水钢烧结矿烧结强度影响因素的试验研究

Study on the Factors Influencing Sinter Strength at Shuigang Sintering Plant

通过烧结杯试验和对转鼓指数的测定研究了铁料、碱度、燃料消耗和水分等因素对水钢烧结强度的影响。通过光学显微镜分析表明,合理控制铁料搭配、燃耗、碱度和物料水分等条件,可以生成较多的铁酸钙和铁橄榄石,得到以熔蚀结构或粒(板条)状结构为主的烧结矿,可以有效的提高烧结矿强度。通过大量的试验研究得到了较好的实验效果。

The influence of iron materials, alkalinity, fuel consumption and moisture on sinter strength were studied through the sintering cup test and the drum index test. The analysis of optical microscope indicates that through the reasonable iron material proportioning, alkalinity, fuel consumption and moisture to promote the calcium ferrite and iron olivine formation, and to obtain the melting corrosion structure or the granular structure as primarily sinter, the sinter strength could be effectively increased. Through a great quantity test research, good experiments results were obtained.
