摘要
近年来,由于国内外优质的矿石和炼焦煤资源日益紧张,为保证高炉稳定顺行,攀钢在冶炼钒钛磁铁矿技术的认识上有了新的技术理念,树立高炉"均衡稳定"生产为目标。为此,在入炉原料的"精料"工作上进行技术攻关,采用合理的炉料结构,优化入炉原料的处理控制技术,提高鼓风动能的同时,合理进行"上下部调剂"等有效的技术措施。2008年至2009年9月在综合入炉品位仅为50.39%的条件下,高炉的利用系数均达到了2.319t/m3.d,焦比降到468 kg/tp煤比达到116.22 kg/tp,烧结矿的入炉粉末降到了1.53%。
In recent years, due to the high quality ore and coking coal resources in the increasingly tense, in order to Yasumasa stable antegrade BF, Panzhihua V-Ti magnetite in smelting technology, a new understanding of the technical concepts and establish BF ＂balanced stability＂ production target,for which the raw materials into the furnace,＂ concentrate＂ the work of technical research, using a reasonable bur- den structure, optimize the processing of raw materials into the furnace control technology to improve blast kinetic energy at the same time, reasonable for ＂ upper and lower transfers＂ and so effective technical measures. From 2008 to september 2009 integrated into the furnace grade of only 50. 39% of the conditions,the blast furnace utilization coefficient are to 2. 319 t/m3 · d,coal, coke down 468 kg/tp ratio of 116. 22 kg/tp,sintering ore into the furnace powder down to 1.53%.
