Seco/Warwick Supplies Annealing Furnace in Jalisco, Mexico
Seco/Warwick Corp. (Meadville, Pa.; http://www.secowarwick.com) sold an annealing furnace system to process transformer cores at a rate of 1,715 pounds per hour to Cooper Power Systems, a division of Cooper Industries Inc., for its Jalisco, Mexico facility. The furnace line has a versatile drive system with PC/PLC controls, allowing a wide range of soak times to accommodate different size transformer cores. The automated line can use both nitrogen and nitrogen/hydrogen atmospheres with auto flow control based on process oxygen set points. Flow and mixture are automatically adjusted and maintained. In the cycle, the workload passes through a preheat/burnoff chamber, a heat and hold chamber, a controlled cooling chamber, a water-jacketed fast cool chamber and an exit purge chamber. After the exit purge, the transformer cores are transferred to an air blast cooler for final cool down. A complete closed loop self-contained water treatment/cooling system is provided to minimize utility requirements (water use) and to maintain optimum water conditions.
