description: The topic of the final qualification work: Â«Comparative analysis of forging technologies on the example of rotary billetsÂ». This work is devoted to the description of the actual implementation of technologies for forging blanks of the rotor shafts and the analysis of the results of acceptance tests and additional studies of the quality of the metal. Tasks performed dured the work: 1. Development of forging technology and manufacturing of a rotor shaft blank. 2. Investigation of the quality of the ingot profit. 3. Analysis of the causes of defects, development of technologies to eliminate them. After the production of the forging using the technology of forging through a square on an octahedron, a study was made of the profit of an ingot of 142,0 tons. In the process of studying the structure and quality of the metal, it was found that a defect in the form of shrinkage porosity is often observed in the ingot in axial zone due to the influence of segregation of chemical elements, contamination of metal with non-metallic inclusions and pouring manifestations. In order to improve the quality of the usable metal, special forging technologies have been developed that are focused on eliminating a defect in the axial zone of the ingot. In this case, these are technologies: indentation (pressing head) and pressing with cooling (through the plate).
