ALUMINIUM CIRCLE

Chongqing Lanren aluminium Co.,Ltd was established in 2008.We are cookware manufacturer in China.And aluminium circle is our strong product.Aluminium circle also called aluminium disk/discos.

We introduce advanced aluminium circle production equipment, effectively improve production efficiency and material utilization, shorten the delivery cycle. Our company strengthened the control of the grain size and elongation of the coil, Respectively cold rolled and hot rolled aluminium circle sheet was launched,and cover 1, 3, 5, 8 series alloys. Complete product range, thickness 0.4-10.0 mm, diameter 60 -1200 mm, tolerance and composition in line with national standard requirements.  

Two state-of-the-art disc blanking presses combined with open shear processing enable our facilities to supply a diverse range of markets. aluminium circles are specialized products that are mostly used in the production of cookware, traffic signals,lighting lampshade, gas containers, automobile brakes and spinning. Our metallurgical processes ensure availability of deep drawing quality specifications that match these demanding applications.

We have CC and DC materials,this is the difference between DC and CC material,

1. Hot rolling process( Direct Cast rolling-DC): melting casting → slag removal → milling surface → heating → hot rolling → cold rolling → finishing rolling 

After the process of melting and casting into an alloy liquid, the process is to remove slag, about 1% -5% of the total amount, and then form an ingot,

Due to the high temperature in the casting process, impurities are attached to the surface of the alloy, and the impurities cannot be completely removed by the slag removal process.

Therefore, after forming the ingot, it is necessary to mill the face and mill the thickness of the ingot surface to about 20mm to reduce the impurities of the alloy.

The ingot is heated at a high temperature to maintain a certain temperature to recrystallize its internal structure. After a long period of high constant temperature, the crystallization will be more uniform and the grains will be more delicate, and then rolled under high temperature to form a hot rolled billet ,

Finally, cold rolling and finishing rolling.

2. the casting and rolling process(Countious Casting Rolling-CC): melting casting → crystal cooling forming → cold rolling → finishing rolling     

First, the aluminum ingot and the required alloy are directly cast to form an aluminum alloy liquid. It is then cooled by a crystallizer to form a cast-rolled billet of the desired width. Cold rolling and finishing rolling are actually completed in one process. The casting and rolling billet is cooled to below a certain temperature with lubricant for rolling, and finally the aluminum material is formed.

Compared with the cast and rolled billet, the hot rolled material has less impurities, so the corrosion resistance is much stronger, especially against seawater.

At the same time, due to the recrystallization process, its internal structure is more stable and uniform, the performance of the formed aluminum material is better, and the ductility is better than that of the cast and rolled material. The surface is brighter. Compared with the hot rolling process, casting and rolling does not need to go through the slag, milling, heating, hot rolling and other processing processes, so casting and rolling is also commonly known as cold rolling.

Different circle for different usages could help you save a lot !!!
