Abstract Blast furnace slag and steelmaking slag, as the main accessory products of iron steel smelting, are piled up in large quantities due to their huge output, high treatment difficulty low comprehensive utilization rate, which has a serious impact on land environment. In order improve basicity blast was added existing for quenching tempering. The influence chemical composition phase precipitation mixed analyzed. research process, morphology Baotou Steel were analyzed using FactSage7.1...
In order to transform the crystalline form of Ca2SiO4 (C2S) in phosphorus-containing slag from monoclinic β-polycrystalline square γ-polycrystalline, a volume expansion about 11% was generated, which caused undergo self-powdering. The CaO-SiO2-Al2O3-MgO-MnO-P2O5-FeO system analyzed using FactSage7.1 thermodynamic software, and effects different P2O5, FeO basicity on mineral phase composition were range 1300~1700 °C. It shown that all have an effect phases. When mass fraction P2O5 lower than...
This study investigates the pattern of influence blast furnace slag tempering on composition and structure steel slag. The chemical composition, equilibrium phase microscopic morphological characteristics elemental regions modified by high temperature reconstruction were analyzed using X-ray diffractometer (XRD), FactSage7.1 thermodynamic analysis software, mineral microscopy field emission scanning electron microscopy. results show that blending can promote generation a low melting point in...
In order to investigate the influence of SiC on composition and structure mixed slag (blast-furnace slag: steel = 1:9), chemical composition, equilibrium-phase microscopic morphological characteristics elemental distribution in region SiC-reagent-tempered samples were analyzed by X-ray diffractometer (XRD), FactSage7.1 thermodynamic analysis software, scanning electron microscope, energy spectrum analyzer. It was found that main physical phases tempered magnesia–silica–calcite (Ca3Mg(SiO4)2,...
In order to reduce the sintering allocation scheme and lower cost of allocation, two semi-lignite ores with similar properties large price differences were selected for blending achieve purpose complementary advantages. The sintered ore specimens studied by using FactSage7.1, an infrared furnace, regression analysis. results show that OA OB iron powders their mixed have a good linear fitting effect inverse relationship between bond phase strength SiO2 content; has positive liquid fluidity...
