Problems solved by technology

[0006] 1) The effective utilization rate of continuous casting slabs is low, and the effective slabs produce products outside the order contract;
[0007] 2) Large changes in order specifications lead to large changes in production planning specifications, increasing production difficulty and affecting production line process control capabilities
[0008] 3) The increase in the quantity of unplanned products attached to the contract not only occupies the inventory, but also seriously affects the completion rate of the contract;
[0009] Unplanned products attached to the contract are sold at low prices, affecting economic benefits

Embodiment 1

[0025] Example 1 (manual design of one slab with multiple orders)

[0026] Order No.: QA111040127-19, order size 14×2000×12000mm, weight 2.638t; order number: OA111040093-16, order size 14×2000×9000mm, weight 3.956t (need 2 pieces); order number: QA111040047- 15. The order specification is 14×2000×9000mm and the weight is 1.978t. The specific process is as follows:

[0027] (1) Medium plate rolling process management - HMI slab design, query all small batch (within 10t) orders, and sort by thickness;

[0028] (2) Select the above 3 order numbers, and insert them into the blank group design from long to short;

[0029] (3) Waiting for drawing production.

Embodiment 2

[0030] Example 2 (replacement of spare blanks instead of manual one blank multi-order slab design)

[0031] Order No.: OA111030031-11, order specification is 24×1800×8000mm, weight 2.764t (1 piece); order number: OB111030021-16, order specification is 24×1600×8000mm, weight 2.457t (1 piece). The specific process is as follows:

[0032] (1) Query the remaining slabs, select the slab number 1110242336, and the specification 220×2060×1681;

[0033] (2) Medium plate rolling process management - HMI spare billet replacement screen, query all small batch orders, and sort by thickness;

[0034] (3) Select the above 2 order numbers, and put them into the blank group design from long to short;

[0035] (4) Furnace production of remaining blanks.

[0036] The invention carries out one billet multi-order billet assembly, improves the effective utilization rate of billets, reduces the unplanned products attached to the output contract, optimizes the production plan at the same time, in...

Abstract

The invention discloses a steel plate production method based on an MES management system. In the method, assembly production is performed according to the number of actually required steel plates of all orders, and on the premise of the same steel variety and thickness, orders left after large order assembly and small-assembly orders are combined and assembled to realize the 100-percent assembly and feeding production of the assembly materials and orders. The method improves the effective utilization rate of assembly materials, reduce production of unplanned products attached in contracts, optimize production plan, increase weight of assembly materials and realize high-efficiency production of a production line.

Description

technical field [0001] The invention belongs to the field of metallurgy, and relates to a method for forming a blank, in particular to a production method for forming a blank based on an MES management system. Background technique [0002] With the fierce competition in the medium and heavy plate market, the market demand is personalized, and the number of small batch orders has increased significantly. In order to meet market demand and benefit needs, small batch order production has become a major issue in the organization of production in various rolling mills. At present, the organization of small batch order production is mainly in the following forms: [0003] According to the product specifications of each order, the billets of the same order and the same specification are assembled for production. If the size of the billets does not reach the lower limit of furnace loading, the number of pieces of this specification for the order will be increased to carry out the b...
