1、防锈合金铝卷的出产加工方法归于轧制加工,又称为"压延"加工。一般选用两种方法:热轧和铸轧。
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热轧法的特色:在大塑性变形过程中,内部安排经历了多次回复、再结晶,将铸造状况的粗大晶粒破碎,显微裂缝合拢,使坯料在内部安排的均匀化、晶粒的尺度与形状、点瑕疵与线瑕疵浓度改变等铸造瑕疵方面,均取得显着改进。
(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使铸态安排转变为变形安排,大大提高了金属的加工工艺性能。特别是在深冲性能方面,热轧料有着铸轧料不行比较的优势。
(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铸轧法的特色:铸轧板的内部安排归于半铸态结构,晶体的方向性较强。与热轧相比,具有投资少、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、冷轧铝卷和热轧铝卷用处不同,冷轧铝卷多用于模具类,热轧铝卷合适冲压拉伸方面,相同的材质由于制作工艺不同,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、防锈合金铝卷能够分为冷轧和热轧,首要区别是以阳极氧化为区别,热轧铝卷能够做阳极氧化。
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、铝加工又被称为塑性成形,按铝材在变形过程中的受力与变形方法(应力-应变状况)分为:铸造、锻造、揉捏、旋压、拉拔、轧制、成形加工(冷压、深冲)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.
