我国铝冶炼工业的竞争力分析及发展趋势

Analysis of competitiveness of China’s aluminum industry in the world and its development trend

  • 摘要: 在全面综述我国铝冶炼工业生产和技术现状的基础上,剖析了我国铝冶炼工业发展在资源、能源和环境治理方面所面临的主要矛盾与挑战,在世界范围进行了生产成本竞争力比较与分析,认为制约我国铝冶炼工业可持续发展的主要因素是国内缺乏足够的优质铝土矿资源、电力价格过高、生产技术需进一步优化,所产生的大量固危废难于实现无害化和资源化利用。由此提出了我国铝冶炼工业可持续发展的战略,即严控产能的无序过快扩张并合理布局,优化资源和能源供应结构,实施优质、节能、低耗的产业发展战略以提高核心竞争力,加快实现废气、废水和固废的达标排放及资源化利用。研究结果对我国铝工业进行产业结构调整、实现高质量可持续发展的战略,具有较重要的意义。

     

    Abstract: Aluminum is the second largest metallic material after steel. It is also an indispensable and basic raw material in the economic development of a country. Besides, aluminum is known as a green strategic material due to its efficient recycling performance. China’s aluminum industry has made remarkable achievements in technological innovation and scientific progress through decades of development. However, in recent years, the huge production scale of the aluminum industry has increasingly prominent problems of limited resources, rising energy costs, and environmental pollution. It should be realized that the development and survival of China’s aluminum industry have reached a very critical period. This paper comprehensively studied the current situation of the production and technology of China’s aluminum metallurgical industry. Major contradictions and challenges faced by the development of China’s aluminum industry in the fields of resources, energy, and the environment were revealed. In addition, the competitiveness of the production cost for Chinese alumina refining and aluminum smelting in the world was compared and analyzed. It is shown that the major factors restricting China’s aluminum industry development include the lack of high-quality bauxite resources, high energy costs, the requirement for further improvement of the production technology, and no effective treatment of solid and hazardous wastes. Hence, a development strategy for China’s aluminum industry was proposed, which includes the strict control of the production capacity without out-of-order expansion and establishment of a reasonable industry arrangement, optimization of the resource and energy supply structure, improvement of the production core competitiveness by implementing high-quality, energy-saving, and low consumption strategy, and realizing standardized discharge and resource utilization of waste gas emissions, wastewater, and solid disposals from China’s aluminum industry. The research results of this work are of great significance to the industrial structure adjustment and high-quality, sustainable development for China’s aluminum industry.
