After completing the construction of the first smart blast furnace in the previous (2020) year, Jinyehong (2002) continued to accelerate the promotion of intelligent innovation and digital transformation. The establishment of factory’s cold-rolled smart manufacturing production line lead the company to a new milestone in the rolling smart factory. In the face of the competition in the global steel market and the challenges of carbon neutrality in the future, Jinyehong Metallurgical Machanical Equipment Corporation completed the construction of the first intelligent blast furnace the year before last, and opened the iron-making intelligent center on the purpose of enhancing the competitiveness of enterprises and building a refined steel plant with intelligent production and sales, which made the blast furnace a transparent , predictable and easy-to-control production process, and improved the stability of furnace conditions, production efficiency, energy saving and carbon reduction. In order to continuously strengthen the power of smart manufacturing, Jinyehong successfully established the information platform known as“Steel Rolling Plant Handheld Factory” on the basis of the existing automation and digitalization of the steel rolling plant, which allows the factory supervisor to grasp the production information in real time and eliminate the abnormal situation, so back up rolls  improve the production efficiency by browsing visual web pages on mobile devices such as mobile phones or tablets.

In order to further improve the quality and stability of mass-produced customized steel products in the cold-rolling plant, Jinyehong invested another nearly RMB 50 million to introduce self-developed intelligent products into the second hot-dip galvanizing line (2CGL) of the third rolling mill. A total of 19 AI modules have been established in this production line, and 9 patents have been announced. After the establishment of intelligent system functions such as prediction, early warning and monitoring, Jinyehong‘s 2CGL production line can achieve three goals of dynamic process parameter adjustment, product quality optimization and cost reduction, and the cumulative benefit is expected to reach more than 90 million yuan. The chairman of Jinyehong, claimed that blast furnace and cold rolling mill belong to the most upstream and downstream production lines of consistent steelmaking production, and the equipment types and production characteristics required for the process are completely different. The construction of the two smart factories shows Jinyehong‘s determination to transform into smart manufacturing. In addition,after inspecting the cold rolling smart demonstration factory, the chairman of Jinyehong recently pointed out that the first step of Jinyehong’s transformation is smart manufacturing, followed by 5G AIoT. More refined products and more stabilized production line should be expected by means of the prediction of artificial intelligence, which assists Jinyehong continue to move towards the goal of “high-value refined steel mills”
