Fe-containing briquette including waste sodium bicarbonate, manufacturing method thereof and double slag process using the same

摘要

The present invention relates to 100 parts by weight of waste sodium bicarbonate generated in the desulfurization process of sintering flue gas, 800 to 2000 parts by weight of ironmaking by-products containing at least one of iron sludge and mill scale, and 40 to 100 parts by weight of a binder. It relates to an iron-containing briquette containing waste sodium bicarbonate, a manufacturing method thereof, and a converter double blowing method using the same, and recycles waste sodium bicarbonate generated after desulfurization of flue gas in a sintering plant of a steel mill, so waste that has been mainly relied on landfill Since sodium bicarbonate is used, it has an effect of contributing to the environment and has the advantage of more effectively removing phosphorus and sulfur contained in molten iron.
