| Abstract: | Amounts of thin-walled castings have been used in aerospace,spaceflight and defense technology industry.The vacuum counter-pressure casting technology has been extensively employed to the production of high quality thin-walled components due to the advantage of filling and solidification.The vacuum counter-pressure casting thin-walled components have attracted much attention at home and abroad.The recent research progress in the control system of vacuum counter-pressure casting,filling behavior and solidification process of thin-walled castings were described.The grade-pressure control system of vacuum counter-pressure casting,filling behavior models,microstructures and feeding capacity of vacuum counter-pressure casting were introduced in detail.Finally,the existing problems were put forward and the future prospect was presented. |
