Abstract：Due to the structural stress, the hot crack defect of large heat-resistant steel castings is easy to appear, which affects the service performance of the castings. The application of AnyCasting numerical simulation software to predict the casting stress and design the gating system reasonably was introduced, so as to reduce the temperature gradient of the casting and eliminate the hot crack. It is verified that there is no hot crack defect in the thick area of the casting and it meets the requirements of performance.
