项目摘要

In the research carried out in three fiscal years from 2003 to 2005, I clarified experimentally characteristics of technique on iron-making and blacksmithing in late stage of Kofun period.The result is as follows ;1.The bed of iron smelting furnace was not made of charcoal but clay in Chuugoku mountainous district. Product of the furnace is pig iron.2.In the north half region of Kyushu, iron smelting furnace, which is different from the furnace in Chuugoku mountainous district, is supposed to have been producted pig iron.3.Because products by these furnaces contained high carbon, it was needed to have been reduced carbon before smithing. Furnace for the refining already appered in the latter half of the fifth century.4.There is a big difference in structure of iron smelting furnace between in Chuugoku mountainous district and in a Korean peninsula. It is supposed that the former furnace was originated in the furnace for smithing (or refining) in Japan.Moreover, on the result of a prior investigation of iron smelting furnace and furnace for smithing (or refining) in South Korea, experiments of smelting and refining were conducted.The result is as follows ;5.Korean smelting furnace, differing in structure from one in Kofun period, can also product pdg iron.6.Furnace for refining, different from the furnace of Kofun period, can reduce carbon from pig iron.Through these points of view, I could clarify technique for smelting and refining iron in Kofun period in Japan and in Sam'an-Samguk period in Korean peninsula. Moreover, a technological difference of Japan-South Korea was able to be interpretable, and to have obtained an important finding for the technology exchange concerning iron.

在2003 ~ 2005年的三个财政年度的研究中，笔者通过实验阐明了古坟时代晚期炼铁和锻造技术的特点，结果如下：1.中国山区炼铁炉的炉床不是木炭，而是粘土。2.九州北半部地区的炼铁炉与中国山区的炼铁炉不同，应该是生产生铁的; 3.由于这些炼铁炉的产品含碳量较高，所以在锻造前需要进行还原碳处理。5世纪后半叶，已经出现了用于冶炼的熔炉。4.中国山区的炼铁炉与朝鲜半岛的炼铁炉在结构上有很大的不同。据推测，前炉起源于锻造炉此外，根据对日本的炼铁炉和锻造炉的调查结果，在韩国进行了冶炼和精炼试验，结果表明：5.韩国的冶炼炉，与古坟时期的熔炉不同，也可以生产pdg铁。6.精炼用的熔炉，与古坟时期的熔炉不同，通过这些观点，可以阐明日本古坟时期和朝鲜半岛三安三国时期的炼铁和炼铁技术。此外，日本和韩国的技术差异是可以解释的，并获得了有关铁的技术交流的重要发现。
