Achieve Planning Accuracy & Production Efficiency for Hot & Cold Mill Scheduling

Blog: Apriso Blog

From controlling operating costs to maximizing profits, steel manufacturers must juggle a number of conflicting priorities. On top of this, optimal performance must be maintained, and this extends to the scheduling of hot and cold steel rolling.

However, it is often challenging to strike the right balance for performance and drive efficiency when considering the various complex rules and constraints around hot and cold mill scheduling. This entails both the process as well as the use of resources—in this case, getting the most value and use out of typically costly equipment like steel mills. In addition, steel mills are capital intensive and result in a bottleneck process, and in each process, there are different exceptions and disruptions. So, it is usually insufficient to create a single schedule and instead, frequent rescheduling is required depending on the situation.

Hot and Cold Steel Mill Scheduling

Hot and cold mill scheduling is all about being able to precisely determine:

Accurately planning steel hot/cold mill schedule slots based on available resources and pending orders is a tough task, even for the most experienced planner. Each schedule must take into consideration which slabs can be slotted in to extend the schedule and minimize the waiting time between casting and hot/cold rolling. Should a disruption occur—for example, when the temperature of steel fails to reach its target composition and needs to be recast—processes have to be rapidly rescheduled to ensure that orders are not delayed.

Key Improvement Opportunities

This process requires detailed scheduling days or even mere hours ahead, for which real-time material and scheduling visibility is needed. Having a solution that provides these key capabilities can unlock your organization’s potential to make these improvements:
