How to Make Steel: Blast Furnace Vs. Electric Arc Furnace
A typical blast furnace used by a traditional, extractive steel mill. The integrated steelmaking process, also known as extractive steelmaking, is the traditional method for producing steel. It starts with mining raw materials out of the ground, including iron ore, limestone and coal.
Steel Production - American Iron and Steel Institute
How Steel Is Made. Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day.

Blast furnace - Wikipedia
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being supplied above atmospheric pressure. [1]
EAFvsBlastFurnace - Steel Dynamics
Using EAF steelmaking technology, we generate approximately a third of the GHG emissions per metric ton compared to those generated from global blast furnace steelmaking technology, which creates significant emissions through the conversion of iron ore, coke, and coal into steel.¹
Blast Furnace Process - Steel Museum
A blast furnace is a steel cylinder lined with refractory. It operates continuously until the lining wears out, which takes many years to occur. The term blast furnace comes from the blast of hot air that is blown into the lower part of the furnace at between 1400º to 2100ºF. Molten iron is produced in a blast furnace by the following steps: 1.

Making Steel Blast furnace. 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.
Nippon Steel Corporation is operating 13 blast furnaces (BFs), seven of which are large BFs having an inner volume exceeding 5000 m 3 . Various plant engineering technologies
Blast Furnace - an overview | ScienceDirect Topics
Blast furnace gas is produced from the blast furnace in a steel mill. This gas has 23% of carbon monoxide, 60% of nitrogen, and 14% of carbon dioxide. The heating value is low.
