锰精矿烧结工艺参数探讨

Discussion on Sintering Technological Parameter of Manganese Ore

锰精矿具有质地松软、粘结、内含水分大的物理特性,属于难烧物料。其主要的烧结指标为垂直燃烧速度、烧成率和烧结矿转鼓强度。本次试验通过烧结杯试验,研究锰精矿烧结指标,结果得出,锰精矿烧结焦粉配比要求很高;碱度不易太高;同时,在锰精矿中加入普通精粉,可以改善锰烧结矿质量。

Manganese ore its the character on soft, binding, contains more moisture, and it is different to sinter. The main sinter index is the vertical burning speed, sintering rate and drum strenghth. This test has studied the sinter index of manganese ore trough sintering cup, which finds that the coke powder rate of manganese ore sinter is higher; CaO/SiO2 should not be too high;at the same time, put some ordinary ore powder into the manganese ore, the sinter index can get better.
