In 2023, China First Heavy Industry Group announced that its carefully developed "Hualong One" improved takeover section forgings have undergone strict performance inspections, and all indicators have reached or exceeded expectations, showing excellent performance, marking my country's nuclear power equipment manufacturing A major breakthrough has been made again in the field.

As the first nuclear power equipment component with innovative design in China, this "Hualong No.1" improved takeover section forging not only adds DVI takeover design in appearance, but also comprehensively optimizes and upgrades in manufacturing process and material selection. The substantial increase in the difficulty of its manufacturing has put forward extremely high requirements for forging technology, material science and quality control.

With its deep accumulation and innovation ability in the field of nuclear power equipment manufacturing, China First Heavy Industry Group has successfully overcome a number of technical difficulties. In the forging manufacturing process, the company adopts advanced forging technology and precision numerical control equipment to ensure the dimensional accuracy and surface quality of forgings. At the same time, through in-depth research and analysis of material properties, the company has selected the most suitable materials, and through fine heat treatment process, the forgings have excellent mechanical properties and corrosion resistance.

In terms of performance inspection, China Yizhong Group has conducted a series of rigorous tests in strict accordance with international standards and industry standards. After testing, this "Hualong No. 1" improved take-over section forging performs well in key indicators such as strength, toughness, and corrosion resistance, and fully meets the design requirements and use requirements. Its excellent performance not only provides a strong guarantee for the safe and stable operation of nuclear power equipment, but also injects new impetus into the development of nuclear power in China.

As a third-generation nuclear power technology independently developed by China, "Hualong No.1" has independent intellectual property rights and export rights. The successful development of this improved takeover section forging not only demonstrates the strong strength of China Heavy Industries in the field of nuclear power equipment manufacturing, but also further consolidates my country's position in the global nuclear power market. In the future, with the continuous promotion and application of "Hualong No.1" nuclear power technology, it is believed that China's nuclear power industry will usher in a broader development prospect.
