中文摘要:
      高炉渣的化学成分对其微观结构具有重要影响,改变高炉渣的化学成分,高炉渣的微观结构也发生改变。本文综述了碱度、MgO、Al2O3和MgO/Al2O3等化学成分对高炉渣微观结构的影响,高炉渣主要为硅氧四面体相互连接成的网络结构,Ca2+、Na+等离子进入到炉渣网络结构中破坏了硅酸盐网络结构,促使硅酸盐中简单结构单元增多;Al3+、Ti4+和B3+等离子在不同环境中对高炉渣微观结构起到不同作用,既可以使炉渣网络结构复杂化,也可以使炉渣网络结构转变为较小的结构单元。并指出了关于化学成分对中钛渣微观结构影响是中钛渣的研究重点。
英文摘要:
      The chemical composition of blast furnace slag has important effects on the microstructure, the change of the chemical composition of blast furnace slag,and blast furnace slag microstructure change too.Alkalinity, Al2O3 and MgO style was reviewed in this paper to explore the impact of the microstructure of the chemical composition of blast furnace slag, blast furnace slag are formed the reticular structure through the silicon oxygen tetrahedron connects; Ca2+, Na+ plasma into the network structure of slag destroyed the silicate network structure, and simple in driving silicate structure increase; Al3+, Ti4+ and B3+ plasma in different environments will exert different effects on blast furnace slag microstructure, which can complicate the slag network structure, and also make slag network structure into smaller structural unit. And the research points out that the chemical composition in the impact on the microstructure of titanium slag is the research emphasis of titanium slag.
