抄録

The Tatara furnace, so called Nittoho Tatara, was reconstructed in 1977 based on "Yasukuni Tatara" which had been workedbefore the end ofthe World War II. Mr. Yoshizo Abe as a leader "Murage" developed the new techniques of direct steelmaking, "Kera-oshi" for Tatara operation only using "Masa" iron sand for the 3 stages of "Komori", "Nobori" and "Kudari". Until the age of "Yasukuni Tatara", the operation hadbeen carried out in 4 stages with "Komoritsugi" following "Komori", and in the first two stages, the "Komori" and "Komoritsugi" iron sandswith higher (Fe₂O₃)/(FeO) ratio had been used, respectively. In the presentwork, 7 Tatara operations with 3stages were carried out using"Komori" iron sand or "Masa" iron sand for the "Komori" stage followed by the last two stages using "Masa" iron sand.The operation using"Komori" iron sand produced more amountand higher carbon content of "Tamahagane" than that only using "Masa" iron sand, because "Komori" iron sand was reduced easier than"Masa" iron sand.
