Problems solved by technology

[0005] 1. The implementation of the rolling plan is limited by the strict order of loading materials according to the slab, so it is difficult to adjust the production plan on demand
[0006] 2. Strictly load materials in sequence, increase unnecessary slab inverting operations, increase the workload of slab warehouse equipment, and cause the production line to wait for materials
[0007] 3. If the production conditions cannot be loaded according to the sequence of the rolling sequence, the planner must re-program the rolling sequence to increase the workload of the planner
[0008] 4. It is impossible to compile a rolling plan for the slab that has not yet been produced but will be produced soon, which is not conducive to the production organization of hot delivery and hot loading between steelmaking and hot rolling, and direct loading

Abstract

The invention discloses a hot rolling roll period planning method. The method comprises the steps that first electronic equipment establishes M virtual slabs according to information of the requirements for slabs of an order, wherein the M virtual slabs correspond to M virtual slab numbers respectively, M is a positive integer, and the information of the requirements for the slabs of the order comprises the requirement for the slab steel grade of the order, the requirement for slab specifications of the order, the requirement for slab surfaces of the order and the requirement for slab quantity of the order; the first electronic equipment performs permutation and combination on the M virtual slabs according to hot rolling rules and establishes a material preparation plan, wherein the material preparation plan contains the M virtual slab numbers; the first electronic equipment transmits the material preparation plan to second electronic equipment.

Description

technical field [0001] The invention relates to the technical field of hot rolling of iron and steel, in particular to a method for preparing a roll schedule plan for hot rolling. Background technique [0002] The hot rolling production operation planning and scheduling in the iron and steel industry is the link between the production organization of the steelmaking plant and the hot rolling plant. [0003] Since the preparation of hot rolling production plan requires strict combination of rolling material thickness and width jump rules to form a "coffin-shaped" sequence, and taking into account the user's surface quality requirements, hot hardness of the product during rolling, and wear of the roll, etc., the production operation plan (rolling system), while the slab stacking in the slab warehouse is multi-layer stacking (generally 12 or 14 layers). In the process of executing the production operation plan in the slab warehouse, the slab loading must be lifted from top to ...
