<p> The dominant slag-metal reaction site in AC electro-slag
remelting (ESR) has been directly determined by estimating the rate of
sulphur transfer at the electrode tip/slag and metal pool/slag interfaces.
In this investigation, negligible sulphur transfer has been
assumed at the droplet/slag interface, and the basis for such assumption
is discussed. Using a 5.825" diameter mould and CaF2-CaO slags,
it has been established that the electrode tip/slag interface is the
dominant reaction site. Calculations indicate that the pool sulphur
is close to equilibrium with the slag. The importance of all six
reaction sites in AC ESR are discussed. The results indicate the
importance of the slag/atmosphere interface, especially when using slags
of low lime content. Conventonal overall sulphur balances have
been carried out and the results are in agreement with the rates
obtained at the different interfaces, thus indicating internal consistency
of the results. </p> / Thesis / Master of Engineering (MEngr)
