摘　　要：评述轮类铸铁件砂型铸造中,一些工厂较常采用的一些传统铸造工艺:中部分型—轮缘切线进液工艺、顶部分型—轮缘切线进液工艺、顶部分型—轮缘耳冒口进液工艺,以及雨淋式浇口工艺存在的不足;阐述了轮类铸铁件采用新颖的压边浇(冒)口铸造工艺的优化设计指导理论和技术要点,简评了压边浇(冒)口铸造工艺在轮类铸铁件上应用所获得的良好技术经济效果。Some foundry technologies widely used to produce iron castings of wheels are reviewed in this paper. The shortcomings of these technologies, such as parting at middle plane tangent pouring at flanges, parting at top plane tangent pouring at flange, and parting at top plane pouring at risers of flange, are commented. The basic theory and technical points of a new kind of lap gate （riser） adopted to produce iron castings of wheels are discussed and good economic results of this technology in production are also presented.
