由于炼铁技术的发展与市场经济的需要,烧结厂从1988年开始使用进口矿粉烧结,近两年烧结厂搭配进口矿粉已占铁料50%左右。但由于采购资金与铁路运输等诸多因素的影响,1998年大量使用印度矿粉,在烧结和炼铁生产中产生不良影响。特别是1998年9月初和11月份影响最为严重,当时烧结厂配用印度矿粉约占铁料的50～55%,使烧结矿产量与质量大滑坡,炼铁4座高炉利用系数受到一定的影响,后靠紧急调节部分澳矿粉和南非矿粉才逐步恢复正常。因此,有必要对进口矿粉的物理冶金
Due to the development of ironmaking technology and the needs of the market economy, the sintering plant has been using imported slag for sintering since 1988, and the sintering plant with imported slag has occupied about 50% of the iron content in the recent two years. However, due to the influence of purchasing funds and railway transportation, extensive use of Indian ore powder in 1998 adversely affected the sintering and ironmaking production. Especially in early September and early September 1998, the impact was the most serious. At that time, the sintering plant equipped with Indian ore accounted for about 50-55% of the iron content, so that the yield and quality of sinter, the utilization factor of blast furnace and the four blast furnaces were all certain Affected by the emergency adjustment after the Australian ore and ore powder South Africa gradually returned to normal. Therefore, it is necessary for the physical metallurgy of imported slag
