Key.In production run, the composition of anode-covered material is electrolyte granular and the oxidation of different grain size size to existing aluminium cell
The mixed material of alumina particles, mulch mainly plays a part of to be incubated and prevents anode surface from aoxidizing, mulch mainly by overhead traveling crane and
Manually it is added.
In electrolysis production link now, change poles almost turn into every electrolytic cell daily necessary to operational sequence, and from
Change poles prepares to start, and to the addition for completing mulch, takes about 30min.During change poles, there are such some steps, such as：
Preparation change it is old it is extremely preceding the loosenings mulch of anode surface is shoveled out, overhead traveling crane loosens hardened coating, taking-up anode, extremely gone up newly
Addition mulch etc., produces substantial amounts of dust in these steps, deteriorate operating environment.
Meanwhile, electrolytic cell production run requires fine-grained management further, in the addition step of anode-covered material, each factory rules and regulations
The model component proportion of mulch, Particle size requirements, cladding thickness etc..However, more artificial participations make practical implementation difficult
To accomplish the monitoring of quantification of targets and implement, each workshop section, the presentation attributes of each area's electrolytic cell are difficult to standardize.
