Conventional Rolling. Aluminium slabs are heated to a temperature of around 525°C and then passed repeatedly through a hot rolling mill until either the required plate thickness is obtained or until the metal is thin enough (generally about 3 mm thick), to be coiled ready for cold rolling – the last 3 or 4 hot rolling passes are usually ...
At the reversing mill, rolling speed, roll bite, and coolant flow may be optimized only with a precise real-time knowledge of metal temperature. The low and highly variable non-greybody emissivity character associated with this complex aluminum process dictates the use of the most sophisticated multi-wavelength infrared pyrometers as the ...
The pusher furnace heats, softens, and conditions the scalped ingots for the hot rolling process. Hot Mill - Reversing Mill ... Finishing Mill. The finishing mill rolls the 1 inch slab from the reversing mill into a coil of aluminum sheet that is about one-tenth of an inch thick. The resulting "hot band" coil is then moved to a cooling area ...
Aluminium is reduced to the required uniform thickness at the rolling mill, and any necessary surface finish is applied before coiling. Temperature monitoring is essential to optimise the process, and detect potential mill breakdown problems.

Aluminium rolling lubrication strongly influences both mill productivity and metal quality. The various rolling processes and lubricants are discussed here.
Rolling. Plate materials are manufactured by rolling. Rolling is one of the processing methods, in which a pair of rolls installed in parallel is rotated to roll out an aluminum ingot called a slab into a thinner product. Aluminum rolled products are indispensable for daily life. They are used in a broad range of applications including packages ...
Hot Rolling Mill. Unsurpassed Control to Optimize Your Process. As an aluminum manufacturer, you're well aware of the complexities of rolling hot flat products to achieve minimum thickness tolerances and ensure the finished material meets precise specifications and the highest final quality. And, this challenge is compounded by trying to ...

We use the AA (Aluminium Association) standard as our reference but generally control our product to tighter internal standards. Both of our rolling mills are ISO9001 certified. With the help of the ISO Quality Management System, we continually improve our company's performance and have established a highly reliable and stable process.
It's a steel fabrication process involving passing the metal through a pair of rollers. There are two main types of rolling process: Flat rolling – the finished product is a sheet. Profile rolling – the finished product is a bar or rod. The process always starts with hot rolling. Hot rolling refers to the process of rolling steel at a ...
ping a new cold rolling mill for aluminum, thus ideally covering and aligning the enti-re process chain for the production of flat aluminum products. A cold rolling mill in a 4-high or 6-high design, with perfectly ali-gned equipment interacting with the me-chanical equipment, the technological con - trols, and the drive system.
Aluminium sheet fabrication and processing. J. Hirsch, in Fundamentals of Aluminium Metallurgy, 2011 23.3.5 Cold rolling. The same design principles described above for hot rolling are also valid for cold rolling and the related mill configurations. The cold rolling process runs at room temperature and usually under oil lubrication.
Flexibility and productivity in cold rolling of aluminum. SMS group offers single-stand cold rolling mills for a broad spectrum of aluminum alloys and thin strip and multi-stand tandem cold mills as the solution for a large production capacity. We completed our portfolio of cold rolling mills by the EDT rolling mill, especially designed for ...
The subsequent rolling operation in the high-speed tandem mill diminishes the interpass RX process while self-annealing might occur during the cooling of coiled hot rolled strip (35,36). The effect of strain mode and hot rolling parameters on the microstructure and texture evolution is summarized in Figure 4 .
