Harm of Prebaked Anode Oxid事要ation Slag and Crack fall-bloc樹湖k

What is the harm of prebaked 黑熱anode oxidation slag and cr跳人ack fall-block?

During the operation 到在of the electrolytic tank, carbon residue and debris are c知中ontinuously generated around the bott吧計om of the anode carbon 厭書block, which will not only increase t近間he carbon consumption, but also destroy機報 the normal technical c開土onditions of aluminum e明歌lectrolysis production by 文人suspending the carbon residue and debris in the electro他放lyte, which will seriousl計朋y endanger the normal prod制子uction of aluminum electrolysis 慢了and even lead to accidental tank stop.

The harm of prebaked anode o鐘醫xidation slag and crack fall-block are as follows:

(1) Changes in electrolyte conductivity, 東得thus affecting the normal operation開很 of aluminum electrolysis production;

(2) The electrolyte heats up, 照些creating a "hot tank". T是村he accumulation of carbon residue什件, the increase of el美票ectrolyte resistance, resu金務lting in higher tank v爸醫oltage and increase of heat income, gradually 鐘音lead to "hot tank", as a result of票信 which the current eff分大iciency decreases, electricity consum到件ption, carbon consumption an兵現d fluorine salt unit consumption;

(3) Retrieving carbon residue increased workload and aus林鄉ed economic loss. In order to keep the electrolyt就老ic tank running smoothly, the electr姐計olyte crust must be opened and carbon中照 residue and broken carbon an但和ode pieces must be continuousl理還y retrieved from the el就公ectrolyte at a high 動西temperature of 1000°C. The carbon residue retrie歌的ved out contains about 70% of分放 electrolytes, which 女道not only increases carbon and fluorine 內用salt consumption, but als微紙o increases heat los藍唱s and labor loss；

(4) Anode spikes and side leakage. The carbon residue 訊錯and anode debris wil山拿l gather together. Gathering a市請t the side will cause the curre東要nt to leak along the 公鄉anode - the gathered線不 carbon residue debr自公is to the side, makin女腦g it difficult to form the furnace gan樂光g; Gathering at the bottom o大問f the anode will cause t鐘件he anode spikes, which wil得說l seriously deteriorate the technical歌話 condition of the electrolytic tank and少空 resulting in a sick林熱 tank that is extremel白務y difficult to handle and e刀光ven causes leakage.
