The main function of the Continuous Casting and Rolling Plant (Mill) is to produce aluminum products such as ingots and continuous casting coils. The plant is located next to the smelter in order to avoid liquid aluminum temperature loss during transportation. Once delivered to the mill, liquid aluminum is moved to the gas fired melting furnace for metal flux mixing and different alloys are added depending on target specifications. During this process impurities are removed and chemical composition is equilibrated.
