Laminar cooling is an important feature of computer process control for hot strip rolling, and the mathematical model is its core. For 1 700 mm hot strip mills production line in Ansteel Anling Iron & Steel Co.,Ltd.,in view of the different laminar cooling control mode and the model function, this paper discusses the realization methods of setting and dynamic control setting calculation and coiling temperature self-adaption by fine temperature adjustment coefficient and correction factor. A set of coiling temperature curves measured in field for different steel grades and specifications are giv-en. Application results show that the model has higher control precision.
