Heat transfer analysis of hot-rolled coils in multi-stack storing

Steel strip coil is the final product of the hot-rolling process. A model for cooling in hot-rolled coils is presented. Several important factors such as coiling temperature, oxidized layer thickness, pressure between different layers of a coil and varying ambient temperature are considered in the model. A computer code based on the model is developed. Satisfactory agreement between experimental and computational results confirms the accuracy of the model. Effects of some factors such as coiling temperature and ambient temperature on required cooling time of both single and multi-stack storing of coils are presented.
