Blast Furnace Process

The iron blast furnace is a tall, vertical shaft furnace which uses carbon, mainly in the form of coke to reduce iron ores. The product, a hot metal (which is impure iron), is suitable as feed material for steelmaking to refine it. A schematic view of a typical blast furnace plant is shown in Fig. 2.1.

Blast Furnace Process

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.

Blast Furnace and its Design

The ratio of total furnace height to belly diameter for mid and large size blast furnaces decreases from around 3 to 2.00 as the furnace useful volume increases from 1000 cum to 5500 cum. The ratio of furnace belly diameter to furnace hearth diameter varies in the range of 1.09 to 1.13 ( ideally it should be 1.05 to 1.10) .
