On June 5, a seminar on the localization of imported servo valves for special steel enterprises was held in Nanjing, Jiangsu. The meeting was hosted by the Metallurgical Equipment Branch of the China Special Steel Enterprises Association (hereinafter referred to as the "Association") and organized by AVIC Nanjing Servo Control System Co., Ltd. (AVIC 609 Hydraulic Servo Division, hereinafter referred to as AVIC Servo). The theme of the meeting was "Promoting the localization of electro-hydraulic servo valves and promoting the high-quality development of special steel enterprises." The meeting analyzed the pain points, blockages and difficulties in the localization of equipment and spare parts for special steel enterprises, introduced the business scope of AVIC Servo and the servo valve replacement model, and shared the results of the localization application of servo valves to promote the quality upgrade and supply security of equipment management in special steel enterprises.

Yu Kou, senior consultant of China Special Steel Enterprise Association, and Wang Yongjian, chairman of Metallurgical Equipment Branch, delivered speeches to the conference respectively. Zhang Wenqiang, chairman of AVIC Nanjing Servo Control System Co., Ltd., delivered a keynote report. Nearly 100 representatives from special steel enterprises attended the meeting.

Yu Kou said in his speech that the association and the Metallurgical Equipment Branch actively explored the collaborative work of the industrial chain and included the construction of a supply and demand cooperation platform for the upstream and downstream of the industrial chain in this year's key work. At present, the special steel industry is committed to the transformation and upgrading of high-end, intelligent and green, among which the localization of high-end equipment is particularly critical, striving for breakthroughs and avoiding being controlled by others. The association will carry out in-depth cooperation with various domestic metallurgical equipment companies in terms of platform exchanges, enterprise services, and industrial chain improvement, provide good services for the localization of metallurgical equipment, and jointly promote the progress and development of the special steel industry. 

Wang Yongjian introduced that the Metallurgical Equipment Branch is specifically responsible for the localization of metallurgical equipment and spare parts. By the end of 2023, the branch had completed nearly 400 localization projects for equipment and spare parts. In 2024, the branch will intensify its efforts, continue to do a good job in the localization of high-end key equipment and spare parts, and gradually solve the problem of domestic substitution of some foreign equipment and spare parts.  

At the meeting, Zhang Wenqiang, chairman of AVIC Servo, introduced the business situation of AVIC Servo. He said that in response to the working conditions of large vibration, high water vapor and high temperature in the steel industry, AVIC Servo applied aviation technology to the production of servo valve controllers, using three-layer protection technology to prevent water vapor from penetrating, and solidifying components to prevent vibration.

AVIC Servo technicians introduced the localization substitution model of imported servo valves and the development and application of electro-hydraulic servo valves. Representatives from steel companies introduced the replacement application of AVIC Servo servo valves in Shougang Hot Rolling 1580 and Fushun Special Steel and other steel companies.

It is reported that AVIC Servo is the main supplier of servo valve solutions for aviation, aerospace, metallurgy, and power equipment. In the steel and metallurgical industry, more than 2,000 609 servo valves are in service every year, and there are tens of thousands of 609 servo valves in stable operation across the country. The difference between the set value and feedback value of AVIC Servo servo valve is between 0.5% and 1.1%, while the difference of foreign competitors in the same position is between 4.9% and 5.6%. In addition, AVIC Servo servo valves have the same installation dimensions and electrical interfaces as foreign competitors, and can be directly substituted for each other without changing any control parameters.
