As a countermeasure, a coating is applied to the mold. However, coating is often done with experience and intuition. In this study, the effects of casting conditions and mold coating were investigated on the fluidity of AC4C aluminum alloy. As a result, it was found that the higher the casting temperature and the mold temperature, the longer the flow length. And that by applying the mold coating, the flow length becomes significantly longer and the casting surface defects were reduced. Also, the heat transfer coefficients between the molten metal and the metal mold were measured, the heat transfer coefficients ware reduced to about 1/5 by applying the coating mold. In addition, CAE analysis using the obtained heat transfer coefficient confirmed that the measured flow length and the analyzed flow length were almost the same.", "subitem_description_type": "Abstract"}]}, "item_10002_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2185-3746", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "佐藤, 裕樹"}, {"creatorName": "サトウ, ユウキ", "creatorNameLang": "ja-Kana"}], "nameIdentifiers": [{"nameIdentifier": "712", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "西, 直美"}, {"creatorName": "ニシ, ナオミ", "creatorNameLang": "ja-Kana"}], "nameIdentifiers": [{"nameIdentifier": "713", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "SATO, Yuki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "723", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "NISHI, Naomi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "724", "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": "2022-02-08"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "bulletin_168.pdf", "filesize": [{"value": "939.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_11", "mimetype": "application/pdf", "size": 939300.0, "url": {"label": "AC4Cアルミニウム合金の湯流れ性に及ぼす鋳造条件及び塗型の影響", "url": "https://iot.repo.nii.ac.jp/record/254/files/bulletin_168.pdf"}, "version_id": "2d30ea4d-3c67-4209-86c8-c1080178b6d8"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "アルミニウム合金", "subitem_subject_scheme": "Other"}, {"subitem_subject": "金型鋳造", "subitem_subject_scheme": "Other"}, {"subitem_subject": "熱伝達係数", "subitem_subject_scheme": "Other"}, {"subitem_subject": "流動性試験", "subitem_subject_scheme": "Other"}, {"subitem_subject": "塗型", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Aluminum alloy", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Permanent mold casting", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "heat transfer coefficient", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "fluidity test", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "mold coating", "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": "AC4Cアルミニウム合金の湯流れ性に及ぼす鋳造条件及び塗型の影響", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "AC4Cアルミニウム合金の湯流れ性に及ぼす鋳造条件及び塗型の影響"}, {"subitem_title": "Effects of casting conditions and coating on the fluidity of AC4C Aluminum alloy", "subitem_title_language": "en"}]}, "item_type_id": "10002", "owner": "11", "path": ["20"], "permalink_uri": "https://iot.repo.nii.ac.jp/records/254", "pubdate": {"attribute_name": "公開日", "attribute_value": "2022-02-08"}, "publish_date": "2022-02-08", "publish_status": "0", "recid": "254", "relation": {}, "relation_version_is_last": true, "title": ["AC4Cアルミニウム合金の湯流れ性に及ぼす鋳造条件及び塗型の影響"], "weko_shared_id": -1}
