Abstract：The new improved technique of steelmaking-continuous casting brought about the changes from fixed furnace counts to a fixed time for evaluation mode of tundish lifetime and a corresponding optimization model for tundish plan was constructed. The effects of steel grade, casting width and draw-speed to casting time were taken into account in the model. And then, an optimization method combining heuristic algorithm and DNA evolutionary algorithm was proposed to solve the model. Three heuristic algorithms were designed and detailed steps of DNA evolution process were given based on heuristic algorithm. By simulating on the real production data, the result shows that the proposed optimization method may improve the utilization rate of tundish and is effective.
