為攻克氟化鋁單耗高這一難題，恒康鋁業(yè)多次組織召開(kāi)專題會(huì)議并成立攻關(guān)小組，從物料質(zhì)量及添加方法入手，尋找突破口。
電解車間添加氟化鋁通常采取兩種方式，一是人工向下料點(diǎn)投放氟化鋁到電解槽內(nèi)，二是定時(shí)向槽上部氟化鋁料箱內(nèi)添加，由工控機(jī)控制定時(shí)定量投放，恒康鋁業(yè)采用第二種添加方法。攻關(guān)小組發(fā)現(xiàn)因氟化鋁料箱與第二點(diǎn)打殼氣缸間距較近，大板梁內(nèi)空間小，槽上部添加氟化鋁過(guò)程中，放料人注意力不集中或?qū)Я鞑畚磳?duì)準(zhǔn)料箱口，溢出或撒落的氟化鋁流至槽上部大板梁內(nèi)后，無(wú)法清出，造成物料浪費(fèi)。根據(jù)這一情況，攻關(guān)小組通過(guò)驗(yàn)證討論，提出改造槽上部氟鹽料箱。
人工向自制料箱內(nèi)加氟化鋁時(shí)，料箱下鋪設(shè)彩條布便于回收，并改造料箱下閥門(mén)，將料箱與第二點(diǎn)打殼氣缸間隙用鋼板焊接，有效杜絕氟化鋁撒落大板梁內(nèi)，便于回收，減少物料浪費(fèi)。
此方案率先在電解一車間實(shí)施，截至目前，電解一車間一工段55臺(tái)電解槽已全部改造完畢，效果較為明顯。每點(diǎn)每次可節(jié)約0.25千克氟化鋁，平均每臺(tái)三天添加一次，每年一工段將節(jié)約1.15噸氟化鋁。其他工段槽上部氟鹽料箱改造也將逐步推進(jìn)。
