Abstract— Rolling aluminum and its alloys is one of the ... The aluminium cold rolling mill can process the Aluminium coil in thickness of 6-10mm from casters and hot rolling. The proceed materials can be offered to produce sheet, strip, can,
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.

Sep 11, 2014· Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes.
Oils, soap emulsions, fatty acids are used as lubricants during hot rolling non-ferrous metals. Mineral oils, paraffin, fatty acids are used for cold rolling. Normally, foe ferrous alloys no lubricant is used. 1.7 Rolling mill control: Production of continuous sheets and strips is one of the attractive features of modern rolling mills.

Rolling equipment is roughly divided into three kinds; namely, hot rolling mills, cold rolling mills, and foil mills. Usually, rolling is performed by applying a load to the materials by forcing them vertically through a pair of work rolls. The work rolls are deformed by the high load during the rolling process.

alloys since a process of homogenisation takes place which renders the material in the best condition for rolling and the achievement of subsequent properties. The strip from the hot rolling mill is coiled for transport to the cold mill which might be on the same site or elsewhere. Cold mills, in a wide range of types and sizes are available ...
We have a quality range of Aluminum Rolling Mill, which is used in forming immaculate aluminum strips through trimming and tearing while going through rolling mills in its re-crystallized form. They are formed through two methods which are hot rolling and cold rolling process.

rolling mills (8 stand roughing rolling mill, 4 stand intermediate rolling mill, and 4 stand finishing rolling mill) was built by Morgan-Sumitomo Heavy Machinery Co. Ltd.. In the 1980s, the aimed qual-ity of products was shifted toward high-value-added special steel quality, and, to achieve this, in 1986, a three-roll finishing rolling
There is almost no end to the uses of high-grade steel strip in today's world. They include everything from aircraft to beverage cans. That explains why we design our cold rolling mills to be just as versatile. What's important to you are not only high flexibility and product quality, but also sustained, cost-effective operation of your plants.
The use of aluminum has increased in many applications over time. Aluminum alloys offer adaptable tensile strength levels between 60 and 530 MPa, good castability and formability, good chemical resistance, versatile possibilities of surface treatments, and high electrical as well as thermal conductivity.

Flatness control in rolling processes is widely used for steel and nonferrous metals, such as aluminum and copper. We developed a shape roll by applying the principle of pneumatic bearing and supplied the first flatness control system (hereinafter called IHI Sheetflat) to an aluminum cold rolling mill in 1985.(1)
