Abstract
The present Paper refers to the fundamental research in manufacturing sponge iron from iron ore in Manchukuo.
The experiments were made under abont 1, 000°C. using a small fixed tube furnace, rotary furnace and semi-industrial rotary kiln with respect to the following problems:-
1) Size and form of ore
2) Preliminary roasting of ore
3) Nature of reducing gases
4) Quantity of gas flow
5) Temperature of reducing ore
6) Effect of catalytic reagents
From the results obtained, some new conceptions regarding to the manufacture sponge iron in an industrial scale are explained.
