Expert Group Demonstration on Key Development Tasks of the “13th Five-Year Planning”
The expert group demonstration on key development tasks of the “13th Five-Year Planning” was successfully held and assessed in the conference center of Hubei University on March 14th, 2015.
The key tasks of major common key system technology for steel slag resources, such as hot resource of steel slag for power generation and preparation of high active auxiliary cementitious materials, etc. It will fill the gaps of the second comprehensive utilization of resources at home and abroad, and has very wide application prospects in metallurgy, thermal power generation, building materials, environmental protection, and construction etc. The continuous researches, especially in recycling utilization of the waste, technical extension of construction industry chain, optimum distribution of resources in building materials, environmental protection and construction industry, establishment of green ecological supply chain model and the major national strategic tasks in “13th Five-Year Planning”, which would enhance the system technologies for disposal of iron and steel industry waste as the international advanced level, and provide strong scientific and technological supports on utilization of the waste in iron and steel industry and the build of the new green industry chain in China.
The “Utilization Research and Industrial Technology of Iron and Steel Industry Waste” is aimed at develop the key major common integrated technology and innovation process of utilization of waste resource in iron and steel industry. Using steel slag thermal power resources (temperature of exhaust gas is 750℃ to 800℃), only by using of 123 million tons of steel slag thermal power resources in 2014 in China, the annual generation power is 14.76 billion kWh. Using 123 million tons of steel slag powder mixed with correction material, it would replace 141 million tons of cement clinker, saving 15.51 million tons of standard coal, with 140 million tons of CO2 emission reduction.
This meeting is chaired by the Provincial Science and Technology Department, experts from Expert Committee of China Cement Association, Yunnan Huixi Iron and Steel Group, Gezhouba Cement Group, Wuhan University of Technology, demonstrated in proofreading “Research on Utilization of Iron and Steel Industry Waste and Industrial Technology”. Mr. Zhang Tianjin, Dean of Development Research Institute of Science and Technology, Mr. Wu Caiqing, Director of Science and Technology Department, Mr. Li Zhaohua, Professor of College of Environment and other members of the project team participated in the meeting.
