| Abstract: | Cooling mathematical model of accelerating cooling control was designed for the use in some medium heavy plate plants, including the heat transfer coefficients of the air cooling and water cooling to the steels. Temperature distribution was calculated by applying finite difference method along with the direction of the thickness of the plate. The online applying of the cooling mathematical model showed more accuracy in prediction. Both the shape and the mechanical property of the cooled plate reached the design specification and satisfied the field production requirement. |
