摘　　要：针对热轧带钢超快速冷却过程温度控制,通过建立带钢冷却过程中的空冷、水冷温降模型,采用前馈、反馈与自适应相结合的温度控制策略,提高带钢的中间温度和卷取温度的控制精度,并应用于热轧带钢生产线。应用效果表明,带钢轧后温度控制达到了较高的精度,并有效地提高了带钢的力学性能。Aimed at the temperature control of the ultra-fast cooling process in hot strip rolling and by developing the combined strategy of feed-forward,feed-back and self-adaption based on the establishment of the air cooling and water cooling temperature drop model,the precision of middle temperature and coil temperature control was improved.The cooling system had been applied in a hot strip production line.The results show that the precision of temperature control reaches a high level and the mechanical properties of the strip are improved effectively.
