Before iron ore can be used, oxygen must be removed from it. Known as ‘reducing’, this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace. The blast furnace process also produces two

What is a Blast Furnace? | M. Brashem, Inc

A blast furnace uses heat to convert iron oxides into liquid iron, which can then be used for a variety of industrial appliions. The blast furnace is a brick-lined, stainless steel stack, which is heated using pre-heated air. Limestone, coke and iron ore are placed in

Increased Use of Natural Gas in Blast Furnace Iron-Making

Steelmaking is a highly carbon intensive process. Most of the CO2 emissions in steelmaking are from the blast furnace. Coke has been the major reductant used in a blast furnace since 1750. The recent boom in the US energy outputs due to shale rock formations has motivated the need to look at natural gas as a partial replacement for coke in a blast furnace. During the course of this project
