鋁單板軋(ya)(ya)(ya)(ya)制(zhi)工藝中，溫(wen)(wen)(wen)度(du)的(de)掌(zhang)控是(shi)重中之重。鋁(lv)(lv)單(dan)(dan)板(ban)(ban)軋(ya)(ya)(ya)(ya)制(zhi)溫(wen)(wen)(wen)度(du)包括開軋(ya)(ya)(ya)(ya)溫(wen)(wen)(wen)度(du)、終(zhong)軋(ya)(ya)(ya)(ya)溫(wen)(wen)(wen)度(du)以(yi)及卷取溫(wen)(wen)(wen)度(du)。這些溫(wen)(wen)(wen)度(du)對于鋁(lv)(lv)材軋(ya)(ya)(ya)(ya)制(zhi)時的(de)變形抗力、軋(ya)(ya)(ya)(ya)制(zhi)力、成(cheng)(cheng)品的(de)組(zu)織(zhi)、晶粒度(du)、力學性能以(yi)及板(ban)(ban)帶材的(de)表(biao)面(mian)狀態等都有(you)著直接(jie)影(ying)響(xiang)。其他次(ci)要參數，有(you)些許誤(wu)差(cha)或許對鋁(lv)(lv)單(dan)(dan)板(ban)(ban)成(cheng)(cheng)品的(de)質量影(ying)響(xiang)不大，但如果(guo)溫(wen)(wen)(wen)度(du)把(ba)控不好，對鋁(lv)(lv)單(dan)(dan)板(ban)(ban)成(cheng)(cheng)品質量的(de)影(ying)響(xiang)是(shi)巨(ju)大的(de)。特別對于鋁(lv)(lv)單(dan)(dan)板(ban)(ban)熱軋(ya)(ya)(ya)(ya)，只要有(you)1%的(de)溫(wen)(wen)(wen)度(du)預測差(cha)異(yi)，可(ke)能導致2% ~ 5%的(de)軋(ya)(ya)(ya)(ya)制(zhi)力預報差(cha)異(yi)。可(ke)見，1%的(de)溫(wen)(wen)(wen)度(du)誤(wu)差(cha)對鋁(lv)(lv)單(dan)(dan)板(ban)(ban)質量影(ying)響(xiang)是(shi)倍數級的(de)。因此，在鋁(lv)(lv)單(dan)(dan)板(ban)(ban)軋(ya)(ya)(ya)(ya)制(zhi)過程(cheng)中必(bi)須嚴(yan)格(ge)控制(zhi)溫(wen)(wen)(wen)度(du)，來(lai)(lai)不得半點馬虎。然而，鋁(lv)(lv)單(dan)(dan)板(ban)(ban)軋(ya)(ya)(ya)(ya)制(zhi)過程(cheng)引(yin)起(qi)的(de)溫(wen)(wen)(wen)降的(de)原(yuan)(yuan)因哪些呢(ni)？我(wo)們一起(qi)來(lai)(lai)了解(jie)下鋁(lv)(lv)單(dan)(dan)板(ban)(ban)軋(ya)(ya)(ya)(ya)制(zhi)過程(cheng)中軋(ya)(ya)(ya)(ya)件的(de)熱量損失原(yuan)(yuan)因。

    1、輻射散熱損失引起溫度降低。

    2、對流傳熱的散熱損失引起溫度降低(di)。

    3、鋁單板軋(ya)(ya)制過(guo)程(cheng)中扎件和軋(ya)(ya)輥接觸時的熱傳導(dao)損失(shi)引起溫度降低。

    此外，鋁單(dan)板塑性變形(xing)時會引起溫度上升，需注意。
