Iron-Carbon Phase Diagram Explained [with …

Both steel and cast iron are a mix of iron and carbon. Also, both alloys contain a small amount of trace elements. The graph is quite complex but since we are limiting our exploration to Fe3C, we will only be focusing up to 6.67 weight percent of carbon. This iron carbon phase diagram is plotted with the carbon concentrations by weight on the X

How we make steel | British Steel

Making steel. At Scunthorpe, we use the Basic Oxygen Steelmaking (BOS) process – our modern convertors (or vessels) take a coined charge of scrap and liquid iron of up to 330 tonnes and convert this into steel in just 25 minutes. When the liquid iron arrives at the BOS Plant, it’s poured from the torpedoes into refractory-lined charging

Evraz Highveld Steel: Process Overview

Process Overview. Evraz Highveld’s iron and steel works annually produces around one million tons of steel blocks. Of this 40% is used to manufacture structural sections, engineering rounds and rails and 45% to manufacture plates and coiled plates and sheets. Some 15% of the steel produced is used to cast billets to be sold for re-rolling.

Creating Steel | HowSfWorks

Another way to create steel from pig iron is the Bessemer process, which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer converter.The heat of oxidation raises the temperature and keeps the iron molten. As the air passes through the molten pig iron, impurities unite with the oxygen to form oxides.

Iron Ore Smelting Process - Bright Hub …

The pig iron can be further refined to produce steel or wrought iron. Both these methods reduce the carbon content of the pig iron, which in turn reduces the brittleness property of the metals. Wrought Iron Process. Wrought iron is produced by pummeling the pig iron using mechanically driven hammers in a wrought iron works.
