高炉日趋大型化和大幅度降低焦比是十多年来炼铁生产在技术上的显著进展,为此,必须相应地对冶金焦炭质量提出更高的要求。为了适应我国钢铁工业大幅度稳步上升的需要,我们必须对我圈冶金焦炭质量现状及其差距有所了解,进而寻求改善冶金焦炭质量的途径。 Increasing large-scale blast furnace and a substantial reduction of coke ratio is a significant technological advance in iron-making production for more than a decade. To this end, higher demands must be placed on the quality of metallurgical coke. In order to meet the needs of a large and steady increase of China’s steel industry, we must understand the status quo and the gap of metallurgical coke quality in our area, and then seek ways to improve the quality of metallurgical coke.
