Abstract

The invention discloses a transport equipment steel ladle path compilation method of considering production equipment scheduling plan constraints. According to the method, indexes that a steel ladle transport path is shortest, lifting and laying frequency is minimum, interval time between two successively adjacent steel ladles in the same path is longest, a steel ladle transport temperature drop is minimum, and transport time is minimum are taken as performance indexes, conditions that the loading weight of a crown block on the path is greater than the weight of the steel ladle laden with molten steel, transportable time of the crown block on the path is in a specified range of a furnace charge plan, a path length is in an available path length range determined by the maximum speed of the crown block and the furnace charge plan, and a temperature drop of the transported molten steel in the path does not exceed a specified temperature range of a furnace charge process are taken as constraint conditions, steel ladle transport paths are taken as a decision variable, and a mathematical model of the problem is constructed; the multi-priority-based heuristic compilation method of the steel ladle path is designed; and steel ladle path priority is determined and the available paths are sorted according to importance degrees of the performance indexes on the bases of the layout of a plant area and the furnace charge plan, and the steel ladle transport path is decided.

Description

technical field

[0001] The invention relates to the field of ladle route preparation, in particular to a method for preparing ladle route of transportation equipment considering the constraint of production equipment scheduling plan. Background technique

[0002] After the ladle receives molten steel in the converter, it goes through the slag removal station (some molten steel does not go to the slag removal station), and then goes to the refining equipment for refining treatment; Or the molding station is ready for casting; after casting, the ladle is dumped to the corresponding slag dumping station; after the slag dumping is completed, the empty ladle is transported to the tilting table for inspection and treatment of the Ar blowing hole, nozzle, slide plate, etc. of the ladle . Check that there are several destinations for the processed empty ladle, directly go to the converter to receive molten steel, or go to the fast drying station to wait for receiving molten steel, ...
