Embodiment 1

[0054] The optimal scheduling method of single-layer furnace distribution based on linear programming strategy and pallet pre-division, including S1: the number of historically fired workpieces in a certain period of time is classified by volume for quantitative statistics, and frequency partitions are divided. S2: Furnace matching based on linear programming strategy, and frequency space is allocated on the pallet. S3: Based on time greed, put the corresponding artifacts into the corresponding partitions for operation.

[0055] The working principle / working process of the present invention is as follows: this method can rationally arrange the workpieces to be fired during the furnace matching process of steel production, and obtain the best plan for firing a large number of workpieces on pallets of different scales, effectively saving the furnace matching space. The firing cost is reduced, and the method has industrialization potential. The frequency partition is to count an...

Embodiment 2

[0057] First, divide a batch of workpieces into three categories according to volume: large workpieces of type A, medium-sized workpieces of type B, and small workpieces of type C, and count the number of workpieces fired for a period of time according to volume classification, which is recorded as n A ,n B ,n C , and the total amount is recorded as N. Calculate the historical firing ratio for frequency partitioning, i.e. Take the simplest integer ratio as the partition ratio of A, B, and C workpieces to be processed. In addition to the physical properties of the workpiece, it is also necessary to count the firing processing time when making statistics, so as to facilitate subsequent scheduling work.

[0058] The purpose of this program is to solve a set of frequency partition ratio placement minimum area, so the objective function is to minimize the tray area as the objective function. long p i and width q i Add a gap constant t0 to the lower projection of the workpiec...

Abstract

The invention discloses a single-layer furnace distribution optimization scheduling method based on a linear programming strategy and tray pre-division, relates to the technical field of milling machine auxiliary tools, and aims to solve the technical problems that a furnace distribution scheme is low in efficiency and a large amount of space and money cost are wasted during production in the existing iron and steel industry. The method comprises the following steps: S1, carrying out quantity statistics on the number of historical fired workpieces in a certain period of time according to volume classification, and dividing frequency partitions; S2, carrying out furnace distribution based on a linear programming strategy, and distributing frequency space on a tray; and S3, based on time greedy, putting the corresponding workpieces into the corresponding partitions for operation. According to the invention, through frequency partitioning and tray pre-division, workpiece production can be reasonably planned in advance, so that the tray space is utilized to the maximum extent, the firing efficiency is improved, furnace distribution workers can conveniently conduct adjustment and other operations on site, and the method has the advantage of industrialization potential.

Description

technical field [0001] The invention relates to the field of iron and steel smelting, in particular to a single-layer furnace matching optimization scheduling method based on linear programming strategy and pallet pre-division, which is mainly used to calculate the appropriate combination and placement sequence for furnace matching among multiple calcined workpieces with different volumes and shapes , used to improve the efficiency of the calciner. Background technique [0002] At present, the plans of most domestic iron and steel enterprises are in the stage of manual compilation, which is inefficient and unscientific. Most of them lack the support of simulation systems and cannot give an objective judgment before production, which brings a lot of production risk. At the same time, in the process of implementing the production plan, there is a lack of comprehensive monitoring and evaluation of the implementation of the plan, and there is a lack of an effective scheduling d...
