Coiling Temperature Control

Run out table cooling equipment and coiling temperature control (CTC) system, especially mathematic models of a hot strip mill were introduced. Heat transfer models such as air convection model, heat radiation model and laminar cooling model, process control models such as segment tracking model, feedback control model, self-learning model and case-based reasoning model were detailed described. Since online application of the new CTC system, the laminar cooling control system has been running stably and reliably with a high precision of coiling temperature.

Hot Strip

During the strip laminar cooling process, the switching of cooling valves is decided by different operating modes, initial and rolling-terminating conditions. Aimed at shortening the development cycle and at the same time assuring the quality and regularity of the controlling program, this paper has designed a hot strip laminar cooling prediction software adopting the RTW code generating technique. First, the Simulink model of the cooling process is built. Second, the model is converted by RTW into C code which can launch without Matlab. Finally, the graphical user interface design is completed with the generated code incorporated in. Experiment shows that the software developed with this method can gain the same results as Simulink model. The work of manual coding is substantially reduced. The combination of convenient modeling of Simulink and flexible GUI designing of VC can provide better reliability and practicability than traditional software developing.
