Rapporteur's Summary

Abstract

I shall try to summarise six papers within the time that has been alloted to me. Two of them are on electric arc furnaces-one by W.Maschlanka of Korf Stahl AG, and another by G.Meyer, R.Baum and R.Heinke of Krupp-Industrie and Stahlbau, both from West Germany. These papers discuss the modern developments in both the operational and design aspects of electric arc steelmaking furnaces and some of them are very pertinent to Indian conditions as we are looking forward to electric arc furnaces to make signi-ficant contributions to steel production at least through the mini-steel plants. Two more papers are from leading steel producers in India giving their experiences with electric steel-making for the last several years and the programmers that they have evolved for the future course of growth. One is by A.K. Hazra, S.K. Bhattacharya and J. Banerjee of Alloy Steel Plant, Durgapur and the other by S. Soundararajan and K.B. Kale of Mukand Iron and Steel Works Ltd., Bombay. In addition there is an interesting paper by G.Marizy of Ugine Aciers, France reviewing recent developments in stainless making. The paper by V.M. Tarassov, S.Jha Ajit, R.S. Shrotriya and S. Narayan is on a very interesting process from the point of view of India, (especially since we have a lot of open-hearth furnaces which we cannot afford to replace immediately), namely the twin hearth furnace, which can be easily constructed by modifying the existing open hearth furnaces to give nearly three- fold increase in production. I will present these papers in that order.
