Rolling is one of the most critical stages in the production of aluminum sheets and discs. During this mechanical process, the thickness of the aluminum is reduced while the material is shaped to the required dimensions. The slabs are passed through two or more rollers until the desired thickness and form are achieved. In addition to modifying the shape and thickness of the aluminum, the rolling process also helps improve its physical properties.

Rolling is carried out using two main methods: hot rolling and cold rolling. In hot rolling, the aluminum is processed at a temperature above its recrystallization temperature. This elevated temperature increases the material’s formability and flexibility while helping prevent cracking. Hot rolling also enables the production of aluminum sheets with reduced thickness.

In cold rolling, the process is typically carried out at room temperature and below the recrystallization temperature of aluminum. This stage generally follows hot rolling and is used to achieve thinner gauges and greater dimensional accuracy. Cold rolling plays an important role in maintaining uniform sheet thickness and precise dimensional control, while also improving the material’s properties by increasing the strength and hardness of the aluminum.

Modern and advanced equipment is used in the rolling of aluminum slabs, enabling the production of high-quality aluminum sheets in a wide range of dimensions and thicknesses. This versatility makes aluminum sheets suitable for applications across various industries. With nine modern cold rolling machines, Tolou Navard Pars has the capacity to manufacture a wide range of aluminum sheets and discs in high production volumes.
