【摘要】 本文通过研究铝电解槽内铝液中铁含量的变化,得到槽启动初期铁含量的变化能够在一定程度上反映将来槽破损情况的结论;借鉴管理控制图的方法,研究了漏炉前铝液中铁含量的变化情况,发现当铁含量测量值连续7次在中心线(CL)上方波动、连续6次呈现上升趋势或者超出控制上限(UCL)时,电解槽可能出现漏炉事故。更多还原

【Abstract】 In this paper,change of the iron content within metal pad in aluminum reduction cell has been investigated to develop a method for possible early detection of cell linings failure.It is found that the change of the iron content in the early startup of the aluminum reduction cell can reflect pot lining failure in the future to some extent.Reference to the control chart,the iron content before leakage has also been studied and the results revealed three characters.When seven consecutive measurements of iron content above the center line(CL),or six consecutive measurements showing rise trend,or the measurements beyond the upper center line(UCL),the cell may come to break down.更多还原
