Steel - Simple English Wikipedia, the free encyclopedia

Steel is iron mixed with carbon and perhaps other metals. It is harder and stronger than iron. Iron with more than 1.7% percent carbon by weight is named cast iron. Steel is different from wrought iron, which has little or no carbon.

Tata Steel''s Sustainable Steel Making Process

Tata Steel has undertaken extensive research in making the process of steelmaking more energy-efficient and environmentally sustainable. From coarse and rocky iron ore to tough and shiny steel - the making of the alloy is a journey that starts from the crust of the earth, involves complex metallurgical reactions and processes, and demands technological expertise of the highest degree.

Glossary of Metal Industry Terms - Reade

Alloys change the properties of the steel making it, for example, harder, more formable, etc., depending on the coination and amounts of alloys used. Annealing: The process by which steel is heated and then cooled to improve its formability and make its surface more durable.

How is Steel Made? – Official POSCO Newsroom

The process of solidifying iron and coal is called sintering and coking, respectively. The pretreated iron and coal are stacked into layers in a 100m tall blast furnace. Then hot air at 1,200 degrees Celsius is blown into the furnace, causing the coal to burn which melts iron ore into molten iron.

KR Hot Metal Desulfurization System | Steel Plantech

This process of removing impurities from molten metal in advance before charging it into a converter furnace is called hot metal preliminary processing. The KR Hot Metal Desulfurization System developed by Steel Plantech will achieve high-level desulfurization efficiency as well as contribute to a …

What is steel made out of and why - Answers

Steel is a metal alloy consisting of iron and carbon and is currently produced in commercial quantities through a process called basic oxygen steelmaking. The carbon content of steels usually

Manufacturing Process - Sheet Metal Bending

In a process called wiring, the metal''s edge is bent over a wire. How the bead is formed will depend on the specific requirements of the manufacturing process and sheet metal part. Figure:275 Hemming is an edge bending process in which the edge of the

Steel mill - Wikipedia

During the casting process various methods are used, such as addition of aluminum, so that impurities in the steel float to the surface where they can be cut off the finished bloom. Because of the energy cost and structural stress associated with heating and cooling a blast furnace, typically these primary steel making vessels will operate on a continuous production campaign of several years
