Abstract

Using a computer program, the process of forming shrinkage defects is simulated, in parallel with the use of exothermic inserts, in order to increase the efficiency of feeding the casting and reduce metal consumption on profits. At the same time, a reasonable choice of the design of profits is of great importance, as well as the calculation of their minimum permissible sizes used at the current production in the manufacture of the "Side Frame" casting of railway cars.
