iron making through oxy fuel process

Oxy-fuel welding and cutting - Wikipedial

Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the U.S.) and oxy-fuel cutting are processes that use fuel gases (or liquid fuels such as gasoline) and oxygen to weld or cut metals. French engineers Edmond Fouché and Charles Picard became the first to develop oxygen-acetylene welding in 1903.

Theory of Oxy-Fuel Gas Cutting | The Harris Products Groupl

Oxy-Fuel gas cutting is functional for use with low carbon and low alloy steels, with a carbon content generally restricted to 1/10 to 3/10 of 1%. The various alloy elements found in steel affect the ability of the oxygen to cut the metal. Elements such as manganese, silicon, phosphorus, and sulfur have very little effect in normally found levels.

Basic oxygen steelmaking - Wikipedial

Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.
