Abstract

An optimization method of a ladle scheduling problem comprises the steps of: a coding mode of a solution, generation of an initial solution, generation of an initial reference set; updating of the reference set; subset generation method; and combination of operators. The optimization method of the ladle scheduling problem is a method of making a ladle scheduling plan combining liquid steel processing time and having controllability, and is an automatic method for fine regulation of a steelmaking-continuous casting scheduling plan. The method properly regulate the process time of liquid steel in a steel-making operation to improve the ladle turnover rate and reduce the heat energy loss of a service process on the premise of ensuring the ladle service liquid steel satisfaction (liquid steelquality).

Description

Technical field:

[0001] The invention belongs to the field of production automation, and specifically relates to formulating an optimization algorithm for ladle scheduling on the premise that the steelmaking-continuous casting scheduling plan has been generated, providing a scheduling schedule for the ladle serving molten steel process, and making a steelmaking-continuous casting scheduling plan An automatic method for fine-tuning. Background technique:

[0002] In the production of steelmaking-continuous casting, the ladle is accompanied from the time when the molten steel is tapped in the converter or electric furnace until the end of the casting in the continuous casting stage. When the high-temperature molten steel is waiting for the ladle, the temperature drops and heat energy is lost; improving the turnover efficiency of the ladle and reducing the temperature drop time of the ladle can correspondingly reduce the baking preparation time of the ladle. Therefore, for a g...
