In order to resolutely win the tough battle of "stop slipping, reduce losses and increase profits", all units of the company have strengthened management, deeply tapped the potential of expenses, and promoted extreme cost reduction to achieve substantial results.
Tiancheng Aluminum Co., Ltd.
In order to reduce the unit consumption of aluminum-titanium-boron wire in the rolling mill, the company calculates the consumption of titanium wire according to the type of alloy, and makes the control method of titanium wire index differentiation more scientific and reasonable by taking measures such as setting goals, on-site investigation, cause analysis, and method improvement. , the overall consumption of titanium wire showed a downward trend. After a year of hard work, the unit consumption of titanium wire has been reduced from 2.0kg/t in 2021 to 1.87kg/t in October 2022, and the annual direct purchase cost has dropped by about 1.31 million.
Jiayuguan Electrolysis No. 4 Operation Area
Since October, the operation area has started from strengthening the process control of the process link, and strictly controlled the process operations such as new electrode installation, plugging, and conduction, effectively reducing the pressure drop at the bottom of the furnace by 12mv. Strengthen the operation and control of retightening small box fixtures after lifting the busbar, reduce the retest clamping pressure, clamp pressure drop by 1.8mv, and the qualification rate of clamp pressure drop increased to 96.8%. Take reasonable use of the high residual electrode generated by the start-up of the cell, increase the sealing degree of the electrolytic cell, extend the service life of some cell anodes to 33.5 days, and reasonably adjust the amount of fluoride salt addition to reduce the unit consumption of the anode by 1.1kg/t. The unit consumption cost of anode is reduced by 12.8 yuan/ton, the unit consumption of aluminum fluoride is reduced by 0.5kg/t, and the unit consumption cost of aluminum fluoride is reduced by 5 yuan/ton.
