摘　　要：研究了新西兰海砂配比对承钢钒钛磁铁矿烧结过程及烧结矿冶金性能的影响。结果表明,适当增加海砂配比,垂直烧结速度、烧结利用系数均提高。烧结矿的粒度组成有所改善,机械强度和低温还原粉化性能变化不明显,荷重软化性能较好,矿相组成和结构比较复杂。综合考虑,海砂配比应控制在5%～10%。The influences of New Zealand sea sand proportioning ratio on vanadium-titanium-bearing magnetite sintering process and metallurgical properties of sinter were determined.The results show that the vertical sintering speed and utilizing coefficient all increase with increasing sea sand ratio.The grain size distribution of sinter is improved,and mechanical strength and low temperature reduction degradation property don＇t increase apparently.There are good softening Characteristics in experimental conditions.The composition and structure of sinter are complicated.The sea sand proportioning ratio in the Cheng Steel should be controlled 5%～10%.
