June 29, Wu Dongde Hydro Power plant launched its first generators, a brand new 10 million KW class hydro power plant of the country, in which HBIS delivered over 160,000tons of premium steel，enhancing the domestication of hydro power equipment steel.
Dong Wude power plant owns a capacity of 10.2million KWs and it will the fourth in China and 7th largest hydro power plant in the world. In the early stage of the project, the contractor, Three Gorges Dam Group carried out thorough studies together with project designers, equipment manufacturers and Chinese Iron & Steel Association experts. The team adopted 780Mpa class high strength steel, back then, the world’s highest strength hydro power steel in actual project applications. HBIS, the world’s largest steel manufacturer pursues a high end path and developes hydro power steel materials for key domestic projects. The designated type SX780CF special hydro power steel owns excellent welding, mechanical and low temperature anti-impact capabilities.
The rotor of the generator is the largest rotor lifted by a crane in the world. The core of this super structure is the frame supporting rotor. All the steel matierals supporting the center rotor and fan-shape structures were HBIS special steel. With its advanced procedures, HBIS developed its new Oxide steel making technologies and guaranteed welding quality and capability. The 800MPa series high strength steel is well weldable now.
Wu dongde project adopts a concrete dome dam design and it is the world’s thinest 300m tall dome dam, raising strict standards to supporting materials. HBIS studied the special geographic conditions of the project and applied microalloy strengthening technologies. The teams tightly controlled the specifications of materials and ensured the yeilding strength and tenacity, making them the best in the industry.
Wu dongde is a key grid in the West-East Power Transmission Project of the country. After completion, Dong Wude will generate 38.91billion KWH each year. In the Dong Wude pilot DC Guangdong & Guangxi transmission project, HBIS provided over 110,000tons of angles to build cable towers. To meet new national steel standards of cable towers, HBIS develops 28#、30# large dimension angles that top in the country. HBIS becomes the exclusive supplier of angles to State Grid Company.
Performing the contract, HBIS launched its key project oriented HBIS model and its key client managers sent “microteams”to provide services to each specific demand and guaranteed the project construction.
