Resumo
Temperature control of cold rolled sheet annealing plays an important role in the product characteristics. Usually, there are two kinds of temperature control model used in the heating furnace , furnace temperature control and strip temperature control. As the control object of the later is strip temperature, the accuracy rate is better . In this article, dynamic speed model and preheating track control based on strip temperature control model are explained, which are applied in the strip temperature control of Baosteel NO.4 continuous annealing line. The result of different strip temperature control models is compared. It is concluded that new strip temperature control model can not only improve the response of temperature magnificently, but also decrease strip temperature fluctuation, it is suitable for cold rolled automobile sheet production.
