Blast Furnace Process 2 The objective of the blast furnace (BF) is to produce hot metal. The blast furnace is a tall, vertical shaft furnace which uses coke to reduce iron ores. The product, a hot metal (which is impure iron), is suitable as feed material for steelmaking. There are different charging systems for BF discussed in detail.

826· The blast furnace was where the smelting process was started. NPS Photo / Elizabeth Thakkar In 1646, the original blast furnace roared to life, lit with a 3000 degree fire that was kept burning 24 hours a day for months at a time. The blast furnace is where bog ore was smelted to create cast iron "pig" bars, so named because liquid cast iron was fed from a larger …

11· The integrated iron and steelmaking route involves blast furnace (BF) ironmaking followed by basic oxygen furnace (BOF) steelmaking. The BF uses sinter, pellets, and lump ore as iron-bearing raw materials, and coke and pulverized coal as fuel and reducing agents to produce hot metal with consistent quality for the BOF process. It produces approximately 68% …

Crushing As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size. Crushed ore is divided into various fractions by passing it over sieves through …
