Results obtained are summarized as follows : (1) Optimum moisture content necessary to balling decreased with the lowering of feeding speed and with the decrease in the size of fines.(2) The maximum of the compressive strength of green pellets was nearly in agreement with the maximum of apparent de nsity, corresponding to about 70% of the saturation of the void space between the particles with water.(3) It was recognized that the relation between the compressive strength of green pellets and the specific surface of fines measured by the permeability method was expressed by a straight line, and that the green pellets from magnetite fines and oxidized magnetite fines located on the same line except those from the mixture of very fines.(4) It was recognized from the microstructure of the thin sections of pellets that the compressive strength of dry pellets was dependent on the packing behaviour of fine particles.","subitem_description_type":"Abstract"}]},"item_4_description_41":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"紀要類(bulletin)","subitem_description_type":"Other"}]},"item_4_description_66":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"1038807 bytes","subitem_description_type":"Other"}]},"item_4_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"122851","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TAGUCHI, Noboru"}]},{"nameIdentifiers":[{"nameIdentifier":"122852","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OMORI, Yasuo"}]},{"nameIdentifiers":[{"nameIdentifier":"122853","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SANBONGI, Koji"}]}]},"item_4_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東北大學選鉱製錬研究所"}]},"item_4_radio_69":{"attribute_name":"公開範囲","attribute_value_mlt":[{"subitem_radio_item":"学外"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0040876X","subitem_source_identifier_type":"ISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00168425","subitem_source_identifier_type":"NCID"}]},"item_4_version_type_16":{"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":"田口, 昇"}],"nameIdentifiers":[{"nameIdentifier":"122848","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大森,  康男"}],"nameIdentifiers":[{"nameIdentifier":"122849","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"三本木,  貢治"}],"nameIdentifiers":[{"nameIdentifier":"122850","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000134795.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000134795.pdf","url":"https://tohoku.repo.nii.ac.jp/record/50326/files/KJ00000134795.pdf"},"version_id":"359b103c-4ea8-4fa3-95ae-7471cb1bfc7e"}]},"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":"<報文>鉄鉱石のペレタイジングに関する研究(第2報) : 磁鉄鉱のペレタイジング特性に関する基礎的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"<報文>鉄鉱石のペレタイジングに関する研究(第2報) : 磁鉄鉱のペレタイジング特性に関する基礎的研究"}]},"item_type_id":"4","owner":"3","path":["292"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-05-02"},"publish_date":"2008-05-02","publish_status":"0","recid":"50326","relation_version_is_last":true,"title":["<報文>鉄鉱石のペレタイジングに関する研究(第2報) : 磁鉄鉱のペレタイジング特性に関する基礎的研究"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T15:14:38.777772+00:00"}
