Definitions
- an expected temporal temperature curve of the rolling stock at the rolling stock point is determined via the rolling stock cross section.
- the object of the present invention is to provide a cooling method and the corresponding cooling path model, by means of which the temperature of the rolling stock to be cooled and also its phases and phase transitions are correctly described.
- the problem is solved for the cooling process in that a heat conduction equation of the shape is used to determine the temperature profile in the rolling stock in the cooling section model
- the advantage of this approach is the possibility of coupling to the Fourier heat conduction equation without giving up the possibility of using an initial value problem solver for the coupled calculation of the degree of phase conversion p and temperature T.
- Rolld material width b and in a thickness direction x a rolled material thickness d together result in the rolling stock cross section of the rolling stock 1.
