Abstract：
In order to reduce the production cost, shorten the production cycle and improve the production efficiency, the technical scheme of sand mold casting production is determined according to the structural characteristics, working conditions and casting process requirements of hydraulic turbine volute casing. On the basis of this, the corresponding casting process parameters and gate system of hydraulic turbine volute casing were formulated, and the solidification simulation was carried out using Any-Casting software. The results show that the simulation results are more objective and accurate. According to the defects of shrinkage cavity and shrinkage cavity of casting, the feasibility of using sand casting method for hydraulic turbine volute casing is determined by changing the riser parameters and adding cold iron to optimize casting process.
