On the Bottom Blown Processes and the LD-AC Process

Abstract

In February 1957, we had an opportunity to speak,in this country, in New Delhi, about the results of the research carried out by our centre National de Recherches Metall-urgiques in the feild of steelmaking; to be more precise, in the feild of blowing iron in a basic bottom-blown converter either with oxygen-enriched air or with an ox-ygen and steam mixture. On that occasion, we also emphasised the results dea- ling with the industrial development of the new blowing processes that we formerly recomended. From that time the industrial application of these methods still expanded and at the present time 10 steelworks have recourse to it. Let us point out the fact that two out of these works are located in Great-Britain and that a third steelworks will start running there within a few months.
