You must have seen wind turbines with a height of more than 60 meters. What can connect all these wind towers together to form a towering wind tower and keep it standing is a very critical component, the wind tower flange. 60% of the country's wind tower flanges are from Dingxiang.

The blazing flame in the forging heating furnace, the billet forging and forming on the oil press, the reaming on the ring grinding machine, and the finishing of the CNC vertical lathe... Pieces of wind power flanges are continuously manufactured in the "thousands of hammers" and are waiting for delivery after inspection and packaging. In the past few days, in the workshop of Shanxi Tianbao Group Co., Ltd., workers have been busy nervously processing a batch of orders.

"in the past, we all forged flanges by hand, and it took more than four hours for more than a dozen people to forge a flange, but now the automatic production equipment we use only takes three or four people to produce one in five minutes. The efficiency is at least 50 times higher than in the past." Fan Jingyun, vice president of production of Shanxi Tianbao Group, tells the difference between forged flanges before and now.

"In the past ten years, the flange manufacturing level of our company and even the whole county of Dingxiang County has undergone a radical change. In the layman's view, the change from the traditional clamp hammer to the hydraulic press is actually the iteration of technology and the progress of ideas." When it comes to Dingxiang's flange manufacturing level, Yan Zhilong, the technical "big coffee" of Shanxi Tianbao Group, the leading enterprise of Dingxiang flange forging, has the most say. Under the unremitting research of him and a group of experts, Shanxi Tianbao Group has stepped out of Dingxiang and become the leader of domestic flange manufacturing industry.

Shanxi Tianbao Group is one of the leading enterprises specializing in the production of wind power flanges, pressure vessel flanges and large forgings, with total assets of 0.64 billion yuan. Its wind power products are exported to India, Brazil, Mexico, Spain, Germany, Australia, Argentina and other countries and regions, becoming the first choice of more than 40 enterprises, such as major power companies and wind turbine manufacturers.

The reporter walked into the "digital wing" of Shanxi tianbao group, and the online data monitoring screen of the intelligent manufacturing MES system displayed the processing progress of each product in real time. Digital application scenarios have gradually covered all aspects of enterprise research and development, production, warehousing, finance, and management.

In recent years, Shanxi Tianbao Group has promoted the improvement of its core competitiveness with scientific and technological innovation, established long-term strategic cooperative relations with five major national power companies, ten major wind turbine manufacturers, more than 30 large domestic and foreign related enterprises and Sinopec related enterprises, and jointly tackled new technologies. set up a scientific research team and increase investment in research and development, 72 patented technologies provide strong support for the promotion of core competitiveness and market development; with an investment of 0.223 billion yuan to build an intelligent manufacturing expansion project for wind power generation ring forgings based on 5G cloud platform, with 10,000 t oil press, 10M ring grinding machine and other high-end precision equipment, the manufacturing level of products and the construction level of digital production lines have been further improved, the quality management system has been further improved, and the intelligent equipment and production system have been realized.

"We have also purchased domestic advanced forging, machining, heat treatment, automatic control, automatic detection and other equipment. By adopting modern high-tech of 5G cloud platform, we have built an intelligent manufacturing project with an annual output of 60000 tons of wind power ring forgings, with an annual production capacity of more than 100000 tons, reaching the leading level in China." Fan Jingyun said proudly, "We have continuously strengthened technological innovation and obtained 18 invention patents and 59 utility model patents. The provincial technology center we established has also been rated as a public service demonstration platform for small and medium-sized enterprises in Shanxi Province."

Shanxi Tianbao Group also actively participated in the formulation of corporate standards and norms to promote the transformation and upgrading of the flange manufacturing industry. In 2019, the group took the lead in the preparation of the group standard "Wind Turbine Tower Flange Procurement Guide", participated in the preparation of the group standard "Flange Forging Enterprise Information Construction Guide", and jointly prepared the "Wind Turbine Whole Forging Tower Flange Manufacturing Technical Specification" and other standards with the national wind energy units and manufacturing units. In the same year, it took the lead in introducing two technical schemes for wind power flange benchmarking, helping 7 peer enterprises to benchmark and meet the standards. In 2020, the forging standard of "wind turbine and tower-ring forging" was formulated, which became the leader of enterprise standard in our province. In 2021, take the lead in the development of green forging enterprise evaluation criteria. In 2022, participated in the preparation of the "Industrial Park Carbon Neutrality Design Guide" and "Industrial Park Carbon Neutrality Evaluation Method" standards.

Shanxi Tianbao Group has always adhered to the business philosophy of "taking honesty as the cornerstone, taking customers as the axis, winning the market with quality" and the enterprise spirit of "learning, surpassing and leading". It has successively obtained ISO9001 quality certification, ISO14001 environment certification, ISO45001 occupational health and safety certification, CE certification, PED/AD certification, PCCC product certification, special equipment manufacturing license certification, and the physical and chemical laboratory has passed CNAS certification, CMA measurement certification, etc.

"Only by focusing on one thing, having no distractions, mastering the core technology, and enhancing the innovation ability and development potential of the enterprise, can we remain invincible in the increasingly fierce market competition." Fan Jingyun is full of confidence in the future.
