ã€China Aluminum Industry Network】 1. Production process of electrolytic aluminum: Second, the production cost of electrolytic aluminum The production cost of electrolytic aluminum is mainly divided into: Alumina, electricity, auxiliary materials (fluorinated salt and anode carbon, etc.), labor and depreciation are three parts. Among them, alumina, fluoride salts, and carbon materials are the raw materials for electrolytic aluminum. An average of one ton of electrolytic aluminum consumes 1.95 tons of alumina and 25 Kg of fluoride salts. 1. Alumina cost Generally speaking, every ton of electrolytic aluminum needs to consume 2 tons of alumina, but most manufacturers currently produce 1 ton of electrolytic aluminum and consume about 1.93 to 1.98 tons of alumina, although this proportion is There will be a downward trend in the efforts of various manufacturers, but the decline will be small, and we understand it as a constant. At present, the market price of alumina is basically maintained at 2,200 yuan/ton to 2,300 yuan/ton, and we maintain a constant price of 2,200 yuan/ton according to the basic stable market price. We take a constant of 1.95 tons for each ton of electrolytic aluminum production. It can be calculated that the cost of alumina consumed by one ton of electrolytic aluminum is 4290 yuan. 2. Cost of Electricity Due to the large output of electrolytic aluminum in Henan, the electricity price in Henan is calculated as the electricity price in Henan, which is about 0.442 yuan/kwh. According to the national policy, starting from July 1, the national electricity price is generally raised by 0.025 yuan/kwh, from which the current average electricity price is estimated to be 0.467 yuan/kwh. The electrolytic aluminum industry consumes a lot of electricity. Due to the difference in the level of production technology and equipment, the electricity consumed by each production enterprise for producing one ton of electrolytic aluminum is quite different. At present, it is generally between 14000kwh and 16000kwh, according to the country's consumption in 2008. Electricity standards, per-ton electrolytic aluminum production of electrolytic aluminum links AC power consumption is 14400kwh, before the price adjustment and electricity price adjustments per ton of electrolytic aluminum electricity costs were about 6365 yuan and 6,725 yuan, the increase was about 360 yuan. 3. Auxiliary materials (1) Anode carbon costs Currently, the world's electrolytic cells are divided into self-baking cells and pre-baked cells. Since the anode carbon is first calcined and there are more processes, the cost of the anode carbon block is relatively high. At present, self-roasting tanks have been gradually eliminated by the country due to serious pollution. Therefore, the pre-baked cells, which are more commonly used now, are accounted for. The market price of one ton of anode carbon is about 2,000 yuan, and each ton of electrolytic aluminum pre-baking trough consumes 0.6 tons of carbon. Based on this, one ton of electrolytic aluminum consumes 1,200 yuan of anode carbon. (2) Fluoride salt At present, the market price of fluoride salt is about 2,600 yuan/ton, which generally consumes 25KG per ton of electrolytic aluminum. According to the accounting, about 1 ton of electrolytic aluminum consumes 65 yuan of fluoride. In summary, the average social raw material cost per domestic ton of electrolytic aluminum consumed is 4290 (alumina) + 6725 (electricity price) + 1200 (anode carbon) + 65 (fluorinated salt) = 12280 yuan. This is only a relatively basic direct material cost in the manufacturing cost, and a company must pay the salaries, management fees, financial expenses and sales expenses of the company staff, amortize the depreciation expense of the machine factory, bank loan interest, and must be paid for simple social reproduction. Taxes, etc., should all be included in the company's production costs. According to statistics from CBI, the current cost of domestic enterprises accounts for about 13% of the total cost of electrolytic aluminum production. According to the recent electrolytic aluminum market price of 12,280 yuan/ton, the cost is about 2029 yuan, then a ton. The total cost of electrolytic aluminum is around 17,637 yuan.
