世界钢铁冶金的发展越来越强烈地受能源杠杆的制约。在原料方面,高能耗的生铁产量受“零能”原料废钢用量的影响,并与之成反比;在工艺方面,大型、高功率的节能炉如超高功率电炉得到迅速发展;在产品方面,由于电炉冶炼使用废钢,具有产品综合能耗低的优点,其产量的增长速度最大。因此,在近阶段钢锭的获得,除适用品种的需求外,主要应考虑两大因素:前工序能耗即原料能耗和本工序能耗。本文以此为出发点进行探索,期望得到能适合于我国国情的 The development of world iron and steel metallurgy is increasingly constrained by energy levers. In terms of raw materials, the production of high-energy-consumption pig iron is affected by the amount of “zero-energy” raw material scrap and inversely proportional to it. In terms of technology, large-scale and high-power energy-saving furnaces such as ultra-high power electric furnaces have been rapidly developed; in terms of products, As the use of scrap smelting furnace, with the advantages of low energy consumption of integrated products, the largest increase in output growth. Therefore, in the near-term access to steel ingot, in addition to the needs of the applicable varieties, the two main factors should be considered: the first process energy consumption that raw materials and energy consumption of the process. This article takes this as a starting point to explore, expecting to be suitable for our national conditions
