Title:
製鋼工程における排滓ポットの交換タイミングの導出方法
Document Type and Number:
Japanese Patent JP6818979
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of surely deriving a replacement timing of a discharge pot in a steel making step that does not cause uninterrupted continuous casting piece.SOLUTION: A method of deriving a replacement timing of a discharge pot in a steel making process according to the present invention is, when a steel making step 1 having a converter 2, a secondary refining device, a transportation device for transporting a continuous casting machine 5 and a molten steel ladle Z, and a sludge discharging field 7 for discharging a slag in the molten steel ladle Z is operated, a method of deriving a replacement timing for calculating a timing where the discharge pot 8 can be replaced in the slag discharge field 7, in which a mold assembly that becomes a basis is prepared, a necessary time necessary for each process for every steel species is determined, based on the mold assembly and processing time, a gantt chart is prepared, in the prepared gantt chart, whether there is an interval during which a non-utilization time of the transportation device exceeds a predetermined time or not is determined, in the case where an interval during which the non-utilization time of the transportation device exceeds a predetermined time is present, this interval is set to a replacement timing of the discharge pot 8.SELECTED DRAWING: Figure 1
