本文通过加入添加剂改变难选锡中矿成分,采用荷重变形法测定和研究了不同成分对该矿球团的软化性能的影响,从中获得了某些规律性认识,可供生产单位参考。试验结果初步表明,加入适量矿物添加剂,不仅能改善物料的高温软化性能,而且在适宜的焙烧条件下,还取得了满意的氯化挥发效果和氧化固结质量。 In this paper, by adding additives to change the composition of refractory tin ore, the load deformation method was used to measure and study the influence of different components on the softening performance of the pellets. Some regularity was obtained from which the reference can be made for production units. The preliminary test results show that adding appropriate amount of mineral additives can not only improve the high temperature softening performance of the material, but also achieve satisfactory chlorination volatility and oxidation and consolidation quality under suitable roasting conditions.
