摘要

为了了解高Al2O3含量的高炉炉渣的性能，采用差示扫描量热法(DSC)研究了w(MgO)/w(Al2O3)、w(CaO)/w(SiO2)和w(Al2O3)对高Al2O3含量高炉炉渣熔炼性能(熔炼特征温度和熔炼热)的影响。实验结果表明，随着w(MgO)/w(Al2O3)、w(CaO)/w(SiO2)和w(Al2O3)的增加，几乎所有炉渣的熔融终温度(Tend)都没有明显变化，而w(CaO)/w(SiO2)和w(Al2O3)会使炉渣的Tend升高。当(w(MgO)/w(Al2O3)、R和w(Al2O3)较高时，渣的熔化起始温度(Tonset)随各变量的增加而升高。当w(CaO)/w(SiO2)较低时，炉渣的吨位随w(Al2O3)的增加而减小。w(MgO)/w(Al2O3)、w(CaO)/w(SiO2)、w(Al2O3)均在本研究范围内，这些因素均导致熔渣热增大。

The melting performance of high alumina blast furnace slags

With a view to understanding the performance of the blast furnace slag with high Al2O3 content, the effects of w(MgO)/w(Al2O3), w(CaO)/w(SiO2), and w(Al2O3) on the melting performance (melting characteristic temperature and melting heat) of the blast furnace slag with high Al2O3 content were investigated by the differential scanning calorimeter (DSC) method. Experimental results indicate that melting end temperature (Tend) for almost all the slags has no obvious change with the increase of w(MgO)/w(Al2O3), w(CaO)/w(SiO2) and w(Al2O3) of the slag will raise Tend of the slag. When (w(MgO)/w(Al2O3), R, and w(Al2O3) are high, the melting onset temperature (Tonset) of the slag increases with the increase of any variables. When w(CaO)/w(SiO2) is low, Tonset of the slag decreases with the increase of w(Al2O3). w(MgO)/w(Al2O3), w(CaO)/w(SiO2), and w(Al2O3) within the scope of this study and all these factors lead to the increase of the slag melting heat.

期刊介绍： University of Belgrade, Technical Faculty in Bor, has been publishing the journal called Journal of Mining and Metallurgy since 1965 and in 1997 it was divided in two independent journals dealing with mining and metallurgy separately. Since 2009 Journal of Mining and Metallurgy, Section B: Metallurgy has been accepted in Science Citation Index Expanded. Journal of Mining and Metallurgy, Section B: Metallurgy presents an international medium for the publication of contributions on original research which reflect the new progresses in theory and practice of metallurgy. The Journal covers the latest research in all aspects of metallurgy including hydrometallurgy, pyrometallurgy, electrometallurgy, transport phenomena, process control, solidification, mechanical working, solid state reactions, materials processing, surface treatment and relationships among processing, structure, and properties of materials.
