Turnaround time: 18 hours; operation time per furnace: 9 minutes; three-stage maintenance; 5-2 sequencing; 100-hole carburizing chamber – how to plan coke pushing operations.
How should the three maintenance periods be arranged appropriately?
There used to be an Excel file on this topic in the forum
100 divided by 3 equals 33.333, which is either 33 or 34 (the number of batches must be an integer). If it is divided into three segments, the number of batches per segment will be 33, 33, and 34 respectively. The cycle time is 18 hours; therefore, the time for each segment is 18×60÷3 = 360 minutes. The time required to produce batches in each segment is (33–1)×9 = 288 minutes； 288min ； 297 min; the maintenance time for each segment is 360 – 288 = 72 min ； 72min ； 360-297=63min
