Embodiment Construction

[0063] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0064] A method for precise allocation of slab resources in iron and steel enterprises, such as figure 1 shown, including the following steps:

[0065] Step 1: Group the non-entrusted slabs and contracts in the hot rolling front warehouse of iron and steel enterprises according to the steel grade, and obtain multiple non-entrusted slab contract groups. The specific steps are as follows figure 2 shown;

[0066] Step 1.1: Make the steel grade subset g=1, select a steel grade from the steel grade set, and delete it from the steel grade set, put the steel grade into the steel grade subset g, if the steel grade set If it is empty, go to step 1.4, otherwise go to step 1.2;

[0067] Step 1.2: From the steel grade set, select the steel grade that has a steel grade superiority relationship with the steel grade in the steel grade subs...

Abstract

The invention provides an accurate distribution method for slab resources of an iron and steel enterprise. The method comprises the steps that hot rolling front-warehouse non-order slabs of the iron and steel enterprise and contracts are grouped; the distribution relation of the slabs and the contracts in each non-order slab contract set is judged; the distribution cost goal constraint of the non-order labs and the contracts is calculated; the non-order slabs are distributed to the contracts, and a non-order slab and contract distribution scheme is formed; the non-order slabs which are not included in the non-order slab and contract distribution scheme are clustered to form a virtual contract generating scheme, and the virtual contract generating scheme is issued to a manufacturing execution system of the iron and steel enterprise. The problems that due to the fact that the non-order slabs in the iron and steel enterprise are high in inventory and low in utilization rate, inventory cost is high, and the slab shear amount is large are solved, the utilization rate of the non-order slabs is improved, meanwhile, a large amount of energy waste caused by repeated steelmaking is reduced, the shear amount and inventory of the slabs are reduced, and a large amount of production and storage cost is saved for the enterprise.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a method for accurately allocating slab resources in iron and steel enterprises. Background technique [0002] The technological process of iron and steel enterprises is divided into four areas: iron-making area, steel-making area, casting area and steel-rolling area. (2) In the steelmaking area, the molten iron is smelted by the converter and refined outside the furnace to form molten steel, and the raw materials are produced during the production process. (3) In the casting area, casting methods are divided into continuous casting and mold casting. On the one hand, molten steel is cast into slabs by continuous casting machines and supplied to hot rolling mills; Ingots are supplied to the preliminary rolling mill, and the casting process is to convert liquid raw materials into solid products; (4) The steel rolling area is mainly divided into three sub-areas, na...
