Bessemer process | metallurgy |

Bessemer process: Bessemer process,, the first method discovered for mass-producing steel. Though named after Sir Henry Bessemer of England, the process evolved from the contributions of many investigators before it could be used on a broad commercial basis.

How iron is made - material, manufacture, making, history ...

Historically, iron was produced by the hot-blast method, or later, the anthracite furnace. Either way, the fundamental activity in iron making involved a worker stirring small batches of pig iron and cinder until the iron separated from the slag.

Iron ore - Wikipedia

The Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities.

Steel - Chemistry Encyclopedia - structure, elements, metal ...

Steel is an alloy of iron with about 1 percent carbon. It may also contain other elements, such as manganese. Whereas pure iron is a relatively soft metal that rusts easily, steel can be hard, tough, and corrosion-resistant.

Mike Fitzpatrick explains how first cast iron and then steel were developed, and the vital part these discoveries played in the industrial revolution.

How is Steel Produced? | World Coal Association

Global steel production is dependent on coal. 74% of the steel produced today uses coal. Metallurgical coal – or coking coal – is a vital ingredient in the steel making process.

Midrex Process for Direct Reduction of Iron Ore |

Midrex Process for Direct Reduction of Iron Ore. Midrex is an ironmaking process, developed for the production of direct reduced iron (DRI). It is a gas-based shaft furnace process is a solid state reduction process which reduces iron ore pellets or lump ore into DRI without their melting using reducing gas generally formed from natural gas.

How steel pipe is made - material, manufacture, making ...

Steel pipes are long, hollow tubes that are used for a variety of purposes. They are produced by two distinct methods which result in either a welded or seamless pipe. In both methods, raw steel is first cast into a more workable starting form. It is then made into a pipe by stretching the steel out ...

Metal Profile: Iron Properties and Characteristics - The Balance

Iron's use by humans dates back about 5000 years. It is the second most abundant metal element in the earth's crust and is primarily used to produce steel, one of the most important structural materials in the world. Pure iron is a silver-colored metal that conducts heat and electricity well. Iron ...

Steel - Wikipedia

When iron is smelted from its ore, it contains more carbon than is desirable. To become steel, it must be reprocessed to reduce the carbon to the correct amount, at which point other elements can be added.

Iron processing |
