Verfahren zur Erzeugung von Roheisen

摘要

The invention relates to a method for producing pig iron using blast furnaces or other appropriate devices, in which materials containing iron are reduced and smelted in the presence of fuels. According to the invention, metallurgical coke can be converted into reduction gas and coke using economical organic exchange gases by combining a multistep process for exchange fuel gasification and a blast furnace process, into which the products of the gasification process are fed together or separately at the height of the mouth of the tuyere or through the latter into a melt. The gasification process is also used in the prereduction of iron oxides, fine ores and ore concentrates.
