Rolling is called the process of plastic deformation of the initial blanks (ingots, castings), when the parent metal passes through a pair of rotating rolls, performing its reduction in the vertical direction. Hot rolling has two varieties — flat and volumetric.
Flat and profile deformation
In flat rolling, the final product is a roll, and for profile (bulk) rolling, wire, rod, or workpiece with a more complex cross-section. Since the temperature of recrystallization of metals is different, the rolling temperature can not be considered a determining factor: for example, lead rolling at room temperature should be considered hot (recrystallization and grain size changes in the metal occur), and rolling tungsten below 1800 ° C should be considered cold (recrystallization and dimensional change grains in metal do not occur).
When hot rolling, the yield point and the hardness of the metal do not practically increase, and the ductility of the heated metal increases. This makes hot rolling a less time-consuming and expensive process than cold rolling. Company Avek Global offers to buy rolled metal at an affordable price from the manufacturer in a wide range. The supplier provides delivery anywhere in the continent. The price is optimal.
Urgency of application
Hot rolling is used to produce hot rolled steel, which is used in the production of special equipment (for example, rails), in road construction and mining machinery.
Rolling mills are divided into longitudinal and transverse rolling mills, into sheet and profile mills. Classification and operational differences between the sizes of rolling mills usually produce by the following factors:
- On the limiting sizes of a cross-section of a rolled workpiece;
- On the width of the rolled material;
- By the number of stages (passes) of rolling, which, depending on the ductility of the metal and the temperature of its heating, can reach 3… 4;
- By drive power;
- On the degree of automation control rolling mill.
Advantages and limitations
The technology provides:
- Significant reduction in effort during metal processing;
- Increased productivity due to reduced number of passes;
- Reducing the energy intensity of equipment.
However, the technology does not give a sufficiently high accuracy of the final profile, in addition, it is necessary to clean the surface of scale.
