Aluminum Corporation of China Liancheng Branch finds a recipe for stabilizing electrolyte levels

According to the bulk non-ferrous net reprint: After more than four months of research, recently, Aluminum Corporation of China Liancheng branch 500 ampere series of electrolyte levels rebounded, the stability is getting better and better, and played an important role in the stable production and high yield electrolytic production.

It is reported that since the 500-kiloampere electrolysis series of China Aluminum Liancheng Branch has been started since 2012, due to the restrictions on anode quality and production guarantee conditions, and the immature technical route and energy imbalance, production has not been normal. Since September 2014, the entire series began to use outsourced high-quality anodes, and other factors that restrict production have also been better improved. The overall production situation has gradually improved, but the problem of unstable electrolytes and inability to maintain stability has not been resolved.

From March this year, the company's team focused on brainstorming, and gradually found out the causes of the low electrolyte levels, and took countermeasures: First, adjust the aluminum level, and gradually adjust the level of aluminum toward the lower limit; the second is in the slot The crushing screen is added to the loading box, and the shell blocks produced after changing the poles and the fragments and pastes grabbed by the grabs are crushed and sieved, and are added directly to the tank upper box through the guide sleeve to supplement Part of the electrolyte lost; the third is to add flotation material in the aluminum mouth. Through the implementation of the nine initiatives, the 500-kiloampere series of electrolytes has rebounded significantly and the stability is getting better and better.
