【摘要】 本文通过系统分析,建立了钢铁企业吨钢生产成本模型。通过某钢轧厂的实际生产数据验证,表明模型在计算钢铁企业吨钢生产成本方面基本准确。通过模型应用,获得在两种不同生产情况下,铁钢比对吨钢生产成本的影响规律,提出了废钢临界价格概念。结论表明,废钢收购价格高于临界价格,提高铁钢比可以降低吨钢生产成本,废钢收购价格低于临界价格,提高铁钢比吨钢生产成本升高。废钢收购价格与临界价格相差越大,铁钢比对吨钢生产成本影响越显著。实例计算表明,该企业废钢临界价格为2900元/吨,当废钢收购价格高于临界价格237元/t,铁钢比增加0.044时,吨钢生产成本降低了294万元左右(10.5元/t)。更多还原

【Abstract】 The model of iron and steel enterprise production cost per ton of steel was built through the systematic analysis. The cost model was proved to be accurate by contrast with actual production data of a certain steel rolling plant. The influence law of steel-iron ratio on the production cost per ton of steel has been obtained by means of the application of mathematic model in two different production conditions. And this paper put forward the notion of the scrap critical price. The results show that the production cost per ton of steel will drop with steel-iron ratio increasing when scrap purchase price is higher than scrap critical price. Contrariwise the production cost per ton of steel will increase with steel-iron ratio increasing when scrap purchase price is lower than scrap critical price. A example result show that scrap critical price is 2900yuan/t. The total cost was reduced by 294 million yuan/t(10.5yuan/t) when the scrap purchase price was higher than scrap critical price 237 yuan/t and steel-iron ratio increased 0.044.更多还原
