本溪钢铁公司炼铁厂团烧车间使用贫精矿粉(含Fe～60％,SiO_2～14％)来制造高碱度自熔性贫团矿。在高温下熔化现象甚为严重。 经实验室中研究的初步结果,认为烧成高碱度的贫团矿,其温度范围变化很窄,因此首先要求严格控制团矿的焙烧温度制度,同时分析了影响烧成自熔性贫团矿的一些因素。工业试验得出的初步结果,基本上是和实验室所得的是符合的。 本文的后面作了烧成自熔性贫团矿的初步理论分析,供作讨论。
Benxi Iron and Steel Company Iron Works Group burning workshop using lean ore powder (containing Fe ~ 60%, SiO2 ~ 14%) to create high-basicity self-melting lean ore. Melting at high temperatures is very serious. According to the preliminary results of laboratory research, it is considered that the temperature range of the calcined high-alkalinity lean mines is very narrow. Therefore, it is necessary to strictly control the calcination temperature of the mines, and at the same time, Some factors of mine. The preliminary results from industrial tests are basically consistent with those obtained from laboratories. The back of this paper made a preliminary theoretical analysis of self-molten lean mines for discussion.
