Embodiment Construction

[0060] The present invention will be described in detail below in conjunction with the accompanying drawings. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0061] After receiving a batch of orders, the factory must first go through quality and production design to turn the order into a producible contract, and then close the contract through the contract, that is, select the meeting date from the given production contract according to the priority of the delivery date The contract slab of production capacity is imported into the local database;

[0062] Hundreds of thousands of slabs obtained through material design, the steps for slab group furnace are:

[0063] Firstly, the furnace slab to be assembled must be selected from the pool, and the furnace planning model should be established. The furnace plannin...

Abstract

The invention discloses a method for arranging heat in a steel making continuous casting production process, and the method comprises the following steps sequentially: establishing a local database and selecting plate blanks from a pool according to the contract; selecting a furnace plate blank to be arranged from the pool and establishing a heat planning model; converting the heat planning model into a prospective traveling salesman problem; solving a heat planning prospective travel business problem model based on an intelligent optimization algorithm and finding an optimal heat plan; and arranging the plate blanks into the furnace as a main character according to the determined optimal heat plan. By using the method for arranging heat, the heat arranging plan is arranged without pre-determining the time of heat to be arranged. By using the invention, one plan is arranged in several seconds, the time can be precise to second, the utilization rate of the equipment is greatly improved and the steel making continuous casting yield is remarkably improved.

Description

technical field [0001] The invention relates to the field of metallurgical automatic production, and relates to a method for grouping furnaces in a steelmaking and continuous casting production process based on a sequence inversion improved discrete particle swarm algorithm and a quasi-traveling salesman problem model. Background technique [0002] The iron and steel industry is an important basic industry of the national economy, and our country is the largest steel production country in the world. However, since the iron and steel industry is a high-energy industry, energy prices have skyrocketed in recent years, and how to save energy has attracted more and more attention from the iron and steel industry. In order to reduce the increase of fuel cost caused by the increase of fuel price, iron and steel enterprises all over the world have carried out the transformation of production equipment and the innovation of production technology. [0003] After my country's accessio...
