Embodiment Construction
[0028] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, detailed description will be given below with reference to the accompanying drawings and specific embodiments.
[0029] The iron and steel industry has a huge output scale and an outstanding historical contribution, which is of great significance to supporting the future development strategy of the national economy and society. At the same time, the carbon emission environment and policy pressure are becoming more and more severe, and zero or low carbon breakthrough technology has become the proposition of the times in the field of steel manufacturing. To this end, domestic and foreign countries are vigorously developing cutting-edge technologies for carbon reduction and carbon resource reuse. Blast furnace ironmaking has large capacity and high efficiency, but the contradiction between the reality of high coke ratio and high energy consumption in b...
