Moving towards integrated governance of water and energy requires balancing tradeoffs and taking advantage of synergies through specific technology choice. However, the water-energy conservation relationships of individual conservation measures in industries other than the water and energy sectors have not been investigated in detail. This study develops a hybrid model to estimate the associated water impacts of individual energy conservation measures, using China's iron and steel industry as a case study. The results reveal that water-energy tradeoffs exist in the production process adjustment, which is conventionally promoted as a key energy-saving measure in iron and steel industry. It is found that replacing the Blast Oxygen Furnace (BOF) process with the Electric Arc Furnace (EAF) in 2007 could save 131–156 kg coal equivalent (kgce) (13.2–15.7%) of embodied energy per ton of crude steel (tcs) at the expenses of an additional 2.5–3.9 m3/tcs (10.6–16.4%) of water footprint. Nineteen energy efficiency technologies are studied in this research, and most of them are identified as having water-saving synergies except for the Low Temperature Rolling Technology. Taking these water impacts into consideration can update the priority ranks of the technology choices and inform policy decisions. Although this study focuses on China's iron and steel sector, the methods and analysis can be extended to other countries, sectors, technologies and environmental impacts. © 2017 Elsevier Ltd

The equipment, capacity, output and production target about China EAF steelmaking in recent ten years have been analysed, and the achievement about modern and large-scale equipments of EAF has been affirmed. Then the current challenge and difficulty of EAF steelmaking development, such as less competition and insufficient policy support, have been summarized. During "13th Five-Year", the dissolution of excess capacity of domestic iron and steel will be promoted, the energy conservation and environmental protection will be paid further attention, and the situation of scrap and electricity supply will be improved. Considering those important factors, the viewpoint has been proposed that the domestic EAF steelmaking will come into an period of important opportunities. © 2017, CISRI Boyuan Publishing Co., Ltd.

In the current article, the issues of development and transfer of the world steel industry, new normal and outlook of Chinese steel industry, international steel trade and Chinese steel import and export etc are discussed. As the biggest steel exporter in the world, Chinese steel is confronted with varied trade protection measures although it is satisfying demand of overseas users. In this article some ideas on how to evaluate the export of Chinese steel objectively are provided, and how to respond the trade protection measures against Chinese steel as well as strategies adopted for Chinese steel import and export over the coming years are analyzed comprehensively. © 2017, CISRI Boyuan Publishing Co., Ltd.

The sinter strength is guaranteed by liquid phase formation and agglomeration of the unmelted materials. Liquid phase formation and fluidity of iron ores are the basic which have significant influence on the yield and quality of the sinter. In this study, first the thermodynamic analysis of liquid phase formation was carried out with FactSage on seven kinds of domestic and overseas iron ores. Second, the generation speed, the amount of liquid phase and fluidity index of the sinters were measured and analyzed. The results indicated that the sinter liquid formation increased with rising temperature. When the reaction temperature was 1050 °C, a part of iron ore generated some liquid phase at a rapid speed, and the production of the liquid phase of most iron ores reached the highest level at about 1350 °C. As there is a large difference about liquid phase fluidity between different iron ores, the iron ores with worse fluidity could be used for matching with the iron ores of better fluidity in order to meet the quality requirements of the sinter. © 2017 EDP Sciences.

Under the pressures of both the decrease of high-grade high-quality iron ore resources and the increase of raw material costs, the iron and steel enterprises in China turn to adopt iron ores which contain special elements such as nickel, manganese, etc. in the sintering blend. Analytical reagents were used for sintering experiments, and the sinters were analyzed with X-ray diffraction, scanning electron microscopy and mineralogical microscopy to study the effect of nickel on the silico-ferrite of calcium and aluminum (SFCA) bonding phase formation during sintering. The results indicated that SFCA was divided into nickel-containing and nickel-free areas due to the presence of nickel. The increasing content of nickel would greatly reduce the content of SFCA and promote the formation of calcium aluminum silicate. A great deal of Fe2O3 participated in the crystal transition to Fe3O4, reducing the amount of Fe2O3 involved in the formation of calcium ferrite. When the blending ratio of NiO, which is used to provide the nickel in the sintering process, is less than 3%, the calcium ferrite is in substantially interleaving corrosion with hematite and magnetite. Both the porosity and silicate glass phase content are low, which contributes to the sintering production. © 2015 Central Iron and Steel Research Institute.

Reasonable control on CRI (coke reaction index) is one of the key factors for BF (blast furnace) low-carbon smelting. However, there are contrary opinions. One is increasing CRI to improve reaction efficiency in BF and the other is decreasing CRI to suppress coke degradation in furnace. Different methods are adopted to realize effective catalysis (increasing CRI) and passivation (decreasing CRI) of coke. Simulation tests of coke in BF lumpy zone under gradual temperature rising have been done. Effect of CRI on gas composition, ore reduction, burden column permeability and heat reserve zone's temperature under non-isothermal condition are studied. Then combined with iron making calculations, a novel BF operation suggestion is proposed as coke nut with small size be catalyzed and mixed with ore while skeletal coke with large size be passivated and separately charged into BF. © 2013 Central Iron and Steel Research Institute.

To solve the tardiness-problem caused by unqualified product which affected by dynamic factors, such as equipment failure, staff skills and raw material defects, a dynamic substitute model was presented by considering the minimized delay time and substitute-times among orders. According to the characteristics of problem, it was proved as NP complete problem. A dynamic product substitute algorithm based on some substitute rules was proposed among orders of different agreed delivery dates. The effectiveness of algorithm was tested based on simulation, and the results showed that the algorithm could get optimal solution to meet production requirements. At the same time, the effect on total delay time and substitute times was compared when product categories, batch-size and order-size were changed. © 2016, Editorial Department of CIMS.

This study estimates how carbon price affects diffusion of low carbon technologies using data collected from 60 iron & steel companies in China. The analysis indicates that the industry is familiar with related key energy saving and low carbon technologies and has made much progress in energy saving, but efforts in carbon management need improving. An average payback time threshold of 4.1 years was found as regards decision in invest in technology. The three target technologies were adopted by companies to different extents. Carbon emissions pricing was found to be ineffective in promoting the scale-up or further adoption of economically advantageous technologies such as dry top pressure recovery turbine (Dry TRT) and energy management centre (EMC) technology. A moderate carbon price for sintering waste heat recovery power generation (Sintering WHR), which has adoption potential in China's iron & steel industry, may generate comparatively significant effects for diffusion. This research sheds light on how diffusion of low carbon technologies would be affected and the consequences thereof on climate policy development for the target sector in China. © 2016 Elsevier Ltd.
