The Harm of Prebaked Anode Oxidation 區媽Slag and Crack Fall-Block

What is the harm of prebaked anode o海鐵xidation slag and crack fal海頻l-block?

During the operation of the 唱樂electrolytic cell, carbon resi紅火due and fragments are continuously p議林roduced around the bot喝用tom of the anode carbon block.討裡 This will not only in湖快crease the carbon cons理中umption, but also suspended in the 開水electrolyte carbon sl是線ag fragments will undermine the norm會老al production of electr男門olytic aluminum tech麗行nical conditions, ser書土iously endanger the normal p為湖roduction of aluminum electrolysis, a頻報nd even lead to accident stop 唱中slot.

The harm of prebaked oxidation s理公lag and crack fall-block mainly 電山includes the following aspects :說為

(1)Changes in the conductivi身腦ty of the electrolyt器草e, thus affecting the normal operation問樂 of aluminum electrolysis prod河森uction；

(2)The electrolyte heats up水匠, creating a "hot tank". T司大he accumulation of carb視麗on residue, the increase of 信裡electrolyte resistanc資如e, the increase of tank voltage, the街可 increase of heat income, gradually le動高ad to "hot tank", resulting in a decre刀廠ase of current efficienc鐵答y, power consumption, carbon c紅城onsumption and fluorine salt討讀 unit consumption.

(3) Increased workload 拍吧and economic loss from salvagin雜和g carbon residue. In o答東rder to keep the electrolyzer running s他器moothly, it is necessary t吃們o open the electrolyte crust船刀 and continuously salvage the carbon路跳 residue and carbon anode pie請畫ces from the electrol資愛yte at a high temperature of 1000開劇°C. The salvaged carbon residue contain的很s about 70% electrolyte, which 多廠not only increases carbon and fluorin又美e salt consumption, but花得 also increases heat 窗金and labor losses.

(4)  Bags on anode and side leaka北愛ge. The carbon residue and坐美 the anode pieces will gather體習 together, and when they gather at子通 the side, the current will l這和eak along the anode-collected聽物 residue pieces to t錢畫he side, making it difficult to for又麗m the furnace hearth. When the 多生anode is gathered at the bottom,對如 the anode will grow bags, 木這which will seriously wor雜子sen the technical condition of th算看e electrolytic cell, create 山器a very difficult to diseas雨吃ed cell, and even cause slot le空內akage.
