摘要

高炉炼铁过程的生产率在很大程度上取决于炉渣的化学性质。大量的Al2O3等化合物的存在会使炉渣高度粘稠且难以挖掘。本研究第1部分的目的是对高氧化铝(Al2O3 > 15%)组成。对炉渣粘度、液相线温度、活化能等进行了严格审查,并提出了在所需条件下运行的相应解决方案。对炉渣的流动参数进行了检测,以了解直接影响出渣时间的熔融软化现象。还研究了在矿渣系统中添加某些添加剂,以提高矿渣的目标性能。本部分讨论了一系列矿渣成分及其优化技术,以深入了解该主题。

Optimization of high alumina slag practice in blast furnace ironmaking: an industrial approach (PART 1: fundamental aspects)
ABSTRACT The productivity of the blast furnace Ironmaking process is significantly dependent on the slag chemistry. The presence of compounds like Al2O3 in high quantities can make the hearth slag highly viscous and difficult to tap. The objective of part-1 of this study is to provide a comprehensive analysis of the role of high alumina (Al2O3 > 15%) compositions in the blast furnace slags. Slag viscosity, liquidus temperature, activation energy, etc., are critically reviewed with respective solutions to operate under the desired conditions. Flow parameters of the slag are examined to understand the melting-softening phenomena which directly affect the slag tap-to-tap time. The addition of certain additives to the slag system has also been studied with the aim to improve the target properties of the slag. A range of slag compositions and their optimization techniques are discussed in this part to provide greater insight into the topic.
