Refining of Indian Pig iron in an Experimental L-D Oxygen Converter(II)

THE growing acceptance of various oxygen steel
making processes ,with their merits, and demerits
including theoretical aspects and metallurgical
reactions involved has been thoroughly discussed
in the first part of the paper by Sen, Nijhawan
and Chatterjea.. In this paper the economic cons-
ideration and cost comparison of L-D process with
other conventional basic steel marking processes,
namely, the Open-Hearth and Thomas process as
Well as reasonings and justification of adopting
L-D process in future steel expansion programme
in India will he discussed.
