Efficient secondary cooling water control level slab continuous casting process and quality are closely related. Casting solidification heat transfer model is the basis of process control and optimization, heat transfer model based on determining the secondary cooling system is the most widely used method for casting production process can be simulated. However, when considering the many factors affecting the production and input conditions change significantly, real-time and strain of this method is not guaranteed. Therefore, the artificial intelligence optimization algorithms such as genetic algorithms, neural networks, fuzzy controllers, introducing continuous casting secondary cooling water distribution and dynamics of optimal control methods, the rational allocation of caster secondary cooling water and dynamic control is important.

In order to more accurate simulation the solidification of billet continuous casting. The measured shell thickness and surface temperature have been used to revise the heat transfer model. The calculated results of the model are in excellent agreement with the experimental ones based on an actual casting machine. The revised model can excellent to simulate the billet solidification process. So it provides the possibility for better simulation the dynamic solidification process and optimizing of the secondary cooling water.

A mathematical heat transfer model was built to simulate temperature, shell growth and phase transformations in continuous casting based on the technical conditions of the bloom caster of some steelmaking plant. The simulation result is coincided with the measurement. The effects of the operation parameters including casting speed, bloom size and steel melt superheat on the solidification process were discussed and the means of enhancing the bloom temperature was brought forward. The research results have been applied in the practical manufacture process to compute the best casting speed, to control the flow rate of secondary cooling water and to optimize the spray pattern of secondary cooling zone. The bloom quality and productivity could be improved.
