2026年中国钢渣处理行业发展历程、产业链、利用规模、重点企业及趋势研判：环保要求提升处理需求，钢渣利用规模将进一步扩张[图]

Core Viewpoint - The comprehensive utilization of steel slag in China is gaining momentum due to increased emphasis on environmental protection and resource recycling, with significant implications for the steel industry's sustainable development and cost reduction [1][11]. Group 1: Industry Overview - The steel slag treatment industry is essential for managing by-products from steel production, which contain valuable metals and harmful substances [3][4]. - Steel slag treatment methods include magnetic separation, gravity separation, particle size classification, and acid washing, all aimed at reducing environmental pollution and recovering valuable resources [3][4]. Group 2: Industry Development History - The development of China's steel slag treatment industry can be divided into three phases: the initial phase (1950-1980) with negligible resource utilization, the preliminary development phase (1980-2005) with basic recovery methods, and the rapid development phase starting in 2015 [4][5]. Group 3: Industry Chain - The steel slag treatment industry chain consists of upstream steel production generating slag, midstream treatment companies converting slag into reusable resources, and downstream applications in construction materials, agriculture, and environmental remediation [7][8]. Group 4: Current Industry Status - China produces over 100 million tons of steel slag annually, with a projected production of approximately 151 million tons by 2025, despite a low resource utilization rate leading to significant environmental concerns [10][11]. - The steel slag stockpile is expected to reach about 1.656 billion tons by 2025, highlighting the urgent need for effective treatment and utilization [10][11]. Group 5: Key Companies in the Industry - Notable companies in the steel slag treatment sector include Zhengzhou Water Energy Saving Technology Co., Jiangsu Ronda New Materials Co., and Shanghai Zhongcai Environmental Engineering Technology Co., among others, focusing on innovative and efficient treatment solutions [2][12]. Group 6: Industry Development Trends - The steel slag treatment industry is expected to evolve towards high-value and refined resource utilization, emphasizing the extraction of valuable metals and the production of high-performance materials [14]. - There is a growing focus on low-carbon and environmentally friendly processes, integrating treatment with steel production to minimize carbon footprints [15]. - The adoption of smart technologies, including IoT and AI, is anticipated to enhance treatment efficiency and resource recovery rates [16].
