Abstract: The heat transfer process in the laminar cooling system of hot-rolled strips is analyzed to develop the air/water-cooling mathematical models so as to control cooling process. As linear regression models, they are different from the theoretical expressions in term of exponential temperature drop of which the regressive data can be collected in situ. So, they are more practical and in simpler from with higher accuracy. The setting values, including presettings and that for modification, in calculation of laminar cooling and how to realize them in programming are described in detail. High cooling capacity, wide range of cooling rate, favourable running and satisfactory control effect feature the cooling system. It will meat the requirements for smoothening rolling process and developing new products.
