Intelligent manufacturing, defined as the integration of manufacturing with modern information technologies such as 5G, digitalization, networking, and intelligence, has grown in popularity as a means of boosting the productivity, intelligence, and flexibility of traditional manufacturing processes. The steel industry is a necessary support for modern life and economic development, and the Chinese steel industry’s capacity has expanded to roughly half of global production. However, the Chinese steel industry is now confronted with high labor costs, massive carbon emissions, a low level of intelligence, low production efficiency, and unstable quality control. Therefore, China’s steel industry has launched several large-scale intelligent manufacturing initiatives to improve production efficiency, product quality, manual labor intensity, and employee working conditions. Unfortunately, there is no comprehensive overview of intelligent manufacturing in China’s steel industry. We began this research by summarizing the construction goals and overall framework for intelligent manufacturing of the steel industry in China. Following that, we offered a brief review of intelligent manufacturing for China’s steel industry, as well as descriptions of two typical intelligent manufacturing models. Finally, some major technologies employed for intelligent production in China’s steel industry were introduced. This research not only helps to comprehend the development model, essential technologies, and construction techniques of intelligent manufacturing in China’s steel industry, but it also provides vital inspiration for the manufacturing industry’s digital and intelligence updates and quality improvement.

The production and development of the ironmaking process in China are crucial for energy saving, emission reduction and transformation and promotion processes of iron and steel industry. In order to fully understand the production and techniques of ironmaking blast furnace in China, the production and operation indexes of large blast furnaces were analysed in this paper. Then challenges of the ironmaking in China were discussed. On this basis, the future development of ironmaking in China was further analysed. The study will contribute to understanding the state of ironmaking process of China.

This article first presents the characteristics of the iron and steel industry of China during 2018. Then the production, raw material and operation indexes of the large blast furnaces of China in 2018 are introduced. In addition, some thoughts of intelligent manufacturing in the ironmaking process are specifically analysed. The study will help to understand the production and intelligent manufacturing of the ironmaking process in China.
