製鉄用硫酸滓の基礎的研究(II)

抄録

There are two kinds of cinders, obtained as the residue in sulphuric acid plant. One is mainly composed of Fe₂O₃ (Pyrite cinder Py-C) and the other is mainly composed of Fe₃O₄
(Pyrrhotite cinder Pr-C).
To clarify differences of the reducing behavior between these two cidners.
The cinders were investigated as follows:
(1) Measurement of high temperature permeability at various temperature.
(2) Degree of reducibility.
The main results were as follows:
(1) Py-c was reduced easier than Pr-c by CO and solid C.
(2) High temperature permeability of Py-c was better than that of Pr-c.
