Wire rod is made by drawing hot metal through shafts. The shafts form and compress the metal from different sides, thus turning a piece of metal into a long, thin wire. At the end of the rolling mill, this wire is wound on a special winder, with the help of which the rod is rolled into skeins for further cooling.

In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its re-crystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature.

The Cold Drawing Process for Steel Bars and Wire. Raw Stock: Hot rolled steel bar or rod coils are used as raw material. Because the hot rolled products are produced at elevated temperatures (1700 - 2200 Deg. F. i.e. hot rolling), they generally have a rough and scaled surface and may also exhibit variations in section and size.

end of the process). First the slabs from the caster are reheated in the re-heat furnace. After this they are moved, one by one, on a conveyor to the hot rolling mill. Here the slabs are rolled as often as necessary to reach the desired measures. After rolling, the steel is normally pickled to remove oxides from the surface. At this point,

Hot rolling process involves rolling the steel at extremely high temperatures, typically above 926 degree celsius, which is higher than steel's recrystallization temperature. The cold rolling mill's name is a bit of a misnomer as even in this process the temperature of the metal sheets reaches 50 to 250 degrees.

Rolling can be done either by hot rolling or by cold rolling. Cold rolling usually follows the hot rolling. During hot rolling of steels, the cast grain structure of steel achieved during the steelmaking process (usually large grains grown in the direction of solidification) is converted into a wrought grain steel structure.

If the mill heats the aluminum, this process is called hot working. The specific temperature range for hot working varies by alloy. For example, 3003 aluminum is hot worked at between 260 to 510°C (500 to 950°F), according to AZoM. Hot rolling prevents most or all work hardening and allows the aluminum to remain ductile.
