ABSTRACT |
Chemical analysis and metallographic observations of the iron slag were carried out in an attempt to estimate the old iron-making process. The slag containing without Cu indicates that the ore used for smelting was sand iron, not rock ore. The phases identified in the slag were , magnetite, , fayalite etc. This also supports the fact that the smelted ore was iron sand. The total amount of Fe and slag-making components were , respectively. These values were average ones found in the old slags formed in the ancient iron-making process. Assuming that in the ore combines with FeO, resulting in the formation of , the estimated temperature of smelting was found to be about . |
