An Efficient process for Desulphurization of Ferrous Melts

Chakrabarti, D J (1981) An Efficient process for Desulphurization of Ferrous Melts. In: Proceedings of International Symposium on Modern Developments in Steelmaking, 1981, NML, Jamshedpur.



The paper describes a desulphurization process developed at the NML which offers high degree of desulphurization efficiency on both hot metal and steel. Results from the laboratory experiments presented in the paper show that it is possible to reduce sulphur from the normal hot metal levels of 0.05% to 0.09% down to less than 0.01%, by employing agents amounting to 1.2% to 1.5% of the metal weight. Unlike the other presetly popular desulphurizing agent, such as CAC2 or Mg base materials, the present process is less susceptible to upward trend in raw material cost and also does not suffer from pollution hasarde inherent in soda ash or Cac2 treatment. The process is based on desu-lphurisation by Mg vapour, formed in-situ from its comp-ounds under the conditions of the molten bath.
