Core Insights - The article discusses the mining robot industry chain, highlighting its similarities to the general robotics industry chain, which includes upstream components, midstream manufacturing, and downstream applications [1][3]. Industry Overview - The mining robot industry relies heavily on international suppliers for core components, with major players like the "Four Families" of robotics controlling key parts, while companies like NVIDIA and Horizon dominate the AI chip market [3]. - Key manufacturers in the midstream include companies such as CITIC Heavy Industries, Zhengzhou Coal Mining Machinery, and China Railway Construction Heavy Industry [3]. Regional Analysis - The mining robot industry is well-developed in regions such as Guangdong, Shaanxi, Shandong, Jiangsu, and Shanxi, with Guangdong and Jiangsu having strong upstream component and equipment manufacturing capabilities [4]. - Other regions with a complete industry chain include Beijing, Hunan, Liaoning, Shanghai, Anhui, and Fujian [4]. Cost Structure - The core components of mining robots, including controllers, servo systems, and reducers, account for 70% of the total cost, with reducers being the most expensive at 35% [8]. - Controllers represent about 15% of the total cost, while servo systems account for 20% [8]. Value Chain Analysis - The growth potential for suppliers of the robot body is limited compared to upstream and downstream players, with the highest profit margins found in reducers (40%), followed by servo systems and integrated systems (35%) [11]. - The profit margin for controllers is 25%, while the robot body has the lowest margin at 15% [11].

Core Insights - The article discusses the materials used in mining robots, emphasizing the importance of corrosion-resistant coatings and cast iron components for durability in harsh mining environments [1][3][4]. Material Overview - Corrosion-resistant coatings are essential in mining due to the severe corrosion caused by acidic gases and saline mist, which can damage metal parts and electronic components of robots [3]. - The coatings form a dense protective layer that reduces direct contact with corrosive substances, thereby extending the lifespan of mining robots [3]. - Cast iron, particularly wear-resistant varieties, is favored for structural components of mining robots due to its high strength and durability against wear [4]. - High-temperature alloys are also utilized in mining robots for parts that endure high temperatures and complex stresses, with domestic production reaching levels comparable to international standards [2][4]. Production Data - In 2023, China's production of corrosion-resistant coatings reached 7.15 million tons, accounting for approximately 20% of the total paint market, with a projected increase to 7.52 million tons in 2024 [3]. - The production of cast iron components in China was 51.95 million tons in 2023, reflecting a year-on-year increase of 250,000 tons, with a compound annual growth rate of 13.7% from 2016 to 2023 [4].
