For addition I assume u are asking about the process during steelmaking. See first thing we need to note is that many elements like Si is already present in steel we can't get full rid of from the very first blast furnace process. Other than this we add some purposely for specific application and tyRead more

See first thing we need to note is that many elements like Si is already present in steel we can’t get full rid of from the very first blast furnace process. Other than this we add some purposely for specific application and type of steel we want. Now, I will explain the addition used in most general cases.
Sequence Mn, Si, Ti, B, Ca, Al Mn - To control S as MnS(preferred)than FeS(injuriou) in steel. Si - as Hypersil(4%) in turbine blades. Ti-B in composites, as substrate growth on W, Fe-B(protrusion), further purification will yield metallic glasses by rapid solidification. FeTi addition molten steel(Read more
Sequence Mn, Si, Ti, B, Ca, Al
Mn – To control S as MnS(preferred)than FeS(injuriou) in steel.
Si – as Hypersil(4%) in turbine blades.
Ti-B in composites, as substrate growth on W, Fe-B(protrusion), further purification will yield metallic glasses by rapid solidification. FeTi addition molten steel(how & why) to be used in space technology!
Ca as lime powder/CaC2 for dephosphorisation/to overcome C deficiency in molten steel.
Al is a powerful deoxidiser, used as Al blocks to promote/prevent directional solidification/piping while teeming molten steel.
