铝合金铸件成本报价速算法

Rapid Calculation Method of Quoted Price for Aluminum Alloy Castings Costs

以中等复杂一般要求的ZL101-T4典型铸件为案例,以铸件总成本中占主导地位的"单位铸件材料消耗定额"单项成本作为基准成本"A"(本案例A=18.16元/kg),以此求出其余各成本以及利润、应纳税费额等占基准成本A的比例系数,相加全部系数得到铸件报价系数F=2.0501。由于铸件复杂程度和工艺难度不同,其工艺成本亦不同,引入铸件调价系数K(K=0.90～1.30)以适应各类不同铸件的速算报价需要,其速算公式为:铸件总报价Q=2.0501AK(元/kg)。

In this paper, the medium-complex ZL 101-T4 typical castings with general requirements were taken as case. The ＂unit casting material consumption quota＂ that dominates the total cost of single casting is regarded as the baseline cost ＂A＂ （in this case, A=18.16 Yuan RMB/kg）. The proportions coefficients of the rest costs, profits, and the amount of payable taxes etc. account for the baseline cost A can be obtained through ＂A ＂, which were added to obtain the quote coefficient F=2.050 1. Because of the different complexity and process difficulty of casting, the process cost is also different, so the casting price adjustment coefficient K （K=0.90-1.30） is introduced to adapt the needs of the rapid calculation method of the various types of casting. The rapid calculation formula is Q=2.0501A K （Yuan RMB/kg） .
