动态模数法在大型铸钢件冒口设计中的应用

Design the Risers of Large Scale Steel Castings With the Trends-Modulus Method

依据动态模数理论建立有关冒口尺寸的三次方程，用二分法在计算机上进行数值求解，可快速计算出冒口尺寸．该法在实际生产中运用，获得了满意的效果．

According to the theory of trends-modulus,the cubic equation about a riser dimension was establishedand wes solved by dichotomy in a computer. By this method the dimension of riser can be obtained swiftly and satisfyingly in practical uses.
