how to remove suphlur from iron ore

Sulphur in Steels ispatguru.Sep 23,2014 S in steel is introduced through iron ore and fuel (coal and coke).The removal of S during steel making is a tedious and difficult process.Get Price; Full text of The Chemistry of Iron and Steel. - Internet ArchiveVacuum Degassing of Steel Sulphur in Steels IspatGuru#0183;Tool steels are designated by a letter and a number in the AISI system,such as M2,which is a Molybdenum high-speed steel.Letters used denote either the principal alloying element which is varied to create different properties,the general kind of use the alloy is designed for,or how the alloy is to be heat treated.The Iron-Carbon Equilibrium Diagram : Total Materia ArticleSteels with less than about 0.8% carbon are thus hypo-eutectoid alloys with ferrite and pearlite as the prime constituents,the relative volume fractions being determined by the lever rule which states that as the carbon content is increased,the volume percentage of pearlite increases,until it is 100% at the eutectoid composition.
