抄録

An extension of the previous study on the correlation analysis of the practical operation data of the shaft furnace for Ni smelting was carried out.<BR>The respective and dual influences of coke weight per day (C) and ore weight per day (O) on Rr, that is (Fe weight in matte)/(FeO weight in slag), were investigated and the results obtained were as follows:<BR>(1) Rr=5.3 (C/O-0.20).<BR>(2) Rr=-0.001 (0-1110) at C/O=const.<BR>(3) Rr had some correlations with C and O of the day before that day as well as those of the day on which Rr was measured.<BR>Thus C/O played a role in Ni smelting operation to determine Rr, which was directly concerned with the yield of Ni.<BR>The most desirable value of C/O with the shaft furnace for the maximum profit were determined with the following formulae obtained from the above relations:<BR>C/O=1/100√P1·Ni0%/P3+0.19<BR>C/O=√1/100·P2/P2·Ni0%+0.002+0.20where P1: Price of Ni in matte per ton<BR>P2: Price of Ni in ore per one per cent, per ton<BR>P3: Price of coke per ton<BR>Nio%: Ni per cent in ore<BR>J.
