Key Laboratory of Process Industry Automation, Ministry of Education, Northeastern University, Shenyang Liaoning 110004, China; 2. Research Center of Automation, Northeastern University, Shenyang Liaoning 110004, China) Abstract: Being the last process in steelmaking, the continuous casting process is the connecting bridge between the iron production process and the rolling production process; its scheduling is crucial for ensuring the whole production process operating in a well-organized rhythm with low production cost. According to properties of casting process and casting machines, we develop a schedule for continuous casting process, and then, apply the in-depth priority search algorithm to minimize the makespan of the continuous casting process. This algorithm doesn’t use any traditional scheduling method. Field data in a domestic steel plant employing this approach for scheduling the continuous casting process shows smooth operations in production and reduced production cycles. This demonstrates that this easy-implemented algorithm efficiently assists plant workers in scheduling the continuous casting process to achieve high productivity.
