Research on Hot Rolling Seamless Steel Tube Production Scheduling

The current production scheduling in a hot rolling seamless steel tube enterprise is manually completed and is not timely and accurate. Although ERP can effectively improve the production performance of the enterprise, the standard production scheduling flow of ERP software introduced by the enterprise is not completely applicable to production scheduling and practice for the production of hot rolling seamless steel tube which covers three main characters: complicated production process, multi varieties and low volume. In this paper, the current manual production scheduling flow is analyzed, the production scheduling flow is redesigned, and the essentials of hot rolling seamless steel tube production scheduling are pointed out to be batching, dividing furnace number and identifying production date/shift of every furnace. Finally, the batching rules as well as the methods/formulas of dividing furnace number and identifying production date/shift of every furnace are presented.
