Steps in the Modern Steelmaking Process

Jan 14, 20200183;32;Primary steelmaking has two methods BOS (Basic Oxygen Furnace) and the more modern EAF (Electric Arc Furnace) methods. The BOS method adds recycled scrap steel to the molten iron in a converter. At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 01.5%.

Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted. Iron ore mining is classified into two categories manual mining and mechanized mining methods. Haematite and magnetite are the most commonly found iron ore minerals. Deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from the

Metal Casting Methods Life of a Casting Reliance Foundry

Most iron and steel objects are made through expendable casting processes. Using molds to reproduce objects is a very common process in manufacturing, and low temperature molding substances (resins, chocolate, wax, etc.) almost always use reusable molds. What makes metallurgy different is the high temperatures involved.

Owing to environmental concerns, alternative methods of processing iron have been developed. quot;Direct iron reductionquot; reduces iron ore to a ferrous lump called quot;spongequot; iron or quot;directquot; iron that is suitable for steelmaking. Two main reactions comprise the direct reduction process Natural gas is partially oxidized (with heat and a catalyst)

How Is Cast Iron Made? Sciencing

Apr 24, 20170183;32;Casting is the process of pouring the iron into a mold thus giving it a shape. Molds and pouring methods divide this process up. Molds can be made as expendable molds (sand) or nonexpendable molds (metal). Pouring can happen via gravity, lowpressure or vacuum. Controlling the pouring process becomes more important the more intricate the mold is.

The Making of Iron amp; Steel SEAISI

Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as quot;ganguequot;. The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.

How is Iron Refined from Ore? (with pictures)

Mar 21, 20200183;32;Although iron does not occur in its pure form in nature, some kinds of ore contain up to 70% iron atoms. Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process.
