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 establish-ment 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 pro-duction line.The results show that the precision of temperature control reaches a high level and the mechanical properties of the strip are improved effectively.
