文章编号:1004-0609(2010)07-1260-07 镁基复合材料半固态压铸过程的数值模拟 胡 勇1,何柏林1,闫 洪2 (1. 华东交通大学 载运工具与装备教育部重点实验室,南昌 330013; 2.南昌大学 机电工程学院,南昌 330031) 摘 要:对镁基复合材料半固态充型凝固过程进行数值模拟,并进行半固态流变成形实验.结果表明,在液态充型过程中,压力变化非常紊乱;而在固态充型过程中,压力在推进方向上逐渐降低,这将产生有利于充型的背压.凝固过程的固相体积分数变化表明:在半固态充型条件下,整个铸件基本上是同时凝固,从而可有效地避免在液态充型时产生缩孔缩松.实验......

从钼酸铵溶液中除去砷的研究 杨亮,赵中伟,陈爱良,刘旭恒,霍广生 (中南大学 冶金科学与工程学院,湖南 长沙,410083) 摘要:镍钼矿常压空气氧化浸出液经N235萃取,氨水反萃后得到含砷的钼酸铵溶液.溶液中钼质量浓度达96.8 g/L,砷质量浓度为8.75 g/L,加入氯化镁使砷形成砷酸铵镁沉淀而除去.实验结果表明:当氯化镁用量为理论量1.2倍,反应温度为297 K,反应时间为30 min时,溶液中残留砷质量浓度为46.7 mg/L,钼入渣率为0.34%,残余Mg2+质量浓度为0.52 g/L;除砷后的钼酸铵溶液用724弱酸性阳离子树脂吸附除镁;当料液pH为9.2,流速为1 mL/m......
