Several cylindrical castings with different modulus and size of riser necks cast in furan bonded silicon sand molds are examined and analyzed numerically.
在呋喃树脂砂型条件下，针对不同模数、不同冒口颈尺寸的圆柱试样进行了模拟计算和浇注试验。

There are two methods to design riser for steel casting, one is proportion method, and the other is modulus method.
设计方法采用比例法和模数法，实现了常用冒口的设计。
