The History of Steel

Aug 21, 2020· Pig iron is molten iron run out of the blast furnaces and cooled in the main channel and adjoining molds. The large, central and adjoining smaller ingots resembled a sow and suckling piglets. Cast iron is strong but suffers from brittleness due to its carbon content, making it less than ideal for working and shaping.

Vanadium processing | Britannica

Vanadium processing, preparation of the metal for use in various products.. Vanadium (V) is a grayish silver metal whose crystal structure is a body-centred cubic (bcc) lattice, with a melting point of 1,926° C (3,499° F). The metal is used principally as an alloying addition to high-strength low-alloy (HSLA) steels and, to a lesser extent, in tool steels and iron and steel castings.

What Is Involved in Pig Iron Production? (with pictures)

Aug 08, 2020· Pig iron production is generally only one step in the creation of a finished iron product, since the high carbon content of iron in this form makes it mostly unusable. To make it more versatile, it can be melted again and mixed with slag, creating wrought iron, or combined with additional iron ore and alloys to create cast iron.
