Abstract
The presence of non-metallic elements in steel and alloy
melts incorporate a number of effects, for which it is
necessary to control the multicomponent chemistry in
ladle processing as well as in casting. The non-metallic
elements appear either as processing elements (oxygen,
nitrogen) or they are deliberately added to the melt to
improve the final product quality (e.g. sulphur to
improve steel machinability). The formation of inclusions
in the melts is then a process, where these non-metallic
impurities will be reacting with various metallic
components of the melt. In steels, different oxide
nitride or sulphide based inclusions are characteristic.
