三元系相图直角坐标表示法及其在CaO-SiO2-Al2O3系中的应用 黄柱成1,李光辉1,朱忠平1,姜涛1 (1.中南大学资源加工与生物工程学院,湖南,长沙,410083) 摘要:采用直角坐标系描述三元系相图的方法,建立了直角坐标系下物质浓度的表示法.应用该方法,将相图中物相成分转换成点的坐标,精确计算各物相平衡结晶组成,使得物相组成的确定更为准确方便.将该方法应用于CaO-SiO2-Al2O3炉渣三元系相图中,使得高炉渣矿物组成的确定由估算变为精确计算,为炉渣矿物组成的分析及高炉操作的改善提供了一种快速有效的方法. 关键词:三元相图; 直角坐标; 炼铁; 炉渣; [全文内容正在添......
powders with particle size range of 200-450 μm bore the best magnetic properties of Br of 1.24 T and Hci of 860.4 k A/m. Compared with magnetic properties of the waste magnet, the powders retained 93.9......
