摘　　要：叙述高铬白口铸铁件冒口设计程序和浇注系统的计算方法。以R.C.Creese的计算冒口公式为基础,以杂质泵泵壳为例,说明求解冒口尺寸的过程。介绍常用的几种强化冒口补缩的措施:采用保温冒口;浇注系统通过冒口;以及一个冒口补缩多个铸件。用所介绍的方法设计的保温冒口生产泵壳,铸件致密性良好。The riser design procedure and gating system calculation method of hi-chromium white cast iron castings was described. Based on the expression proposed by R.C.Creese for calculating the volume of the riser, and taking the riser design for a slurry pump housing as an example, the procedure of how determine riser dimensions was demonstrated. Some useful measures to intensify feeding effect of riser were introduced including： using thermally insulated riser; gating through riser; as well as using one riser to feed several castings. The riser designed such way has been applied to produce the castings, and result showed that the castings were satisfactorily sound.
