Two casting examples are given in this article showing that shrinkage problems in the castings were solved using proportional solidification theory, specially using thin, wide and short rectangular riser neck. 用实例给出运用均衡凝固理论,特别是薄、宽、短矩型冒口颈解决英国铸造厂球墨铸铁件的缩孔问题。
The side riser through which liquid metal flowed to the mold cavity was used, thus the dimension of the riser and its neck could be minimized and the casting yield could be increased. 采用侧冒口工艺,金属液流经冒口进入型腔,减小冒口及冒口颈尺寸,提高工艺出品率。
