Abstract
China produced 49.2% of the world’s total steel production in 2017. From 1990 to 2017, the world’s total steel production increased by 850 Mt, of which 87% came from China. After 30 years of rapid expansion, China’s steel industry is not expected to increase its production in the medium and long term. In fact, the industry is currently in the stage of industrial restructuring, and great changes will arise in production structure and technical level to solve pressing issues, such as overcapacity, high energy intensity (EI), and carbon emission. These changes will directly affect the global energy consumption and carbon emissions. Thus, a review of China’s steel industry is necessary to introduce its current situation and development plan. Therefore, this paper presents an overview of the Chinese steel industry, and factors involved include steel production, production structure, energy consumption, technical level, EI, carbon emission, scrap consumption, etc. In addition, four determinants are analyzed to explain the EI gap between China and the world’s advanced level. In addition, comparison of steel industries between China and the world, development plans for energy savings, and emission reduction are also included in this paper to give readers a clear understanding of China’s steel industry.
Highlights
Steel production is an energy, resource, and pollution-intensive process [1,2]
Works on the steel industry from a technical point of view are available in the literature, the comprehensive review of China’s steel industry is still necessary to give readers and a clear energy saving potential of China has been in scientific papers
This paper presents an analysis of the reasons behind the energy intensity (EI) gap between China’s and the of production and its main sources
Summary
Steel production is an energy-, resource-, and pollution-intensive process [1,2]. China is currently the world’s largest steel producer; the country’s steel production accounted for 49.2% of the world’s total steel production in 2017 [3]. Works on the steel industry from a technical point of view are available in the literature, the comprehensive review of China’s steel industry is still necessary to give readers and a clear energy saving potential of China has been in scientific papers. The work presented in this paper is of a unique for the and steel industry, as an extensive of development and present situation steel study production consumption in China;review (2) the. Technologies, This paper discusses (1) the development implementation ratewas of conducted major energy-saving gas recovery and utilization, and and present situation of steel production and consumption in. The factors considered include scrap ratio (SR), production structure, conservation in China’s steel industry are introduced and analyzed These plans include energy structure, and industrial concentration.
