| 中文摘要 | 本研究利用不同成份的濕模砂,造模成單獨流路系統後,澆鑄熔融鐵水,並在流路出口處上取冷激片,作化學成份分析,全面探討鑄鐵鐵水成份變化、澆鑄時間、溫降、砂模成份變化等,對熔融鐵水與濕模砂在流路反應前後的鐵水化學成份變化。實驗結果顯示,砂模與鐵水接觸反應後,鐵水的成份會產生變化;鐵水成份變化與反應氣氛會影響濕模沙鑄件表面品質。綜合實驗的資料,有助於瞭解各種鑄件作表面品質的關係和成因,提供給工業界做參考。 |
| 英文摘要 | This study fully investigates the effect of filling time, pouring temperature, and chemical composition of molten iron in different sand molds of moisture on the constituent changes of silicon and carbon in the runners. Variables concerned are temperatures of molten iron, ingredients of green sand and its mulling effect, different filling time in the runners. Green sand will be prepared in the range of bentonite (6-10%), seacoal (2%) and recycled dust (6.2% max.). Microstructures and surface qualities also observed from the effect of changes of chemical composition during filling. Under the effect of above-mentioned variables, experimental data can show the ingredients changes of silicon and carbon before and after the runners, surface qualities of casting when dynamic sampling atmosphere during filling. All these data will be treated as reference base for comparing the surface qualities of castings and carbon equivalent loss from the pouring trials. |
