Recently, there have been huge power shortages in Zhejiang, the Pearl River Delta and Central China, which have begun to affect the raw materials and non-ferrous metals industries such as ferroalloys and aluminum. "First Financial Daily" reporter yesterday consulted a number of aluminum companies and ferroalloy enterprises found that enterprises have been affected by power cuts, facing the problem of insufficient operating rates. It is understood that some of the power-restricting phenomena have appeared in Henan and Hunan areas where aluminum production capacity is relatively concentrated. For example, some aluminum processing enterprises in Henan Province have received notifications of local government power cuts. However, for electrolytic aluminum enterprises with large power consumption, At present, there is no reduction in production due to a shortage of power supply, but many companies believe that the power supply will be more tight in the future. According to Zhang Jian, an analyst at Shanghai Nonferrous Metals, the current power gap in Hunan Province is as high as 4 million kilowatts, equivalent to nearly 30% of electricity demand. However, the largest electrolytic aluminum company in the region said that the company mainly relies on its own power plant for power supply. Although the power generation cost is high (the local 5,000-kilometer thermal coal purchase price is about 800 yuan/ton), it has not affected normal production. Liu Zhenhua, head of the production equipment department of Chinalco Henan Aluminum Co., Ltd., told the reporter that the company has not received a notice of power cuts, and the production is still in progress. However, based on the experience of previous years and the state of this nationwide power shortage this year, it is expected There will be some impact in the future, and the three months of July, August and September are expected to be the most serious. Liu Zhenhua said that when there is a peak in summer electricity consumption in the past year, the local government will take some large-scale high-energy-consuming enterprises to take measures to reduce the voltage by taking measures of reducing production several days a week. Due to some changes in asset restructuring and leasehold joint ventures, Henan Aluminum has only two branches in production, and has not been producing at full capacity. If power is cut, some production structure adjustments will be made to deal with them, such as stopping unused. The equipment, originally operated three shifts a day, now only uses two and the wrong peak production. Liu Zhenhua is more worried about the shortage of raw materials due to power cuts. At present, many electrolytic aluminum production enterprises have their own power plants, but they want to purchase raw materials such as double-column ingots, cast-rolled coils, etc. Once the raw material suppliers cut production due to power cuts, aluminum companies are bound to be affected. In Hunan, where the power gap is huge, some ferroalloy enterprises that consume large amounts of electricity have also been affected. According to the reporter's understanding, Minmetals (Hunan) Ferroalloy Co., Ltd. has been affected by the power shortage for nearly 20 days. At present, the power supply is unstable, resulting in insufficient operating rate. The company has not yet received notice when it can resume normal power supply. Li Guilong, general manager of Hunan Haoye, told reporters that in order to cope with the summer power supply, the company is currently undergoing equipment maintenance and power supply is relatively tight, so the smelter has begun to carry out peak production. Li Guilong told reporters that according to previous years' experience, once the summer begins to limit electricity, the most serious time is August and September. Enterprises will reduce production by about 20%, and the losses will be relatively large. The proportion of hydropower in Hunan is relatively large. If it encounters a dry season, it is possible to stop production. He also revealed that at present, the proportion of processing enterprises in some counties and districts that have reduced production and stopped production has reached more than 10%.
A plate flange is a flat, circular disk that is welded onto the end of a steel pipe and allows it to be bolted to another pipe. Typically used in fuel and water pipelines, the two flange plates will be bolted together with a gasket in between them. The flange plate will have bolt holes all around the perimeter and will be used to create junctions, tees and joints.
