鋁卷的生產(chǎn)過(guò)程主要包括以下步驟:鋁材準(zhǔn)備:包括鋁錠的熔煉和鑄軋,以獲得一定形狀和尺寸的鋁材。熱熔鑄造:將鋁材加熱至熔融狀態(tài),通過(guò)鑄造工藝形成一定形狀和尺寸的錠。預(yù)軋連續(xù)鑄軋:通過(guò)預(yù)軋工藝對(duì)錠進(jìn)行初步軋制,使材料更加均勻。冷軋:對(duì)預(yù)軋后的鋁材進(jìn)行冷加工,通過(guò)多道次軋制,逐漸減小厚度并獲得所需形狀和尺寸的鋁卷。退熱退火:在軋制過(guò)程中,鋁卷會(huì)受到強(qiáng)烈的塑性變形,導(dǎo)致內(nèi)應(yīng)力增加。為了消除內(nèi)應(yīng)力,提高材料的機(jī)械性能,需要進(jìn)行退火處理。退火溫度一般低于再結(jié)晶溫度,以避免晶粒長(zhǎng)大。精軋:退火后的鋁卷再次進(jìn)行精軋,以獲得更精確的厚度和更光滑的表面。涂層:為了提高鋁卷的耐腐蝕性和美觀度,可以在表面涂覆一層保護(hù)膜。剪切:根據(jù)客戶需求,將鋁卷剪切成不同長(zhǎng)度和寬度。以上是鋁卷生產(chǎn)的主要步驟,通過(guò)這些步驟可以獲得高品質(zhì)的鋁卷。

  The production process of aluminum coils mainly includes the following steps: aluminum preparation: including melting and casting of aluminum ingots to obtain aluminum materials of a certain shape and size. Hot melt casting: Heating aluminum to a molten state and forming ingots of a certain shape and size through the casting process. Pre rolling continuous casting: preliminary rolling of ingots through pre rolling process to make the material more uniform. Cold rolling: Cold processing of pre rolled aluminum materials, gradually reducing the thickness and obtaining the desired shape and size of aluminum coils through multiple passes of rolling. Annealing: During the rolling process, aluminum coils undergo strong plastic deformation, leading to an increase in internal stress. In order to eliminate internal stress and improve the mechanical properties of the material, annealing treatment is required. The annealing temperature is generally lower than the recrystallization temperature to avoid grain growth. Precision rolling: After annealing, the aluminum coil is subjected to precision rolling again to obtain more accurate thickness and smoother surface. Coating: In order to improve the corrosion resistance and aesthetics of aluminum coils, a protective film can be applied on the surface. Cutting: Cut aluminum coils into different lengths and widths according to customer requirements. The above are the main steps in aluminum coil production, through which high-quality aluminum coils can be obtained.
