description: The theme of the graduation qualification work: "The effect of uneven difficult shrinkage on the quality of typical cast iron and steel castings". This work is devoted to the study of the influence of uneven difficult shrinkage of typical cast iron and steel castings and the development of a method for accounting for uneven difficult shrinkage in order to reduce the labor intensity of casting production, as well as reduce metal consumption. Tasks to be solved in the work: 1. Quantitative assessment of the effect of non-uniform shrinkage on the geometric characteristics of typical castings. 2. Quantification analysis. 3. Development of recommendations for improvement of consideration of influence of uneven difficult shrinkage on dimensional accuracy of castings. The work revealed a problem concerning the unevenness of the difficult shrinkage, which affected the dimensional accuracy of castings, increasing the labor intensity of the production process of products, as well as increasing the consumption of metal. Based on the production of Harmony LLC, a quantitative assessment and analysis of the effect of non-uniform shrinkage on the geometric characteristics of three typical castings was carried out. A method was developed to account for uneven difficult shrinkage and reduce production losses.
