一、总的原则:1．内浇口总截面积的计算公式F——内浇口总截面积(公分2)O——铸型内金属的重量(公斤)N——条件系数,由kV值按表1确定L——流动性校正系数,由表2确定
First, the general principle: 1. The total gate area of the formula F - the total gate area (cm 2) O - the weight of the mold metal (kg) N - the coefficient of condition determined by the value of kV 1 Table L - Liquidity correction coefficient, determined by Table 2
