摘　　要：本文研究了一种新型的反重力铸造法—智能控制的真空变压反重力铸造薄壁铸件的充型机理 ,并对智能控制的真空变压反重力铸造和重力铸造分别铸造 0 .8mm、1.5mm、2mm的铝合金薄壁铸件的充型能力进行了比较。研究结果表明 ,真空变压反重力铸造能实现金属液平稳充型 ,具有良好的充型流体力学条件 ;真空变压反重力铸造0 .8mm、1.5mm、2mm的铝合金薄壁件全部充填完整 ,具有良好的充型能力。The filling mechanism of a new counter-gravity casting method--vacuum various pressure counter-gravity casting thin-wall castings is studied.And the vacuum various pressure counter-gravity casting and the gravity casting to cast 0.8 mm?1.5 mm?2 mm aluminum alloy thin-wall castings were investigated. The study indicated that the vacuum various pressure counter-gravity casting could realize filling mould of metal liquid to stabilize and provided a good condition of the filling mould hydrodynamics. 0.8 mm?1.5 mm?2 mm aluminum alloy thin-wall castings of vacuum various pressure counter-gravity casting filled completely and it provided a good capacity of the filling mould.
