我国鞍钢、本钢几家烧结厂早在五十年代初,就开始配用消石灰或生石灰(配3％左右),主要是作为粘结剂,以改善细精矿的成球性能;在提高烧结矿的产量方面取得了一定的效果。但这一新技术的发展和提高很缓慢;国内只有马钢在生石灰的焙灼、制备、环保和生产使用上取得了新的成绩。如今国外在烧结富铁矿时也添加了生石灰,日本为宝钢设计并提供的450m~2烧结机,其设计主要或全部用富矿粉,也考虑了添加生石
China’s Anshan Iron and Steel, Bengang several sinters as early as the early 1950s, began to use with slaked lime or quicklime (with about 3%), mainly as a binder, to improve the quality of fine ore into the ball; improve the sintering Mine production has achieved some results. However, the development and enhancement of this new technology is very slow; only China Masteel has made new achievements in the roasting, preparation, environmental protection and production and use of quick lime. Today, foreign countries also add quicklime when sintering iron-rich ores. The 450m ~ 2 sintering machine designed and supplied by Baosteel in Japan is designed mainly or entirely with rich ore powder,
