Casting Process Design and Optimization of Turbine Runner Body
摘要
Abstract
The process characteristics of low alloy steel turbine runner body by sodium silicated-bonded sand are studied; the casting process is designed and optimized. The casting is modeled by SolidWorks software, and the flow field and temperature field of the casting filling process are simulated by AnyCasting software. The final casting process is determined, and verified by experiments. The results show that adopting stepwise pouring way can ensure the melt being filled smoothly and completely. The shrinkage and dispersed shrinkage of the casting can be efficiently eliminated by using of riser and chill. With optimal process scheme, the casting of low alloy steel turbine runner body is totally shaped and has a legible contour, and there are not obvious casting defects in the casting.关键词
