冲天炉图解法配料最优化是研究保证铸铁化学成分的前提下,使炉料成本最低的图解法配料.它可以不使用电子计算机,适合于中小工厂,1983年7月黑龙江国防工办主持了鉴定,在哈尔滨建成厂、哈尔滨重型厂、哈尔滨汽轮机厂使用每吨炉料成本下降8～12.5元/吨。图解法内容:一、配料最优化的数学表达式,把满足成分要求和炉料成本最低,用数学公式表达出来。二、用图解法解出生铁、旧炉料和废钢的配料范围。三、解法的数 Cupola diagram ingredients optimization is to study to ensure that the chemical composition of cast iron under the premise of the burden of the lowest burden of the graphic method ingredients.It can not use the computer, suitable for small and medium-sized factories, in July 1983 Heilongjiang Defense Office presided over the identification, Harbin built plant, Harbin Heavy Duty Factory, Harbin Steam Turbine Plant per ton of charge costs down 8 ~ 12.5 yuan / ton. Schematic content: First, the mathematical optimization of ingredients expression, to meet the composition requirements and charge the lowest cost, expressed in mathematical formula. Second, the graphical solution to the pig iron, the old charge and scrap steel ingredients range. Third, the number of solution
