一、前言考察现代热连轧带钢厂的生产成本总费用中,直接能耗的费用,即连续加热炉燃料消耗的费用和轧制线电耗的费用所占的比值最大。过去对轧钢生产的要求,主要是提高产量,提高轧机生产总值。而如今,虽然这些要求仍很重要,但由于世界能源出现危机,燃料价格上涨等因素,对于节能方面的要求变得更为重要,日趋突出。这些要 First, the preface To examine the total cost of production costs of modern hot strip mill, the direct energy consumption costs, that is, the cost of continuous heating furnace fuel consumption and rolling line power consumption accounted for the largest ratio. In the past, the requirements for rolling production were mainly to increase the output and increase the total mill output. And today, while these requirements are still important, the demand for energy efficiency has become even more important and prominent due to the world energy crisis and the rising fuel prices. These are
