Abstract
Maintaining the shell surface temperature profile under transient conditions by spray water cooling in continuous casting of steel is important to minimize surface cracks. For this purpose, a real-time spray-cooling control system is being implemented on a commercial caster that includes 1) a software sensor for accurate estimation/prediction of shell surface temperature, 2) control algorithm and data checking subroutines for robust temperature control, 3) TCP/IP Server and Client programs for communicating between these two software components and the caster, and 4) a real-time monitor to display the predicted shell surface temperature profiles, water flow rates, and other important operating data. Simulation results demonstrate that the new control system achieves better temperature control performance than conventional systems.
