OURGAME(HK:06899) Zhong Guo Huan Jing Bao·2025-04-24 04:04Core Viewpoint - The steel industry, as a crucial pillar of the national economy, faces significant energy-saving and emission-reduction pressures while providing essential materials for infrastructure. Angang Lianzhong (Guangzhou) Stainless Steel Co., Ltd. is committed to green development and actively responds to the national "dual carbon" goals through various energy-saving and emission-reduction measures, achieving steady economic growth alongside considerable environmental benefits, aiming to become a benchmark for green transformation in the steel industry [1]. Group 1: Technological Innovations - Technological innovation is the core driver for Angang Lianzhong's energy-saving and emission-reduction efforts. The company has adopted a super filtration + secondary reverse osmosis process to replace traditional water treatment technologies, significantly improving water quality and reducing equipment failure rates, water resource waste, and energy consumption [3]. - Since the implementation of the new water treatment system in January 2024, the company has achieved a cumulative efficiency increase of over 4 million yuan, demonstrating the practical value of technological innovation in energy-saving and emission-reduction [3]. Group 2: Wastewater Management - Angang Lianzhong has optimized its wastewater treatment processes and upgraded equipment to effectively control sludge moisture content and maintain sludge treatment levels despite a 55,000-ton increase in steel production in 2024. This is attributed to refined management and technological innovations [4]. - The company has introduced advanced dehydration technologies and automated control systems, significantly reducing waste acid concentration and treatment volumes, thereby lowering pollutant emissions and treatment costs while enhancing economic benefits [4]. Group 3: Gas Emission Reduction - The company has optimized the cooling mode of reaction furnaces and upgraded combustion equipment to reduce liquefied petroleum gas (LPG) consumption. Technical modifications to the combustion system have improved energy efficiency and reduced pollution emissions while lowering production costs [5]. - In 2024, Angang Lianzhong achieved the best historical performance in LPG consumption per ton of steel, enhancing its market competitiveness [5]. Group 4: Water Resource Management - Angang Lianzhong has implemented a multi-dimensional water-saving and efficiency-enhancing system through the optimization of its circulating water management. The introduction of a "tiered water use" model prioritizes high-quality recycled water for processes with stringent water quality requirements [8]. - The company has switched its water sources for processes like steelmaking and cold rolling from tap water to recycled water, achieving a cumulative cost reduction of 2.276 million yuan and a 45% reduction in wastewater discharge since the system's operation began in July 2023 [8]. Group 5: Future Outlook - Angang Lianzhong will continue to uphold its green development philosophy, exploring advanced technologies such as waste heat recovery and hydrogen smelting to further reduce energy consumption. The company aims to enhance sludge reduction and treatment through process optimization and technological innovation [9]. - The company plans to deepen water resource utilization efficiency and increase management investments to promote recycling and reduce wastewater discharge, contributing to the "dual carbon" goals and providing replicable green development experiences for the industry [9].
