The first 3-generation electrolytic cell was successfully started

2019-11-05


At 11:00 am on October 31, more than 10 tons of red electrolyte liquid was slowly injected into 2052 no. The start of the tank marks that the third generation of the flag can electrolytic aluminum cell has entered the field trial stage, and also marks that the flag can electrolytic aluminum cell has taken the first step towards the ultra-long cell age.

Three generations of cell are calculated as the first generation cell type when the electrolytic cell is put into production. In order to pursue more excellent production indexes for generation by generation optimization, each generation cell type is integrated with the advanced technology and technology of the industry at that time. Compared with the second-generation tank, the third-generation tank is mainly optimized to build the furnace by means of pasting, changing the carbon blocks at the side to silicon nitridation bricks, and adopting the current advanced technology of replacing the double-steel rod with the cathode steel rod with variable section, which can effectively solve the problems of transverse stress release and side heat dissipation of the cathode, and reduce the horizontal current to a certain extent.

It is reported that the research and development of the third-generation tank began in early 2018. During the process, the company insisted on summarizing the reasons for the cathode damage of the first-generation tank and the weakness of the side of the second-generation tank from a large number of production data. In combination with the development status of the industry, the company organized several technical seminars and invited experts to discuss the specific implementation plan. After the joint work of the whole company, lasted more than a year, finally in 2052# slot to implement.

At present, there are 92 first-generation tanks and 203 second-generation tanks in qineng electric aluminum, the designed tank age is 1800 days, and the operation of the third-generation tank is expected to extend the average tank age to more than 2500 days. The overhaul cost of the electrolytic tank alone will save 16 million yuan every year, and the comprehensive benefit brought by the increase in production and the reduction of waste residue is more considerable. (From Alu)
