description: Purpose of work: to develop and implement a technology for casting Â«Sector of the reference ringÂ» providing a reduction of gas, shrinkage and non-metallic inclusions defects, based on computer simulation of the process of forming the casting. The tasks that were solved during the study: analysis of the quality of castings from chromium - nickel alloy "at LLC" IZ - KARTEX"; development of proposals to improve existing technology; modeling processes input, solidification of casting and the formation of shrinkage defects using the proposed technology. The causes of damage to castings from low-carbon chromium-nickel steel by gas, shrinkage and non-metallic inclusions defects during the implementation of the current technology operating at the enterprise are identified and analyzed. The main reason for the defect is the position of the casting in the mold and the design of the gate-feeding system, which is confirmed by the simulation results using the MagmaSof package of processes for filling the mold with the melt, solidifying the casting and forming defects using the existing technology. Fundamental changes are proposed in the technology of casting production related to the change gate-feeding system and the location of the casting in the upper half-mold. The effectiveness of the developed proposals is confirmed by the simulation results and finished casting.
