Abstract

The basic theory of cooling after rolling was introduced firstly. The cooling process of strip steel was summarized as three typical cases. On the basis of Time-Velocity-Distance (TVD) curve, the cooling time model in each case was calculated. By means of the measured finishing delivery temperature, coiling temperature and the Stefan-Boltzmann law, the temperature drop was calculated. Combining the cooling time with the temperature drop, the calculating model for cooling rate along the strip length direction was developed in hot strip mill. The achievement was applied to a hot strip plant successfully. With the help of the results of cooling rate, process parameters were set up and controlled accurately and conveniently.
