description: The topic of the final qualifying work: "Investigation of the influence of silicon-free ligatures on the casting and mechanical properties of structural steels". This work is devoted to comparing the effect of silicon-free ligatures of the grades ÐÐÐ¦Ðµ, ÐÐÐ¦ÐµÐ¢Ð and ÐÐ¦ÐµÐ on the casting and mechanical properties of steels 110Ð13Ð, 20ÐÐ¡Ð, 20Ð¥ÐÐÐ¢Ð¤Ð. Tasks that were solved during the study: Receiving and preparing samples; Conducting research on the casting properties of steels: liquid fluidity, linear shrinkage, crack resistance. Conducting research on the mechanical properties of steels; Analysis and comparison of the results obtained. The influence of silicon-free ligatures of the ÐÐÐ¦Ðµ, ÐÐÐ¦ÐµÐ¢Ð and ÐÐ¦ÐµÐ grades on the following grades of structural steels was analyzed: 110Ð13Ð, 20ÐÐ¡Ð, 20Ð¥ÐÐÐ¢Ð¤Ð. Studies were carried out on fluidity, linear shrinkage, crack resistance and mechanical properties, as well as a comparison of the results obtained. In conclusion, conclusions are drawn about the improvement or deterioration of casting and mechanical properties with the addition of appropriate ligatures.
