Group 1 - Anshan Iron and Steel Company (Ansteel) is recognized as a pivotal entity in China's steel industry, often referred to as the "first son" of the Republic's steel industry, contributing significantly to the early industrial development of New China [2][3] - The Ansteel Museum serves as a historical chronicle of the development of China's steel industry, showcasing over a thousand valuable historical photographs and more than ten thousand artifacts, covering a total area of 67,600 square meters [7][9] - The museum has received numerous accolades, including being designated as a national first-class museum and a national model base for patriotic education, highlighting its cultural and educational significance [9][10] Group 2 - The Dagu Mountain Iron Mine, known as Asia's deepest open-pit iron mine, has been in operation since 1916, illustrating the evolution of the iron mining industry in Anshan and its impact on China's steel production [14][16] - Qianshan, located 17 kilometers from Anshan, is a national scenic area known for its rich historical and cultural heritage, attracting visitors interested in both natural beauty and historical exploration [18][23] - The Yushi Museum in Anshan showcases the rich history of jade culture in China, particularly the unique qualities of Xiuyan jade, which has a long-standing tradition of mining and processing [26][29]

Core Viewpoint - The introduction of smart control technology at Nanjing Steel's first steelmaking plant has significantly improved operational efficiency and safety, allowing remote control of steel production processes from a comfortable environment, reducing the need for on-site labor in extreme heat [3][4][6]. Group 1: Technological Advancements - The smart control center allows operators to remotely manage steel production, transforming a previously labor-intensive and hazardous job into a more efficient and safer process [3][6]. - The upgrade of the dust removal system in 2022 has led to a significant reduction in smoke and dust emissions, achieving compliance with national ultra-low emission standards [5][6]. Group 2: Operational Efficiency - Each shift at the steel plant can produce approximately 12 to 14 batches of steel, indicating a high level of productivity and seamless operation [4]. - The implementation of automated sampling systems has made it possible to take samples from molten steel at 1600°C safely and efficiently, reducing the risks associated with manual sampling [6]. Group 3: Working Environment Improvements - The working conditions have improved dramatically since the plant's inception, with modern air conditioning and reduced exposure to hazardous materials, allowing workers to use fewer protective masks [5][6]. - The transition from a traditional glass observation setup to a smart monitoring system has enhanced safety and operational oversight, minimizing the need for workers to be in close proximity to dangerous processes [6].
