摘　　要：正火后采取控制冷却是提高正火钢板力学性能的重要手段。从中厚板正火后的控制冷却装置的设备构成和功能角度,详细说明了控制冷却系统在满足控制冷却的速度控制、板形控制上的设备设计特点。正火控制冷却系统达到了6～80mm钢板的冷却速度范围在2～20℃/s,冷却后钢板板形平直,30mm以上厚度钢板的性能合格率达到98%以上。该生产设备运行经济、可靠。The controlled cooling system after normalizing is an important measure for improving the mechanical properties of steel plate. In this article, the structure and the function design characteristics for controlled cooling system after normalizing heat treatment is introduced in details for the demand of cooling ratio and cooling flatness control. For 6 ～ 80mm steel plate, the following targets are achieved by the controlled cooling system, such as cooling ratio 2 ～20℃/s,flat for a whole plate, above 98% mechanical properties qualified ratio for the thickness 30ram steel plate. The cooling system runs reliably and low costly in the practice.
