Process for the production of pig iron in the blast furnace and blast furnace for the production of pig iron by melting and by reduction of aufzuschmelzendem and to be reduced material

摘要

The invention relates to a method for the production of pig iron in the blast furnace, wherein the supply of fuels such as coke, coal dust or the like, the melted and reduced material, such as iron ore, iron oxides, iron pellets, sinter or the like, is melted and reduced. In order to provide a method by which the amount of coke per tonne of pig iron produced can be reduced, should be fed into the blast furnace, in particular in the lower region, a mixture containing either air and / or oxygen on the one hand and water in the form of Water vapor or atomized water (mist) comprises or consists solely of one hand, air and / or oxygen and on the other hand of water in the form of water vapor or atomized water (mist). The invention also relates to a blast furnace for the production of pig iron by melting and by reduction of aufzuschmelzendem and reducing material such as iron ore, iron oxide, iron pellets, sinter or the like, with the supply of fuels such as coke, coal dust or the like.
