Simulation method for continuous casting and rolling steel making plan

Abstract

The invention relates to the technical field of simulation, and discloses a simulation method for a continuous casting and rolling steel making plan. The simulation method comprises the steps of first, calculating earliest time of ironing in each furnace plan of each cast plan, sorting each of the furnace plans in each of the cast plans according to the earliest time of ironing in each of the furnace plans, then, adding up a handling time of a following process to a recursion of the earliest time of ironing in each furnace plan, obtaining earliest permitted operation time of each of the processes in each of the furnace plans in each of the cast planes, and obtaining simulation results. According to the simulation method for the continuous casting and rolling steel making plan, a high match between a steel making plan and a rolling plan is achieved, a limited condition requirement of a steel-making process of the continuous casting and rolling is satisfied, implementation rate of production plans and production efficiency are improved, and therefore manufacturing cost is reduced. The simulation method is reasonable in structure, remarkable in effect and strong in practicability.

Description

technical field [0001] The invention relates to the technical field of simulation, and is mainly applicable to a simulation method for continuous casting and rolling steelmaking plans. Background technique [0002] The continuous casting and rolling production process closely connects the important production processes from molten iron to hot-rolled coils such as smelting, casting, heating, and rolling. Any problem in any process will have serious consequences for the arrangement and execution of the production plan of the entire production line. influences. The four major processes are rigidly connected, but there is a very small buffer between the refining and heating processes. [0003] At present, the production characteristics of the main domestic continuous casting and rolling production lines are to organize production in an inventory-oriented manner, with a single product variety and specification; It is just a pre-plan, only the rolling specification and rolling s...

Problems solved by technology

To achieve this, a high degree of matching between the steelmaking plan and the rolling plan is required, but it is difficult to achieve a high degree of matching between the steelmaking plan and the rolling plan in the information system
