1979年以来,由于烧结厂不断改进烧结工艺和操作技术,提高了烧结矿碱度,烧结矿冶金性能有了一定程度的改善。与此同时,炼铁厂也逐步实现了烧结矿沟下过筛,不断改进筛分设备,提高筛分效率,使烧结矿入炉粉末明显降低。原料条件的改善,对稳定高炉炉况,提高生产水平创造了有利条件。但是为了促使高炉生产创造新水平,突破武钢四座高炉年产400万吨,武钢烧结矿质量还存在着不少有待研究的具体问题。我们根
Since 1979, due to continuous improvement sinter sintering process and operation technology, improve the basicity of sinter, sinter metallurgy performance has been improved to some extent. At the same time, the iron ore mills have also gradually realized screening of sinter ditches, continuously improving the screening equipment, improving the screening efficiency and obviously reducing the sintering powder into the furnace. The improvement of raw material conditions has created favorable conditions for stabilizing the furnace condition and raising the production level. However, in order to promote the production of blast furnace to a new level and break through the four blast furnaces of WISCO with an annual output of 4 million tons, there are still many specific problems to be studied in the quality of sinter in WISCO.
