Finally, the evaluation committee announced the evaluation opinions: under the background of green and low-carbon development, the project has developed a new top-burning hot blast stove with high efficiency, low carbon, green cleaning, high temperature and longevity and its key technologies around common technical problems such as efficient combustion, ultra-low emission, safe and stable operation of blast furnace hot blast stove. Innovative development of high efficiency, low carbon, clean combustion technology of top combustion hot blast stove. A technical standard system for the design, manufacture, selection and configuration of refractory materials for new top-fired hot blast stoves has been established. Research and development of low-stress-non-superheated hot blast furnace body and pipe longevity technology, design and development of low-stress hot blast furnace body and hot blast pipe system. The hot blast stove combustion dynamic precise control model and intelligent information physical system (CPS), hot blast stove furnace and pipeline system all-weather intelligent monitoring system were developed. This achievement has been authorized 37 invention patents (including 4 international patents), formulated 10 national and industry standards and norms, and published more than 60 academic papers. The technology is applied to India's JSW Steel No.5 blast furnace (5872 m), Shougang Jingtang No.3 blast furnace (5500m), Shougang Qiangang No.2 blast furnace (2650m), Zhongtian (Nantong) Steel No.2 and No.3 blast furnaces (2400 m), Baowu Meigang No.2 blast furnace (1280 m), Hegang Serbia Steel No.2 blast furnace (1595 m), Russia's MMK Steel No.7 blast furnace (1280 M) and more than 780 hot blast stoves of more than 240 blast furnaces at home and abroad, it has achieved remarkable economic, social and environmental benefits, and has broad application prospects. The evaluation committee believes that the results have reached the international leading level.
