进入80年代以来,烧结、球团和炼铁生产发展的主要特点是:通过对现有企业的现代化技术改造,继续提高产品质量,降低能耗和实现生产工艺过程自动化。在80年代前半期,新建设备不多,只建了几座高炉和几个生产直接还原用原料的球团厂。这些新建设备多数在发展中国家。 Since the 1980s, the main features of the development of sintering, pellet and ironmaking production have been to continue to improve product quality, reduce energy consumption and automate the production process through the modernization of existing enterprises. In the first half of the 1980s, there were not many newly built facilities. Only a few blast furnaces and several pelletizing plants for producing direct reduction materials were built. Most of these new equipment is in developing countries.
