The element iron (Fe) is one of the most abundant on earth, but it does not occur in nature in useful metallic form. Iron ore is the term applied to a natural iron-bearing mineral in which the content of iron is sufficient to be commercially usable. Metallic iron, from which steel is derived, must be extracted from iron ore. By definition, steel is a combination of iron

The iron and steel industry, including primary and secondary producer s, is composed of 79 companie s that produce raw steel at 116 locations. Iron is generally produced from iron ore (t aconite) in a primary mineral production process, while steel is produced using both primary and secondary processes. Primary production refers

The production of steel in an EAF is a batch process. Cycles, or "heats", range from about 1-1/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrap steel is charged to begin a cycle, and alloying agents and slag materials are added for refining. Stages

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.

Cast Iron Pipe was the original metal pipe used for most urban water main construction throughout the 20th century until the 1970s. Cast iron can still be found in the older sections of urban water distribution systems. It was relatively easy to manufacture and install. However, it is very brittle, making it prone to cracking and structural ...

Ductile iron pipe is pipe made of ductile cast iron commonly used for potable water transmission and distribution. This type of pipe is a direct development of earlier cast iron pipe, which it has superseded. The ductile iron used to manufacture the pipe is characterized by the spheroidal or nodular nature of the graphite within the iron
