Though archaeological excavations were conducted on O-kaji sites, the accession of the process had end and the technical detail was recorded in only two research papers.\nWe constructed experimental furnaces of o-kaji and operated them under various conditions to prospect the details of the technology and situation of the reaction in the furnace. As the result, we succeeded at reappearance of O-kaji, even in a smaller-scale, by using pig iron made with the modern tatara-smelting process operated by The Society for Preservation of Japanese Art Swords.\nWe supposed the basic reaction mechanism of o-kaji as follows;\n1. The temperature of preheating was about 800℃ , at which decarburized layer was not produced at the surface. After the whole material pig iron was heated enough, the temperature was rapidly risen to around 1150℃ , at which the inside-wall of pig iron started to melt.\n2. With the wind from tuyere, the air pressure under the arch-like pig iron reduced. Then carbon monoxide was drawn into there with air from gap between the pig-iron and the furnace wall. They burned under the empty space under the pig-iron and heated the inside-wall.\n3. Decarburizing was processed with taking a certain amount of time at the bottom of furnace with being blown by the wind from furnace after melted pig iron dripped. So the melting should proceed in small steps otherwise decarburizing did not make progress inside of the massive melted pig iron. Fine control should be needed to keep the adequate temperature of inside-wall for successive process of little by little melting, drip and decarburizing.","subitem_description_type":"Abstract"}]},"item_10002_heading_23":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"歴史資料に対する自然科学的調査法の開発と適用に関する研究","subitem_heading_language":"ja"},{"subitem_heading_banner_headline":"Research on the Development and Application of Natural Science Methods of Analyzing Historical Materials","subitem_heading_language":"en"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15024/00000226","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立歴史民俗博物館","subitem_publisher_language":"ja"}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"第177集 収録論文 タイトルリスト"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.rekihaku.ac.jp/outline/publication/ronbun/ronbun8/index.html#no177","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00377607","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-7400","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"齋藤,  努","creatorNameLang":"ja"},{"creatorName":"サイトウ, ツトム","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"坂本,  稔","creatorNameLang":"ja"},{"creatorName":"サカモト, ミノル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高塚,  秀治","creatorNameLang":"ja"},{"creatorName":"タカツカ, ヒデハル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Saito,  Tsutomu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sakamoto,  Minoru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takatsuka,  Hideharu","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-04-01"}],"displaytype":"detail","filename":"kenkyuhokoku_177_06.pdf","filesize":[{"value":"3.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kenkyuhokoku_177_06","url":"https://rekihaku.repo.nii.ac.jp/record/242/files/kenkyuhokoku_177_06.pdf"},"version_id":"09e68ff3-e171-4b4e-9e07-f3e4e2308e47"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"銑鉄","subitem_subject_scheme":"Other"},{"subitem_subject":"脱炭","subitem_subject_scheme":"Other"},{"subitem_subject":"軟鉄","subitem_subject_scheme":"Other"},{"subitem_subject":"前近代技術","subitem_subject_scheme":"Other"},{"subitem_subject":"精錬","subitem_subject_scheme":"Other"},{"subitem_subject":"pig-iron","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"decarburizing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"wrought iron","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"pre-modern technology","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"refining","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"大鍛冶の炉内反応に関する検証と実験的再現","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"大鍛冶の炉内反応に関する検証と実験的再現","subitem_title_language":"ja"},{"subitem_title":"Experimental Inspection and Reconstruction of Ookaji, a Pre-modern Process of Pig Iron Decarburizing","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"3","path":["22"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-01-04"},"publish_date":"2016-01-04","publish_status":"0","recid":"242","relation_version_is_last":true,"title":["大鍛冶の炉内反応に関する検証と実験的再現"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-14T06:11:36.194767+00:00"}
