description: Topic of the final qualification work: "Improvement of the technology for obtaining a casting "Korpus kartera" from SCH25 in order to cover surface defects and discontinuities". This work revealed the identification of the technological process for obtaining a typical casting at "GOZ" Obukhovskiy zavod and a lot of defects. Tasks that were drawn up and solved in the course of work: 1. Collection and comparative analysis of statistical data on the quality of a typical casting; 2. Identification of the causes of damage by surface defects in the form of sinks and discontinuity defects in the form of gas shrinkage cavities; 3. Development and implementation of recommendations for adjusting the technological process of casting production in order to attract defects.The work was carried out on the basis of "GOZ" Obukhovskiy zavod, where all the real material was collected: the technological process of obtaining a casting, the results of effective optical control of defects, data from chemical analysis and physical and mechanical tests. Based on the analysis of the casting detection technology, the reasons for the formation of defects were identified: insufficient feeding of the casting and exhaust gases. The results of experimental pouring technologies have been developed and confirmed using changes: the casting in the mold is turned over 180Â° (bottom up), exothermic equipment is installed and the gating-feeding system is changed.
