摘　　要：升液管是反重力铸造的关键部件之一,对铸件质量的控制具有非常重要的作用。综述了升液管升液的原理、材料的分类和近年来制造工艺的国内外研究进展。重点叙述了升液管在熔点较低的轻质合金以及熔点较高的钢铁材料和高温合金等反重力铸造方面的研究进展和应用情况,并对升液管今后的发展进行了展望。The riser tube is a key unit for counter-gravity casting, which plays very important role in controlling performance of castings. The principle of counter-gravity casting, the material classification of riser tube, the manufacturing methods of tubes in recent years at home and abroad are introduced, especially focusing on the development and application of tubes for cast light metal which has low melting point, cast iron and steel, superalloys and so on which have high melting points. And the development trend of the riser tubes was described.
