key technical points of cold bending forming of steel lining reinforced joint were obtained by selecting reasonable process parameters and equipment and carrying out forming process tests.The machining precision and efficiency of components were improved,the processing quality was ensured,and the engineering cost was reduced,which provides reference experience for the subsequent construction of the like or similar structure of nuclear power reactors.
