Steel strip for cans

  Cleanness/consistency     6 of 8
 

The cleanness of a steel relates to the number of inclusions / large particles present in the material. Before considering the detailed origins of inclusions, the factors controlling their nature and incidence, and the techniques used by the modern steelmaker to manipulate the inclusion population (inclusion engineering), it is first useful to define a number of key terms and outline the importance of inclusions in steelmaking. Click on any of the following sentences to find out more.

Dependent on the steel type being manufactured, its processing conditions and final application, inclusions with different chemistries, morphologies and deformation characteristics are desirable.

We have seen that some inclusions are present due to the chemistry of the steel (indigenous inclusions, for example 'inclusions for improved machinability').

To review where exogenous (external to the system) inclusions can originate from we need to analyse the components of the ladle steelmaking system.)
