“…Therefore, China's steel industry has become the second largest national emitter of CO 2 after the power industry. In 2015, CO 2 emitted by China's steel enterprises accounted for over 15% of the country's total CO 2 emissions [5,6]. CO 2 emission from steel enterprises is mainly caused by coal combustion.…”

“…China is currently the world's largest steel producer; indeed, the country's steel production accounted for 49.2% of the world's total steel production in 2017 [3]. The energy consumption of China's steel industry accounted for over 20% of the national industry energy consumption in 2017, and the CO 2 emissions from steel enterprises also accounted for over 10% of the country's total CO 2 emissions [4][5][6]. As such, improving the energy efficiency of steel production should be a primary concern for China, especially in times of high energy price volatility.…”

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.

“…Since investing in new process units is a strategic decision in steelmaking with an investment horizon of at least 20 years, future scenarios for prices and availability of energy and materials have to be considered to support decision‐making. Scenario studies such as published by Zhang et al in 2018 are important to identify potential pricing structures, decreasing demands or availability of certain materials, such as recycled scrap in the case of China.…”

This paper presents and reviews the current application fields of mathematical programming in integrated iron‐ and steelmaking research. Three different fields of mathematical programming applications are identified and discussed: unit operation optimization, by‐product gas distribution, and integrated system optimization and design. Based on current research activities in the iron and steel industry, development trends for mathematical programming in integrated iron‐ and steelmaking research, such as the cogeneration of chemicals aided by renewable energy grid integration, are presented.
