Manufacturing Process of Aluminium Slug for Tubes

Manufacturing process of aluminium slug for tubes consists of melting, hot&cold rolling, punching, annealing, surface treatment and packaging.
aluminium slug for tubes
At the beginning of melting, aluminum ingots are put into a melting pot which is heated to melt the ingots. Melted aluminum liquid is stirred continuously, and aluminum dross is removed from the liquid at the same time. When the liquid gets clean and even enough for rolling, it is discharged through outlet of the melting pot, the temperature of which must be just right for the liquid. The liquid has also to go through a filtration process before being poured into a casting machine which rotates at an even speed to make aluminum liquid form into strips of given thickness and width around the casting wheel. The aluminum strips are then treated immediately by a hot roller. After a short of cooling, the strips go through a cold rolling step, during which it’s pressed into coils of desired thickness. In the punching process aluminum coils are first flattened and then punched into aluminum slugs of set size. The slugs falls down on a conveyor, and aluminum wastes are cut into pieces and sent back to the melting pot. The purpose of annealing is to reduce strength and improve ductility of aluminium slug for tubes. The whole procedure lasts about 12 hours. Surface treatment helps to obtain aluminium slug for tubes with rough surface. The slugs are kept rolling and knocking with each other in a machine. Then finished slugs is packaged automatically. The packaging machine send slugs into each box until it comes to a set weight. Generally speaking, 40 boxes are placed together on a wood tray that is wrapped safely for long travels.

Slitting of 1mm 2mm 4mm aluminium strip

图片
What kind of machine is used to make aluminum sheets into 1mm 2mm 4mm aluminium strip belts? Many people might think about a shearing device, but they are actually dealt with by a continuous slitting unit of a similar working principle to that of a shearing device. The difference lies in the point that there is no pause of shearing with a continuous slitting unit. Generally, the mother roll, namely, an  aluminum coil  to be slit, is placed. During the slitting process, the coil roll is divided into several belts which are further rolled into narrow aluminium strip rolls. The slitting method of both  1mm 2mm 4mm aluminium strip  or other aluminum strips can be divided into two types: a straight pull type and a loose sleeve type. The straight pull type refers to the method that aluminum strip rolls are kept in tension from being fed into the unwinding sail to being coiled by the coiling machine, and this production method is suitable for trimming and intermediate ...

Diamond Embossed Aluminum Sheet Application

The  diamond embossed aluminum sheet  refers to aluminium sheets with diamond patterns on the surface. In addition to 1000 series, 5005 and 3003 are frequently applied alloys as well. 5005  diamond embossed aluminum sheet s can be used for conductivity materials, cookware, instrument panels, electronic shells and building ornaments. Their anodized film proves to be brighter than that of 3003, and the color matches perfectly with that of 6063 aluminum alloy products. Generally speaking,  diamond aluminum checker plate s are sold by the unit of pieces. In international business the unit of metric ton is frequently used as well. Their thickness ranges from 1.7mm to 8mm, but those between 2mm and 7.75mm prove to be the most popular. The width is from 1010 to 1500, among which 1250 and 1500 are most frequently adopted. Embossed aluminum sheet s with different patterns usually match varied application scope. Five-bar and one-bar sheets are mostly used for anti-skid pu...

Embossed Aluminium Coil Patterns And Applications

图片
If you have ever used an escalator you might have noticed that there are partition panels respectively at the bottom and top of the escalator. These partitions are usually paved with  embossed aluminium sheet  coil that have a good pressure bearing capacity and are made of composite metals. As a matter of fact, there are various patterns and applications of embossed aluminium coil, and here we will give a simple introduction. 　　Patterns 　　Aluminum sheets with patterns on the surface is called embossed aluminum sheets or  aluminium tread plate . Pattern shapes include lentils, diamonds, round beans, and oblate mixed shapes. The market is most common in lentils. 　　Application 　　The aluminium tread plate has beautiful appearance, excellent anti-slip property, enhanced performances, and material-saving advantage in production. It is widely used in transportation, construction, decoration, equipment, floor, machinery, shipbuilding and other fields. Generally speaking,...
