Control method and control device for steel raw material yard logistics transmission equipment

Abstract

A control method and a control device for steel raw material yard logistics transmission equipment belong to the technical field of steel raw material production logistics. The control method includes the steps: describing a technical process and determining constraint conditions of the technical process by the aid of process data and control data during transmission of a conveyor belt; calculating raw materials conveyed by the conveyor belt at different time in order to minimize tardiness cost; and issuing results to a secondary process control system to control the logistics transmission equipment. The method is used for scientifically and quantitatively describing process features of the steel raw material transmission equipment during control, and controlling the transmission equipment by means of intelligent optimization algorithm based on description, so that a raw material transmission production system is in optimal operating state, the problems of interruption of raw material supply and the like caused by unreasonable distribution are avoided to a large extent, stable operation of the equipment is ensured, production is balanced, the utilization rate of the equipment is increased, production cycle is shortened, and production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of iron and steel raw material production logistics, and in particular relates to a control method and device for iron and steel raw material field logistics transmission equipment. Background technique [0002] Conveyor belt (belt conveyor) is an important transmission equipment in the production process of steel industry, and its function is to allow materials to be transported to the designated destination continuously and uninterrupted. The logistics transmission equipment in the iron and steel raw material yard mainly includes the conveyor belt and its supporting transfer station. The transportation process mainly includes two stages: one is that the conveyor belt transports the raw materials from the dock to the stockyard for storage and processing; the other is that the raw materials are transported from the stockyard to the Blast furnace, sintering and other production workshops. Conveyor belts unde...

[0007] 3) Due to the particularity of the downstream process, the arrival time of the transported raw materials has relatively strict restrictions. If it arrives at the storage tank too early, there may be nowhere to store it. If it arrives too late, it will affect the normal production of the downstream process. cause significant economic losses;

[0009] At present, the control of conveyor belt transmission in large iron and steel plants in my country is still in the stage of manual coordination. Although the operators have rich experience in allocation, due to the constraints of many types of raw materials, large quantities, and unstable incoming materials in the stockyard, manual coordination will inevitably lead to unsatisfactory results. The phenomenon of reasonable transportation causes waste of energy and resources, and even leads to production accidents
