On the morning of July 27, 2022, the scientific and technological achievement of "Research and Application of Key Technologies for Digital Manufacturing of Steel Cord" developed by Shandong Daye Co., Ltd. successfully passed the expert appraisal organized by the China Petroleum and Chemical Industry Federation.
The appraisal committee is composed of 9 expert leaders, including Zhang Liqun, academician and vice president of Beijing University of Chemical Technology, and Zhang Song, professor of Shandong University. Wang Yimin, director of the China Petroleum and Chemical Industry Federation, presides over the meeting.
Company Party Secretary Dou Baosen, Chairman Dou Yong, General Manager Zheng Hongxia, and others accompanied the committee for on-site research and visited the digital workshop and intelligent inspection center for steel curtain lines.
After listening to the research summary report on steel cord and reviewing relevant documents, the appraisal committee highly praised our company's intelligent achievements. The committee pointed out that Daye Group has always maintained a leading position in the metal skeleton material industry, leading the development direction of the industry, especially in the areas of intelligence and digitization, and has achieved significant results. It deeply integrates professional technologies in informationization, automation, intelligence, and software and hardware systems, and has developed and designed intelligent logistics systems, intelligent sorting systems, intelligent detection systems, intelligent timeliness, container allocation, and packing systems.
Our company has been carrying out intelligent upgrading and transformation of the steel curtain production line since 2019. The implementation of this project not only achieved the expected effect of "reducing staff and increasing efficiency", but also significantly improved labor productivity, effectively alleviated the problems of "labor shortage" and labor structure adjustment in enterprises, achieved multiple results such as reducing energy consumption, reducing waste, reducing safety injuries, improving product quality, enhancing operational efficiency, improving human-machine efficiency and production environment, and achieved the goal of green production. After gaining mature experience in the steel curtain line intelligent project, we will gradually promote its application within the company from point to surface, promote the comprehensive intelligent transformation and upgrading of the enterprise, drive the green and intelligent development of the entire industry chain, and safeguard the safe operation of tires worldwide!
Finally, the members of the appraisal committee unanimously agreed that the technical information submitted by Daye Corporation is complete, detailed, and meets the appraisal requirements. We have designed and developed equipment networking data collection technology and information production management system to address the problems of key processes, multiple process parameters, and difficult state control in steel curtain lines. This system achieves interconnectivity between "process islands" and "information islands"; We have developed digital control and linkage technologies for processes such as steel cord pretreatment, stretching, electroplating, wet stretching, and twisting, which have improved the precision control level of the production process; We have designed and developed an automated detection technology for residual torsional force of steel curtain lines, which has improved detection efficiency and accuracy. We have further developed intelligent packaging and factory logistics technology for steel curtain lines, achieving transportation safety and reducing logistics costs. This achievement has successfully achieved the digital manufacturing of steel cord, significantly improving production efficiency and product quality consistency compared to traditional processes, significantly reducing production costs and energy consumption, and achieving significant economic and social benefits. The production process of this technology meets environmental protection requirements and has overall reached the international advanced level, playing a leading role in the high-quality development of the steel curtain industry.
