On December 4, the Hay Think team entered the SDJL Energy Technology Group. Inside the tall and spacious factory building, rows of high-precision machine tools are running at full capacity, and the workshop is producing high-precision wind power spindles in an orderly manner.
At the same time, SDJL invested 500 million yuan in the "Offshore Wind Turbine Spindle and Precision Drive Shaft Construction Project" production workshop is under rapid construction. Trial production on the 1st of the month, and the finishing workshop with an investment of 320 million yuan is under construction.” SDJL project manager said: “After the project is put into production, it will achieve an additional capacity of 64,000 tons of offshore wind power spindles, and the company`s sales revenue will exceed 2 billion. With a profit and tax of 800 million yuan, the global market share of wind power spindles has increased to 40%."
It is understood that in order to solve the technical bottleneck of the offshore wind power main shaft project, the company has carried out close cooperation with the Institute of Metal Research of the Chinese Academy of Sciences, Shandong Academy of Sciences, Shandong University and other units to overcome the organization and defects of the whole process of high-quality special steel blank preparation and hollow main shaft production. Technical difficulties such as genetic relationship have solved the bottleneck constraints of corrosion resistance and high strength in the manufacturing of offshore wind power spindles. Purchase the top domestic precision machining equipment such as CNC lathes and boring machines, as well as thermal processing equipment such as regenerative heating furnaces, presses, manipulators, etc. The product size accuracy can reach 4 microns, which can ensure trouble-free operation of offshore wind power spindles for more than 20 years.
As a key high-tech enterprise of the National Torch Program, SDJL's products are mainly exported to European and American countries [Nordex, RePower, Siemens Gamesa] and domestic wind power leading companies in China. The company's products account for 30% of the global market share. The company is also the world's most technologically advanced and largest An enterprise that produces wind power spindles. SDJL has a provincial-level technology center laboratory, and has won 2 provincial-level innovation honors, several municipal-level honors, 6 innovative patents, and more than 40 utility model patents.
SDJL's main products are wind power spindles ranging from 1MW to 6MW. It is a key high-tech enterprise of the National Torch Program that integrates wind turbine spindle R&D, production and sales. The company continues to expand its production scale and upgrade its process technology. It is one of the few wind power spindles in the wind power spindle industry that has the entire process of precision casting, forging, heat treatment, machining, and coating, as well as various large-scale forging manufacturers. It currently has an annual output of MW The production capacity of 8000-class wind power spindles and 120,000 tons of various large forgings. At present, the company's wind power spindles have reached 30% of the global wind power spindle market share, ranking first. It has the highest technical level, the highest degree of specialization, the highest market share, and the largest production scale in the global wind power spindle manufacturing field. The leading enterprise in wind power spindle manufacturing.
