The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

The first commercial aluminum-magnesium-silicon alloy (51S) was developed and brought to market by 1921. 18 The introduction of alloy 61S (6061) in 1935 filled the need for medium-strength, heat-treatable products with good corrosion resistance that could be welded or anodized. Alloy (62S) 6062, a low-chromium version of similar magnesium and silicon, was introduced in 1947 to provide finer ...

Rolling process breaks and offsets the lattice planes of the material and increases the dislocation number, which results in material to resist the deformation and making it harder and stronger. Rolled material shows an elongated grain structure (Figure 1). 2. Types of Cold Rolling Mill Strip rolling can be done with different type of mills

Genetic algorithm based multivariate calibration models were generated for infrared spectroscopic determination of aluminum rolling oil additives and contaminants such as gear and hydraulic oils. Two different additives and six different suspected

the rolling process, especially in a cold strip mill. If the thickness variation of the hot-rolled aluminum strip can be reduced, it will be possible to increase the production speed of the cold strip mill. These claims set new demands on the acceptable rolling forces and torques which, together with the roll pass design, have a significant ...

A 300-mm-wide strip 25-mm thick is fed through a rolling mill with two powered rolls each of radius = 250 mm. The work thickness is to be reduced to 22 mm in one pass at a roll speed of 50 rev/min. The work material has a flow curve defined by K = 275 MPa and n …

aluminium rolling mills up to speed. This includes the most powerful roll drives for higher throughput. State-of-the-art mechanical and hydraulic solutions optimize performance and operational efficiency. Online process models and neural networks will enable you to produce more

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, PS sheet, foil and precision raw material for further processing. According to the gauge of the coils, it can be

Aluminium foil is produced by rolling sheet ingots cast from molten billet aluminium, then re-rolling on sheet and foil rolling mills to the desired thickness, or by continuously casting and cold rolling.To maintain a constant thickness in aluminium foil production, beta radiation is passed through the foil to a sensor on the other side. If the intensity becomes too high, then the rollers ...

Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll -

process for thin aluminum strip and sheet. Effective quality control at this stage, by monitoring dents, scratches and other surface defects, can protect from claims and reduce costs throughout the production process. The speed of the cold rolling mill and the hot, wet environment (which leads to …
