CUTTING-EDGE TECHNOLOGIES FOR ALUMINUM ROLLING MILLS
Unisons International is a single source supplier of process technology, mechanical engineering, automation and electrical engineering – offering a customized solution that fits your needs.
Driven by global demand, the market for aluminum strip and foil continues to grow. China’s demand exceeds that of all other countries and will continue to do so in the coming years. Steady growth in demand for automotive and packaging outside China means plants must continually optimize aluminum rolling processes to stay competitive. Increased rolling speeds and increased plant productivity are key factors for securing your position in the market. Although being able to increase quantity is important, the key factor is quality enhancement. The ability to provide aluminum strip and foil in customized qualities is increasingly crucial. Your customers in aerospace, automotive, commercial transportation and packaging as well as construction require even tighter tolerances. To meet these demands, Primetals Technologies offers a flexible, easily adaptable rolling setup. As your customers’ market needs change, your plant must be capable of adapting. Short delivery times and fast production changeover are key criteria when your customers decide where to place orders. The ability to deal with product changes is therefore a vital factor in the economics of aluminum rolling. Logistic design has to be part of the plant solution, too. In recent years, the price of aluminum has dropped to a relatively unsustainable level resulting in the idling of primary plant. Warehouse stock levels have subsequently dropped from the pre-downturn levels due to sustained demand. Warehouse premiums will start to increase based on the dwindling stocks and low primary production. This means reduction of waste is an important target to maintain a competitive edge. Plant operations need to be optimized to increase capacity and improve quality, whilst decreasing operating costs. Easy maintenance is also important for improving plant availability and strengthening long-term performance.
ALUMINUM COLD ROLLING MILL - A SINGLE HIGH-PRECISION MILL FOR BOTH BREAKDOWN AND FINISHING
Unison's aluminum cold rolling mills offer a blend of innovative design and proven technology for both new and revamp projects. This enables strip to be produced at very tight tolerances and productivity levels resulting in maximum yield.
Markets served by customers include transport, construction and packaging. An accurate mill setup is crucial for meeting quality requirements. For this reason, Primetals Technologies cold rolling mills use physical on-line process models. Our solutions also feature fully integrated process control, automation and drive systems using industry-standard platforms to allow for optimum rolling results at any time.
ALUMINUM FOIL MILL - EFFICIENT PRODUCTION OF HIGH-QUALITY, LOW-COST FOIL
Unisons designs the most advanced foil rolling mills in the world, combining the latest developments in automated foil feed, measurement and control to enable producers to achieve the best quality foil at the lowest cost.
As the demands on the quantity and quality of aluminum foil have increased, so have the demands on the equipment to produce the foil. At present, rolling mills are expected to roll foil to less than six microns thick in widths of up to two meters and be capable of speeds in excess of 2,000 meters/minute. To meet these expectations, Unisons include state-of-the-art features for high-speed operation while process support ensures record start-up time and the ability to achieve that the very first coil rolled following a changed mill set-up be saleable. Industry standards for key metrics are exceeded.
ALUMINUM HOT ROLLING MILL - HIGH-QUALITY PRODUCTION, MAXIMUM MATERIAL YIELD, AND SUPERIOR FLEXIBILITY
Unisons provides a full range of aluminum hot rolling mills for both new and revamp projects. With our flexible mill configuration, high-quality strip can be rolled in capacities between 100,000 to 800,000 tonnes per annum.
As demand for quality and quantity of rolled aluminum increases; so do the demands on production equipment. Unison's solution provides a synthesis of mechanical actuators, electrical and automation control systems and applied process know-how to deliver gauge, profile/flatness, temperature, and surface quality with the highest level of consistency.
COPPER COLD AND FOIL ROLLING MILL
UCM-Mill and X-Mill Technology for thin gauge rolling.
The X-Mill with intelligent shape control using Sheetflat is designed for ultra-thin strip/foil rolling. The rolls are arranged in an X configuration in which a pair of parallel back-up rolls support the small diameter work roll to prevent horizontal deflection. This enables stable and reliable thin-gauge rolling to be performed.
