Xingcheng Special Steel's large blast furnace won the title of "Winning Furnace" in the country again

Time: Sep 23, 2020 Views: 0

On July 1, the results of the "National Key Large-scale Energy-consuming Steel Production Equipment Energy Saving and Consumption Reduction Benchmarking Competition" in 2018 were released. Xingcheng Special Steel's 3200 cubic meter blast furnace was in the evaluation of 3000 cubic meters (inclusive) to 4000 cubic meters , Won the honorary title of National "Excellent Furnace". This is the fourth consecutive year that Xingcheng Special Steel's large blast furnace has won the honor since participating in the industry benchmarking competition in 2014.

Over the years, Xingcheng Special Steel's large blast furnace has continued to actively promote energy conservation and emission reduction from four aspects. The first is to optimize the charging system, improve the utilization rate of gas, and reduce the energy consumption of the whole process of ironmaking under the guidance of scientific concepts; the second is to continuously innovate, through the improvement of the operation method of gas release and repairing the broken cooling wall of the furnace body. Innovative reforms to achieve the goal of energy conservation and environmental protection; the third is to use multi-dimensional lean index research as the starting point to carry out a number of lean projects such as "reducing the average silicon content of the molten iron in large blast furnaces" and "increasing the coal ratio" to reduce costs and reduce consumption. Help; Fourth, take the energy and environmental management system as the foundation, sort out waste points, implement the economic responsibility assessment system, and keep the blast furnace energy-saving and environmental protection under constant monitoring.

Xingcheng Special Steel's large blast furnace won the title of

The "National Benchmarking Competition for Energy Conservation and Consumption Reduction of Key Large-scale Energy-Consuming Steel Production Equipment" is jointly organized by the National Committee of the China Machinery, Metallurgical and Building Materials Trade Union and the China Iron and Steel Industry Association. The expert group and representatives of participating companies jointly deliberate and vote. Has a certain degree of authority.

The energy-saving and consumption-reduction benchmarking competition covers all blast furnaces of 2000 cubic meters and above and converters of 120 tons and above in the country, focusing on the comprehensive coke ratio of blast furnaces, coal injection ratio, TRT ton iron power generation, steelmaking process energy consumption, and converter gas recovery. , Steam recovery and more than 20 indicators were evaluated.
