摘要


本研究之目的,在建立冷軋製程中使用乳液為潤滑劑之混合潤滑模式,在 冷軋過程中其乳液油膜之形成,採用Schmid所發展的動態集中模式。在大 接分析結果與古典冷軋模式非常相似,所以我們得到了更真實的冷軋摩擦 模式.因此觸面積比情形下,本模式結合了潤滑劑在表面粗度干涉下之液 動行為及因鈑材塑性變形而影響表面峰變形之分析。其數值分析結果與古 典的冷軋摩擦模式非常相似,所以我們得到了更真實的冷軋摩擦模式。因 此我們進一步探討了不同的加工條件下,對於使用乳液潤滑之冷軋製程的 摩擦影響。

An analytical model for strip rolling operating with the lubricants of the oil-in-water emulsions in the mixed regime is developed. The model of lubricant film formation in strip rolling with oil-in-water emulsions utilizes the dynamic concentration theory of Schmid . Under the condition of large fractional contact area ,the model combines an alternative average Reynolds equation for longitudinal surfaces with an analysis for the influence of bulk plastic flow onthe effective hardness of the strip asperite and an approach to allow for theinfluence of roughness on the lubricant flow in the mixed lubrication .The numerical results are very similar to the classic frictional models of the rolling processes, so we can get the more realistic frictional models for rolling operating with the oil-in-water emulsions. The implications of the numerical results with respect to the lubrication of the rolling processes will be discussedd.
