Technical Characteristics

Rolling is a process of plastic deformation of initial billets (ingots, castings), when the feed metal passes through a pair of rotating rolls, which carry out its compression in the vertical direction. Hot rolling has two varieties - flat and volumetric.

Plane and section rolling

Rolling a flat material as a coil, and rolling a section (volume) material as a wire, rod or billet with a more complex cross-section. Since the temperature of recrystallization of metals varies, the temperature of rolling cannot be considered a determining factor: for example, the rolling of lead at room temperature should be considered hot (recrystallization and change of grain size in the metal occurs), and the rolling of tungsten below 1800 °C should be considered cold (recrystallization and change of grain size in the metal does not occur).

Hot rolling

During hot rolling, the yield strength and hardness of the metal practically does not increase, but the plasticity of heated metal increases. This makes hot rolling a less time consuming and expensive process than cold rolling. Avec Global offers to buy a wide range of rolled steel at an affordable price from the manufacturer. The supplier provides delivery anywhere in the continent. The price is optimal.

Relevance of application.

Hot rolling is used to obtain thick plates, which are used in the production of special equipment (such as rails), in road construction and mining engineering.

Equipment

Rolling mills are subdivided into longitudinal and cross mills, plate mills and section mills. The classification and operational differences between the sizes of rolling mills are usually made according to the following factors:

1. By the limiting dimensions of the cross-section of the rolled billet;
2. By the width of the rolled material;
3. By the number of stages (passes) of rolling, which, depending on the plasticity of the metal and its heating temperature, can reach 3 ... 4;
4. By the power of the drive;
5. The degree of automation of rolling mill control.

Advantages and limitations

The technology provides:

1. Significant reduction of forces during metal processing;
2. Increased productivity due to a reduction in the number of passes;
3. The reduction of energy consumption of the equipment.

However, the technology does not give a sufficiently high accuracy of the final profile, in addition, it is necessary to clean the surface from scale.
