【摘要】 将钢样电解后产生的大量阳极泥 ,用超声波震荡筛选、淘洗 ,去除直径小于 5 0 μm的夹杂。存在非磁性铁锈时 ,用H2 在 3 5 0～ 40 0℃将其还原 ,然后将磁选后磁性部分的夹杂物在显微镜下手工分离。用分级筛测定夹杂物大小 ,再对典型夹杂物进行电子探针定量成分分析。试验证明 ,阳极泥法在硅— (半 )镇静钢的应用中效果良好更多还原

【Abstract】 A large number of anode slime produced after electrolysis of steel sample is screened and washed and the inclusions of diameter less than 50μm are dislodged by ultrasonic wave concussion.It will be reduced by hydrogen at 350~400℃ for existing non magnetic scales,then the magnetic inclusions after magnetic separation are separated by hand with microscope.The sizes of inclusions are determined by grading screen.Then the quantitative analysis of composition is done to typical inclusions by electronic probe.The experiments have proved that the anode slime method used for silicon (semi)killed melted steel achieves a fine result.更多还原
