Effect of physical properties of slag on sulphur

Each steel was remelted under three slag compositions with different physical and chemical properties. The results obtained showed the efficiency of ESR in removal of up to 68 % of the sulphur contained in the metal. This pronounced effect of ESR on desulphurization is a result of slag/metal and gas/slag reactions.
