为了降低烧结工序的环境污染和能耗,提出了生产高镁碱性球团的构想。通过研究不同碱度条件下球团矿的抗压强度变化规律,得出R为1.0时高镁碱性球团的抗压强度最大(2 830 N/个);在此基础上又研究了熔剂种类对高镁碱性球团强度的影响,确定了白云石和石灰石搭配最佳,并分析了熔剂种类对高镁碱性球团矿显微结构的影响。
In order to reduce environmental pollution and energy consumption in the sintering process, a concept of producing high-magnesium alkaline pellets was proposed. By studying the variation law of compressive strength of pellets under different alkalinity conditions, it is concluded that the compressive strength of high-magnesium alkaline pellets is the highest (2 830 N / a) when R is 1.0. On this basis, The influence of different kinds of additives on the strength of high-Mg alkaline pellets was determined. The best combination of dolomite and limestone was determined, and the influence of flux types on the microstructure of high-magnesium alkaline pellets was analyzed.
