STUDIES ON THE SINTERING MECHANISM OF IRON ORE PELLET (II)

Abstract

In continuation to the previous research (Tetsu-to-Hagané, vol, 43, No. 5 1957, p. 619) the phenomena of sintering process of iron oxide pellet was investigated by use of new apparatus. And some kinetic considerátions were made on the sintering process and it was found that the W. Jander's equation on solid reaction,
F=(1-3√1-x)(2)
esactly had conformed to the experimental data.
Deducting from these experiments and considerations, the authors distinguished the sintering process into two parts: i.e. the former was "film sintering" and the latter was "body sintering" at higher temperature, and much care should be paid to the former stage of practical pelletizing operations.
