Metal Melt & Pour: Life of a Casting

The true Iron Age started, however, when people figured out how to extract useful iron from ores, and that requires melting to soft, taffy-like, near-liquid, or liquid states. This advance came to different parts of the globe at different times but involved the invention of bloomery furnaces and a slow building of the knowledge of ferrous metallurgy.

CPC

 · Until the s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration.

Iron Ore

Iron ores are rocks from which metallic iron can be economically extracted. These rocks are usually found in the form of hematite (Fe2O3) or magnetite (Fe3O4). About 98% of world iron ore production is used to make iron in the form of steel. Nearly all of Earth's major iron ore deposits are in rocks that formed over 1.8 billion years ago.

ABOUT STEEL

A total of 70.7% of steel is produced using the BF-BOF route. First, iron ores are reduced to iron, also called hot metal or pig iron. Then the iron is converted to steel in the BOF. After casting and rolling, the steel is delivered as coil, plate, sections or bars.

Metallurgical Materials Science and Alloy Design

The current annual consumption of iron ores for this process amounts to a gigantic 2.6 billion tons, producing about 1.28 billion tons of pig iron through this route. Each ton of steel produced by this conventional primary synthesis, i.e. through a blast furnace followed by a basic oxygen converter, creates about 2.1 tons of CO2.
