December 26, 2010, Baosteel produced by the first domestic nuclear power steam generator tube with 690U delivery ceremony in Yixing City, Jiangsu Province Special Steel Tube Co., Ltd. held Bao Yin.
The batch will be delivered to Dongfang Electric (Guangzhou) Heavy Machinery Co., Ltd., applied to ethnic minority areas in China's first nuclear power project - Fangchenggang City, Guangxi Zhuang Autonomous Region Unit 1 nuclear power. glue stick This is also the first use of nuclear power projects in China-made nuclear power steam generator tube with the 690U, get rid of the long-standing dependence on foreign similar products, to meet the major equipment of the key materials in the field of nuclear power to realize the localization of the urgent need for long-term protection of our nuclear facilities and the effective operation of the National Nuclear Security is of great significance.
Nuclear steam generator tube with 690U million-kilowatt nuclear power plant is to be the key to the special materials used.glue gun The manufacturing process requires extremely demanding, manufacturing process is extremely complex, with a number of core technologies and innovation, on behalf of the international nuclear power today manufactured with top level management. Because of its high technical content, before the world, only France, Japan, Sweden, the three countries can produce such products.
To develop nuclear power in accordance with the overall national strategic planning and the demand for clean energy, Baoshan Iron and Steel Co., Ltd. and Jiangsu Yinhuan Precision Steel Tube Co., Ltd., China Guangdong Nuclear Power Group, a joint venture company, formed by the Bao Steel Holdings Ltd. Bank of special steel and the construction of the first domestic nuclear power steam generator tube with 690U professional production line. The project was groundbreaking in June 2007, August 2008 officially started construction. December 2009, Baosteel and 690U-tube extrusion production line built and put into production. April 2010 and June, and 690 were completed and finished extruded tubes U-tube analog parts, pre-approved the trial, and through the National Nuclear Security Administration Organization experts. June 12 the same year, Baosteel awarded by the National Nuclear Security Administration, the nuclear level, extruded tubes manufacturing license; August 4, issued by the National Nuclear Security Administration, the nuclear level, U-shaped tube products manufacturing license.
R & D process, Baosteel 690U consistent system-tube manufacturing technology R & D team has overcome a vacuum smelting, remelting, forging, hot extrusion and pipe forming process and a series of technical problems to straighten out the finished product from the smelting control the entire process of the process, the formation of the independent design, independent building, the whole process of self-made intellectual property rights. Given the special nature of the nuclear power industry, Baosteel has established a perfect quality assurance system of nuclear and innovative management to ensure product quality foolproof. Each team finished tube off the assembly line are marked with a "birth certificate", its manufacturing process, use whereabouts and other information are available on the database query to. In addition, Baosteel also strengthened the meticulous management, requiring all employees at the production site must be wearing a special piece overalls, wearing white gloves, to be in direct contact with the product are covered with a soft outer surface of the equipment, ensure the greatest degree surface quality.
Dongfang Electric (Guangzhou) Heavy Machinery Ltd., based on the 690U-tube manufacturing, item control, quality assurance and quality control ability of the assessment, has been recognized as a qualified supplier Baosteel and Baosteel in accordance with the existing mature technology collaboration go all out to produce high-quality completion of Unit 1 nuclear power Fangchenggang 150 tons of products with all the delivery mission.
