Desulphurisation of hot metal through generation of magnesium vapour inside the metal bath

What is it about?

Use of magnesium powder or ribbon for the desulphurisation of liquid iron is uneconomical since it involves the production of the metal using energy, then cooling it to ingots, which entails a loss in the process. In situ generation of magnesium uses the sensible heat in the hot metal for producing magnesium vapour directly inside the bath, for desulphurisation. There is no loss of metal. This proces sis more economical compare dto teh conventional desulphurisation process.

Why is it important?

This process will considerably reduce the cost of desulphurisation. The device developed can be used for injecting magnesium vapour into liquid iron bath for producing iron-magnesium alloys, also.
