SYNOPSIS: -To clarify the social background and the technical foundations of “New Iron-making Processes” which have become current topics, a short history of the development of “Iron-making Processes without help of Blast Furnace” was traced and the attainments of the progress of these processes in the 1960's were summerized. Specially with regard to electric steelmaking process from reduced pellets as well as so-called iron-making plans with use of atomic energy, an outline of their aims and contents was given. Finally it was pointed out that the most urgent problem for Japanese Steel Industry was not to replace the existing process with “New Process”, but to improve the former still more, that is to say, to decrease coke (or coking-coal)-consumption in blast furnace operation as much as possible.
