How oxygen can be removed from steel during melting? What are fully killed steels ?

Description : How oxygen can be removed from steel during melting? What are fully killed steels ?

Last Answer : Oxygen can be removed by adding elements such as manganese, silicon or aluminium which, because of their high affinity for oxygen, react with it to form non-metallic oxides which rise into the slag. Steels which have had most of their dissolved oxygen removed are called “fully killed steels”.
