The Capacity Replacement Scheme for the Aluminum Electrolysis Construction Project of Yunnan Hongtai New-type Materials Co., Ltd. (Announcement No. 18 of 2019 by the Department of Industry and Information Technology of Yunnan Province) was publicly announced on December 26, 2019. The construction project planned to build six potlines, A, B, C, D, E, and F, to be constructed in phases and commissioned in sections. On January 25, 2021, two cells in Potline C (cell numbers 3344# and 3444#) passed the verification and acceptance conducted by experts organized by the provincial, prefectural, and county industry and information technology authorities, and were found to comply with the requirements of the Capacity Replacement Scheme for the Aluminum Electrolysis Construction Project of Yunnan Hongtai New-type Materials Co., Ltd. However, because they were located at the end of the second section and too close to the short-circuit busbar of the three-way corridor, the electromagnetic field stability was extremely poor. After the capacity replacement and verification in January 2021, they were not operated. The two cells in Potline D and the two cells in Potline C are all NEUI440kA electrolysis cells, each with a capacity of 2,405 mt, consistent with the construction content specified in the scheme. The Wenshan Prefecture Bureau of Industry and Information Technology, jointly with Yanshan County, conducted a verification and acceptance of the implementation of the capacity replacement scheme for the Aluminum Electrolysis Construction Project of Yunnan Hongtai New-type Materials Co., Ltd. (involving two units in the second section of Potline D). We hereby publicize the changes in the implementation of the capacity replacement scheme. The publicity period is from June 3 to June 7, 2026. During the publicity period, if there are any objections, please report them to the Wenshan Prefecture Bureau of Industry and Information Technology. Public supervision is welcomed.

Coal Tar Pitch Market Sees Stagnant Prices, Supply Increase Amid Downstream Hesitation

[SMM Aluminum Brief] In the coal tar pitch market, coal tar raw material prices were stagnant. Deep-processing operating rates rose slightly, leading to a modest increase in supply. Downstream anode enterprises purchased on a just-in-time basis and pushed for lower prices while adopting a wait-and-see stance, intensifying the supply-demand tug-of-war. Next week, the market is expected to continue its weak consolidation: raw material prices will see no significant fluctuations, downstream players are unlikely to restock in a concentrated manner, and prices lack upward momentum, with a high probability of a slight decline.
