摘要
概述了我国炼铝工艺的现状以及铝冶炼方法的研究状况,并初步讨论与研究了煤烧结的一些基本规律。基于常规冶金存在的局限性以及真空冶金的优势,我们探索一种新炼铝的工艺,对低价化合物直接提取法作了一定的研究,低价化合物提取法主要包括了原料烧结实验、提取实验两大部分。本文着重研究了原料烧结实验部分中不同煤的配比,焦结温度对烧结团块性能的影响,得到最佳煤配比,焦结温度等重要的工艺条件和参数。它们是实验成功的关键。实验得到物料的最佳配比为10#煤∶5#煤∶16#煤∶工业A l2O3=3∶7∶10∶5,最佳烧结温度为520℃。
Reviews the current situation of aluminium smelting process in China, and discusses some basic rules of the sintering process with coal as fuel. Because of the limitation of conventional metallurgy and advantagas of vacuum-metallurgy, a new process technology was explored to extract directly the sub-valence compounds, which includes mainly two experiments, ie. , sintering of raw materials/coal and extracting. In the sintering experiment the material proportioning and how the sintering temperature affects the agglomeration were focused on. And such important parameters as optimal coal ratio and sintering temperature were obtained, ie. , the optimal coal ratio is 3g, 7g, 10g and 5g for #^10, #^ 5, #^16 coal and industrial Al2O3, respectively, and the optimal sintering temperature is 520℃.
