Natural Gas Consumption

The existing modern conceptual approaches to the formation of an assessment of the natural gas consumption strategy in the steel industry do not allow assessing comprehensively all the processes that occur in the enterprise affecting the efficiency of natural gas consumption. Due to the fact that natural gas acts an important role as a universal energy resource, both in the economy and in international politics, the modern strategy for assessing the consumption of natural gas in the steel industry is becoming a key factor in increasing competitiveness and guaranteeing sustainable economic growth of the country's steel industry. The article proposes a conceptual approach to the development of the model in order to assess the strategy of natural gas consumption at iron and steel enterprises, which allows timely management decisions to be taken to increase the organization of efficient energy consumption at the enterprise. Based on the proposed conceptual approach to assessing the strategy of natural gas consumption at the iron and steel industry, it can be stated that this assessment is interconnected with the assessment of the integral criterion for the implementation of the goals of organizing effective energy management.

Hierarchy Process

The relations between production process and energy consumption are made an in-depth application analysis and theory study with theory of systematic energy-saving , technique of intelligence analysis and optimization based on the background of study on energy-saving and reduce energy consumption. Making intensive research on theories of systematic energy-saving and analyzed with function mechanism and quantitative relation of the main production system, auxiliary production system and energy conversion system. It put forward the energy flow direction and energy consumption in each production process and the influence of material flow on energy consumption in iron and steel industry. The sequence of all kinds of material influence comprehensive energy consumption per ton steel and energy quantitative target of all factors influence energy consumption are worked out with improved fuzzy AHP(Analytic Hierarchy Process) which study of comprehensive energy consumption in typical iron and steel production process from the point of system. It has great immediate significance to guide drawing the scientific plan of economy-saving and reduce energy consumption in iron and steel industry

The Stability

The sinter quality and the stability of composition could directly affect the yield, quality and energy consumption of ironmaking production. It is important for iron and steel industry to steadily control sinter chemical composition and analyze sintering energy consumption. The MATLAB m file editor was used to write code directly in this paper. A predictive system for two important sinter chemical composition (TFe and FeO), sinter output and sintering solid fuel consumption of was established based on BP neural network, which was trained by actual production data.) The application results show that the prediction system has high accuracy rate, stability and reliability, the sintering productivity was improved effectively.

Green Development

Analyzing the potential for green development and its influencing factors is an important part of the energy savings and low-carbon economic growth of China’s iron and steel industry (ISI). Many studies have concentrated on improving the ISI’s energy use and pollution control efficiencies, analyzing the influencing factors from the perspectives of regions and firms. However, no study has focused on measuring the provincial green development efficiency (GDE) in the ISI. The selected driving forces of the GDE do not consider regional or industrial characteristics. In this study, based on provincial panel data for 2006–2015 in China, the GDE of the Chinese ISI was evaluated using the super-slack-based measure (super-SBM) model. China’s 28 provinces were divided into different groups through cluster analysis. Then, a Tobit model was constructed to explore the factors influencing the GDE. The key results show the following: (1) The GDE values decline, fluctuating from 0.628 in 2006 to 0.571 in 2015, decreasing by 1.1% annually. Among the provinces, wide differences exist in the GDE values for the ISI, with the highest average GDE value being observed in Beijing and the lowest in Shanxi. (2) The provinces with high R&D expenditure inputs and high GDE values are mostly located in the eastern region, while the provinces with low R&D expenditure inputs and low GDE values are located in the central and western regions. (3) The export demand, property structure, and capital investment have significant positive effects on the ISI’s GDE in the eastern and western regions, while the energy consumption structure and industry scale have negative impacts on the improvement of the GDE in the central region. (4) Specific policy recommendations for sustainable development in the ISI mainly include further strengthening investment in R&D, expanding exports, adjusting energy consumption structures, and deepening the reform of stated-own enterprises.

In this paper, we find that factors which affect energy consumption are steel ratio coefficient and process energy consumption by analyzing energy consumption of every process in integrated steel works. On this basis we point out the main reason for the high energy consumption of iron and steel industry in China is that integrated steel works examine the production process without system energy saving ideas. Therefore we propose the countermeasures of energy saving in iron and steel industry in China in aspects of energy management and control center, iron-making system, steel-making system, steel rolling system, as well as secondary energy recovery, which is aimed at providing a way for energy saving and emissions reduction of iron and steel industry in China.
