shougang’s oriented electrical steel applied in baihetan hydropower station -j9九游会真人游戏第一

at present, the dam of baihetan hydropower station, the world’s largest hydropower project under construction, with a total installed capacity of 16 million kw, was filled to the top on may 31st, laying a solid foundation for the first batch of units to be put into production before july this year. the relevant data shows that shougang zhixin electromagnetic has supplied 3,000 tons of high-quality high-magnetic-induction oriented electrical steel. the 25 sets of 500 kv transformers, adopting shougang’s oriented electrical steel as their main material, account for 50% of the main transformers on both sides of baihetan hydropower station. shougang’s oriented electrical steel is helping the “white crane” to take off and adding splendor to “advanced machinery” once again.

baihetan hydropower station is the world’s second largest in installed capacity and largest in construction scale. it is an important part of the power supply for the national hydropower development strategy and “west-east power transmission”, and a major supporting and landmark project for the “13th five-year plan”. upon full operation, the station will be able to generate enough electricity in one day to supply 500,000 people with electricity for a year, and its annual generating capacity will be able to reach 62.443 billion kw/hour. consequently, it can save about 19.68 million tons of standard coal per year, and reduce carbon dioxide emissions by about 51.6 million tons. along with wudongde, xiluodu and xiangjiaba cascade power stations on jinsha river and the three gorges and gezhouba hydropower stations, it will form the world’s largest clean energy corridor, which will improve china’s energy structure, meet the increasing demand for electricity, realize energy conservation and emission reduction, and promote china’s low-carbon social and economic development.

since it first produced oriented electrical steel, shougang has aimed at the requirements of the national strategies and engineering. the steel has been applied in batches of ultra-uhv transformers at 500 kv and above, and won the high recognition of the industry for its product quality, performance stability, service capability and delivery assurance.

since 2017, in order to advance the baihetan hydropower station project, shougang visited the three gorges corporation and transformer factory many times, and conducted in-depth exchanges on the electromagnetic design, processing and manufacturing period of the transformers. according to the specific requirements of the transformer factory for the electromagnetic performance, noise index and dimensional accuracy of oriented electrical steel, shougang transformed various technical standards into internal control points, and began to supply the baihetan project’s transformer factory with steel in july 2019.

shougang has always insisted on independent innovation driven by technological progress, and continuously improved the quality of its oriented electrical steel products. adhering to the integrated operation mechanism of production, marketing and research, and the consistent quality management system, shougang has achieved breakthroughs in high-end product r&d, whole-process manufacturing, process optimization, user application technology, etc. the comprehensive technical performance of shougang’s high-magnetic-induction oriented electrical steel products has reached the international advanced level for similar products, among which its noise index and coating adhesion index have reached the international leading level. the two energy-saving and low-noise products have achieved their global launch, and the ultra-thin oriented electrical steel has held the highest market share in china for three consecutive years, ranking first in the world.

shougang’s high-magnetic-induction oriented electrical steel products are widely used in transformers of 500 kv and above, integrated in such national strategic engineering construction as wudongde hydropower station, changlongshan hydropower station, state grid xilin gol league-shandong, huainan-shanghai and zhangbei-xiong’an uhv transmission, hong kong-zhuhai-macao bridge, beijing winter olympics venues, guangdong taipingling nuclear power plant and so on. shougang’s products have been exported to 29 countries and regions including japan, south korea and italy, and successfully applied in angola, laos, thailand and other “belt and road” national power stations and power grid projects. shougang has climbed the peak of product r&d and technological innovation, and truly controlled the key core technology of “advanced machinery” in its hands, thereby contributing its wisdom, strength and responsibility to china’s security, strategy and economy, and the people’s livelihood.
