| Abstract: | According to the theory of heat transfer and solidification, a mathematical model used for secondary cooling zone of slab caster was established. The influence of space and time pacing on the result of numerical calculation was studied. A dynamic tracing program and a new control model using the virtual casting speed as control parameter was developed. The dynamic tracking program of secondary cooling was used to simulate the casting with varied speed. The results show that the virtual casting speed control model is superior to the actual casting speed control model. |
