摘要: 鑄軋區(qū)金屬(液態(tài)金屬、粘糊狀金屬和冷凝殼)的流動為非均勻介質(zhì)流動。在鑄軋區(qū)溫度場分析的基礎(chǔ)上，推導(dǎo)了非均勻介質(zhì)流動流函數(shù)控制微分方程，用有限元法求解該方程。給出了太原鋁廠雙輥傾斜式鑄軋機(jī)在穩(wěn)定生產(chǎn)條件下鑄軋區(qū)金屬的凝固傳熱和流動規(guī)律。

Abstract:The flow of metal in castrolling area (liquid metal, sticky metal and solid shell) is an uneven medium flow. By analyzing the temperature field in castrolling part, the controlled differential equation of the flow function for an uneven medium flow was studied, and the equation was extracted with FEM. In a steady production of the twinroller aluminum castrolling machine in Taiyuan Aluminum Plant, the solidification transmit heat and the flow of metal in castrolling part were analyzed.

Key words: flow function; continuous castrolling; FEM
