1、防銹合金鋁卷的出產(chǎn)加工方法歸于軋制加工,又稱(chēng)為"壓延"加工。一般選用兩種方法:熱軋和鑄軋。
1. The production and processing method of anti-rust alloy aluminium coil is attributed to rolling processing, also known as "calendering" processing. Generally, two methods are used: hot rolling and casting rolling.
①熱軋法的特色:在大塑性變形過(guò)程中,內部安排經(jīng)歷了多次回復、再結晶,將鑄造狀況的粗大晶粒破碎,顯微裂縫合攏,使坯料在內部安排的均勻化、晶粒的尺度與形狀、點(diǎn)瑕疵與線(xiàn)瑕疵濃度改變等鑄造瑕疵方面,均取得顯著(zhù)改進(jìn)。
(1) The characteristics of hot rolling method: in the process of large plastic deformation, the internal arrangement undergoes repeated recovery and recrystallization, crushing the coarse grains in casting condition and closing the micro-cracks, which makes remarkable improvements in the internal arrangement of billets, the size and shape of grains, the change of defect concentration and other casting defects.
②使鑄態(tài)安排轉變?yōu)樽冃伟才?,大大提高了金屬的加工工藝性能。特別是在深沖性能方面,熱軋料有著(zhù)鑄軋料不行比較的優(yōu)勢。
(2) Transforming as-cast arrangement into deformation arrangement greatly improves the processing performance of metals. Especially in deep drawing property, hot rolled material has the advantage that Cast-rolled material can not be compared.
③鑄軋法的特色:鑄軋板的內部安排歸于半鑄態(tài)結構,晶體的方向性較強。與熱軋相比,具有投資少、成本低、效率高的特色。
(3) Characteristic of casting-rolling method: The internal arrangement of cast-rolling plate belongs to semi-cast structure, and the orientation of crystal is strong. Compared with hot rolling, it has the characteristics of less investment, low cost and high efficiency.
2、冷軋鋁卷和熱軋鋁卷用處不同,冷軋鋁卷多用于模具類(lèi),熱軋鋁卷合適沖壓拉伸方面,相同的材質(zhì)由于制作工藝不同,它的物理性能相差很大。
2. Cold rolled aluminium coil and hot rolled aluminium coil have different uses. Cold rolled aluminium coil is mostly used for dies. Hot rolled aluminium coil is suitable for stamping and drawing. The physical properties of the same material differ greatly due to different manufacturing processes.
3、防銹合金鋁卷能夠分為冷軋和熱軋,首要區別是以陽(yáng)極氧化為區別,熱軋鋁卷能夠做陽(yáng)極氧化。
3. Antirust alloy aluminium coil can be divided into cold rolling and hot rolling. The primary difference is the difference between anodic oxidation and hot rolling aluminium coil can be anodized.
4、鋁加工又被稱(chēng)為塑性成形,按鋁材在變形過(guò)程中的受力與變形方法(應力-應變狀況)分為:鑄造、鍛造、揉捏、旋壓、拉拔、軋制、成形加工(冷壓、深沖)等加工方法。
4. Aluminum processing is also known as plastic forming. According to the stress-strain state of aluminum during deformation, it can be divided into casting, forging, kneading, spinning, drawing, rolling, forming (cold pressing, deep drawing) and other processing methods.
