Example Embodiment
[0025] Example 1
[0026] Before the experiment, the coke consumed by the blast furnace was bulk coke with a particle size of ≥25mm and coke with a particle size of 10-25mm. The coke with a particle size of 10-25mm was mixed with iron ore. During the experiment, 2 circles of 5-10mm small coke were placed on the edge of the furnace throat instead of large coke. At the beginning, 2 circles of coke were placed on the edge of the blast furnace for every 5 batches, and the proportion of small coke was gradually increased. When the furnace condition became stable, At the same time, each batch of material is clothed with 2 circles of small scallops on the edge. Loading system by tweak to (Where K stands for ore, J d And J s Respectively represent large coke and small coke with a particle size of 5-10mm, and the superscript and subscripts of the numbers represent the unit and the number of cloth circles respectively). The monthly economic and technical indicators before and after the...
