制作鋁板的步驟有哪些你知道嗎?

鋁和鋁合金板帶材以熱軋狀況、退火狀況、各種級別的軟態和各種熱處理狀況供給鋁板。
Aluminum and aluminium alloy sheets and strips are supplied by hot rolling, annealing, various grades of soft and various heat treatment conditions.
熱軋前準備 首要包含鑄錠質量檢查、均熱、鋸切、銑面、包鋁和加熱等。
The preparation before hot rolling mainly includes quality inspection of ingot, soaking, sawing, milling, aluminium cladding and heating, etc.
半連續鑄造時冷卻速度很高,固相中的分散進程困難,鑄錠內部易構成化學成分和組織不均,如晶內偏析等,使塑性降低。
In semi-continuous casting, the cooling rate is very high, the dispersion process in solid phase is difficult, and the chemical composition and structure of ingot are uneven, such as intragranular segregation, which reduces the plasticity.


鑄錠表面有偏析浮出物、夾渣、結疤和裂紋等缺陷時,應進行銑面(見有色金屬合金錠坯銑面),這是保證制品良好表面質量的一個重要因素
When there are defects such as segregation float, slag inclusion, scarring and crack on the surface of ingot, milling surface (see milling surface of non-ferrous metal alloy ingot) should be carried out, which is an important factor to ensure good surface quality of products.
熱軋:鋁合金鑄錠的熱軋是為冷軋供給坯料,或直接生產熱軋狀況的厚板。
Hot rolling: Hot rolling of aluminium alloy ingot is to supply billet for cold rolling or directly produce thick plate in hot rolling condition.
熱軋工藝制度包含道次壓下率、軋制溫度、軋制速度以及潤滑冷卻等
Hot rolling process includes pass reduction rate, rolling temperature, rolling speed, lubrication and cooling, etc.
