A study was conducted to reduce defects in especially critical cast large-sized parts of freight car bogies. The side frame was used as the part under study. The main factors influencing the formation of hot cracks in large steel castings are presented. To avoid the rejection of steel castings, the use of heat-insulating mixtures to reduce hot cracks has been investigated. The temperature distribution of the melt along the height of the ladle is modeled. An analysis of the influence of the order of pouring molds and pouring temperature on the number of hot cracks in the side frames is presented.
