由于铝材需要量的迅速增加,导致了铝材轧制技术的诞生.这种情况正与钢材轧制技术产生的情况相似.厚度为200～600毫米的半连续铸锭(为得到优质表面将铸锭铣面)在可逆式轧机上热轧成18～25毫米厚的板料.这种板料或相同厚度的连铸连轧板在400～200℃下温轧成2～6毫米厚的板材,然后卷卷.热轧带卷以高达600米/分的速度在单机架轧机(也可是可逆式的)或二重到四重轧机的串联式轧制生产线上轧到较薄厚度.通常带卷的最薄厚度(罐毛料)为0.15～0.25毫米.更薄的箔材通常是将其毛料退火,然后在不
The rapid increase in the demand for aluminum has led to the birth of aluminum rolling technology, as is the case with the steel rolling technology. Semi-continuous ingots with a thickness of 200-600 mm Ingot milling plane) is hot-rolled in a reversing rolling mill to a sheet thickness of 18 to 25 mm, the sheet or the continuous casting and rolling plate having the same thickness is rolled to a thickness of 2 to 6 mm at 400 to 200 ° C The sheet is then wound up Hot rolled coil is rolled to a thinner thickness in tandem mill lines up to 600 m / min in a single-stand mill (also reversible) or a double-quadruple-mill The thinnest thickness of the coil (cans) is 0.15 to 0.25 mm. Thinner foils are usually annealed with their wool and then
