To improve billet quality and the trackability and stability of secondary cooling water during continuous casting, the tundish temperature is introduced into the water distribution for secondary cooling to design the relevant control system, based on the water distribution model, tundish temperature, surface temperature and fuzzy self-adaptive PID. A spray cooling system is thus set up for simulation in laboratory to test the step signal from the conventional, integral separated and fuzzy self-adaptive PID controllers and the simulated casting. The simulation test results show that the fuzzy self-adaptive PID controller´s performance is better than the other two controllers, which provides a foundation for further study and application.
