摘　　要：通过比较,找出了顶注、侧注、底注法各自的优缺点,从而认定,对内在质量要求严格的中小件宜采用顶注,对结构复杂的大而薄的铸件宜采用底注,下1/3处侧注及阶梯浇注系统是适用性最广、应用最多的浇注方式。通过生产实例进行了说明。In this paper, three different pouring processing was compared, including top pouring, side pouring and bottom pouring. The top pouring processing is suitable for medium and small casting. Bottom pouring, 1/3 bottom side pouring and step gating system are more fit for large thin-thickness complex casting. The results were illustrated by practical examples.
