传统的冲天炉配料方法都是旨在保证铸铁获得合格的化学成分及机械性能,而不太考虑炉料成本,一般都采用手工计算.但是,为了提高经济效益,增强竞争能力,就应该在配料时也考虑降低铸件成本问题.为此,在配料计算时,应该利用一种数字方法——线性规划,这种方法可以在保证铸铁性能和化学成分的条件下,使所配炉料的成本最低.单纯形法是线性规划中最常用的解法,它可以根据炉料的化学成分和配料要求,很容易地建立起数字模型.不过由于数字方程式较多,采用手工计算就会非常繁琐而且极易出错,而用电子计算机
Traditional methods of cupola ingredients are designed to ensure that cast iron get qualified chemical composition and mechanical properties, and do not take into account the burden of charge, are generally calculated by hand, but in order to improve economic efficiency and enhance competitiveness, it should be in the ingredients Also consider reducing the cost of castings.To this end, in the calculation of ingredients, you should use a digital method - linear programming, this method can guarantee the performance of cast iron and chemical composition of the conditions, The shape method is the most common solution in linear programming and it can easily set up a digital model based on the chemical composition of the charge and the ingredients required, but because of the large number of equations, manual calculations can be cumbersome and error-prone Using a computer
