摘　　要：为了找到不同熔剂之间的适宜搭配,研究不同熔剂之间的两两搭配对生球强度、爆裂温度及抗压强度的影响规律,探索镁质熔剂性球团适宜的焙烧区间;并结合factsage软件确定适宜的液相量,借助XRD分析镁质熔剂性球团的矿相组成阐述了抗压强度变化规律。结果表明:四种不同熔剂搭配时,生球强度均能满足生产需求,高镁粉和高钙粉搭配时,爆裂温度最佳达560℃;高镁熔剂性球团适宜的焙烧温度为1 240℃,适宜的焙烧段较窄约为20℃,且该球团适宜的液相量为5%左右。In order to find the appropriate flux, the different types of flux matching is studied with to their influence on green pellet strength , burst temperature and compressive strength. And the respect suitable roasting interval of the magnesian flux pellet was investigated and the appropriate amount of liquid phase was determined by factsage software. Mineral phase composition of magnesian flux XRD to find out the evolution law of compressive strength. The results show the pellets was analysed by strength of green ball with addition of all four different flux type matching can satisfy the production demand, when flux is consisting of high magnesium powder and high calcium powder, burst temperature is optimum at 560 ℃. Suitable roasting temperature of high magnesia fluxed pellet is 1 240 ℃, suitable roasting interval was narrow at a- bout 20 ℃, and suitable amount of liquid phase for the pellet is about 5%.
