Seco Warwick, Meadville, Pa., announces that its updated aluminum processing technology enables operators to load multiple bases while the furnace processes the first load, then moves to the next. Then the cooler moves to the heated product, locks in place, and cools the logs on the same base. This system reduces cycle time by eliminating the need to transfer product to stationery coolers. The automated control system is fully automatic with PLC controls, variable frequency drives and operator interface to ensure optimum system efficiency and ease of control.
“We partnered with the Seco Warwick design team to create a unique solution for our facility combining state-of-the-art heat processing technology with safe, efficient production planning to automate and streamline our material handling operation,” stated Steven Richardson, president of Ohio Valley Aluminum Company (OVACO).
“Our goal is to design the most efficient systems for our customers not only in terms of heat transfer technology, but also operator friendly control systems and material handling designs to meet each location’s unique requirements,” added Jonathan Markley, Seco Warwick Managing Director.
The furnace utilizes Seco Warwick’s patented reversing airflow design with upstream/downstream temperature control using an axial flow fan wheel that reverses rotation on a timed basis, in turn reversing the direction of the horizontal airflow through the load. The air stream temperature is monitored and controlled on each side of the load. A thermal head is used during the early stages of the cycle for fast, efficient heating. This design increases both the heating rate and temperature uniformity of the load compared with one-way airflow, resulting in better efficiency, lower fuel cost, and improved metallurgical results.
