摘要: 
在世界各個國家中鋼鐵工業為國家最重要的基礎之一,而煉製鋼鐵的方式相當多種,例如:KR攪拌器、高爐、RH精煉爐......。在RH精煉爐為一高流場擾動與高溫環境的系統,上升管的鋼液因有高壓氬氣的帶動使得鋼液往上衝,下降管的鋼液則往下回流做一循環,在沖刷過程產生高剪應力對結構的強度產生影響,加上鋼液溫度高達1600℃造成的熱應力也對結構有著嚴重威脅,RH精煉爐的高溫環境且不容易進行實際觀察。根據RH精煉爐原始設計及部份改變設計,建構RH精煉爐三維模型,為以計算流體力學為基礎架構,經過流場模擬剪應力分析、熱應力分析,分別討論RH精煉爐經過不同設計下所得到的結果,進而改善RH精煉爐的使用壽命,以選擇出最佳化的RH精煉爐設計。

Steel industry is one of the country''s most important foundations in the world. There are many steel making method, for example, KR impeller, RH refining furnace. RH refining furnace is a high-flow disturbance and high temperature environment system, which the inlet port possesses high pressure liquid argon driven liquefied steel and the outlet port exits high-temperature liquefied steel to form a circulation. In the scouring process, high shear stress influences on the strength of RH refining furnace structure. In the mean time, thermal stress is caused by 1600℃ liquefied steel. RH refining furnace is high temperature environment and the phenomenon is not easy for the observation. According to RH refining furnace''s original design and various design of RH refining furnace, three-dimensional model of RH refining furnace is constructed, and the flow field simulation analysis thermal stress and shear stress was conducted by ANSYS. Based on the results of various RH refining furnace designs, the best design of the RH refining furnace is chosen to improve its life.
