Riyue Heavy Industry: Seize the opportunity in the “wind”

Recently, the list of the 100 fastest-growing enterprises in Zhejiang Province in 2021 was released, and Riyue Heavy Industry ranked 10th in the province. The Ningbo manufacturing company ranked 204th on the list of the top 500 global new energy companies in 2021 previously released.

“In 2018, the output of our company’s wind power castings was only 150,000 tons. In 2020, the total output of castings will be around 460,000 tons, of which wind power castings will be 380,000 tons.” said Han Song, the administrative director of Riyue Heavy Industry. In just a few years, Japan The monthly output of wind power castings of Heavy Industries has achieved a significant leap. The domestic market share of related products has increased to more than 30%, and the international market share has increased to more than 20%.

In the finished product warehouse of Riyue Heavy Industries, there are piles of various castings with weights ranging from dozens of kilograms to dozens of tons. For Riyue Heavy Industries, which can produce nearly 500,000 tons of castings a year, this is only a small part. After the completion of the 180,000 tons of sea-mounted key castings project, Riyue Heavy Industry will have an annual production capacity of more than 400,000 tons of wind power castings.

Starting from an ordinary foundry in Dongwu Town, Yinzhou District, until 2019, the wind power castings produced by the company won the title of single champion product in the manufacturing industry awarded by the Ministry of Industry and Information Technology. Riyue Heavy Industries is doing “big pieces” of key castings for large-scale heavy industry equipment. .

In this industry, everyone knows the organizational performance and other data of each product, but whether the product can be presented perfectly varies from company to company. Just like cooking a dish, the recipe is public, but different people make it. There is a difference between dishes. The key is the “heating” in the manufacturing process, which is the core process technology. When “heating” is practiced to perfection, the performance of the product can be perfectly presented in the casting manufacturing process, while avoiding product defects such as porosity and shrinkage.

It is precisely by virtue of various core and key technologies that Riyue Heavy Industry has broken new ground in the subdivision of wind power castings and has become the industry leader. And this leading company “specializes in difficult parts and specializes in large parts”, further expanding its advantages. Han Song said that Riyue Heavy Industry has successfully developed wind power castings for wind turbines above 12MW, which further supports the development of large-scale wind turbines.

In addition to the craftsmanship, Riyue Heavy Industries has another magic weapon, which is to continuously pursue high quality and low price, and to provide customers with more value-added services.

In the course of years of research and development, Riyue Heavy Industry has always emphasized the need to improve the performance of castings while reducing the production cost of castings. On this basis, the company has worked hard to break through difficult points. Under the trend of large-scale wind turbine development, the company has used its own research and development of “large thick section ductile iron castings microstructure and performance control key technology” to make nearly 100-ton castings better Technical Support. At present, Riyue Heavy Industry has 108 authorized patents, of which 56 are invention patents.

“Under the background of’dual carbon’, renewable clean energy represented by wind power and photovoltaics is the future development trend.” Han Song said that he is very confident about the prospects of the wind power casting industry. On the basis of going further in the field of wind power castings, Riyue Heavy Industry will continue to expand its business in other fields, so that the “master” of this table is not only rich in categories, but also “taste” better.

Interview Notes

As one of the fastest-growing enterprises in Zhejiang Province in 2021, the development of Riyue Heavy Industry is inseparable from the core process technology it has mastered. When the relevant data of the product is public, companies want to run faster, not only to work hard on the details, but also to have their own hard power, “specialize in difficult parts, specialize in large parts” is the embodiment of Riyue Heavy Industry’s strength. On this basis, only by seizing the opportunity and riding on the “wind” can we embark on a “championship road” of our own.
