Qian Zhan Wang·2025-05-29 08:40Core 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].
