本文介绍一种简易、实用的灰口铸铁件浇注系统计算方法,它把铸件的重量作为计算的主要依据,把其它各种因素也适当考虑成经验修正数据,归纳成简单公式和图表.提出了暗冒口、压边浇口和雨淋浇口的浇注系统计算方法.经大量生产数据查核和验证,简易计算方法是切实可行的.可供从事铸造工作的工人、技术人员在实际工作中参考.(图3个、表2个) This paper presents a simple and practical method for calculating the casting system of gray cast iron. It takes the weight of castings as the main basis for calculation and considers various other factors into empirical correction data, which can be summarized into simple formulas and charts Dark riser, pressure side gate and rain gate pouring system calculation method.After a large number of production data checking and verification, simple calculation method is feasible.For workers engaged in casting work, the technical staff in the actual work reference (Figure 3, Table 2)
