Control method of intelligent supplying system of crude fuel on blast furnace groove

Abstract

The invention provides a control method of an intelligent supplying system of crude fuel on a blast furnace groove, comprising the following steps of: (S1) calculating a target bin of a discharging car by comparing level values of all bins; (S2) when the discharging car is discharged, leading the discharging car to periodically walk backwards and forwards on a corresponding limited position of a limit sensor of the same bin by using a time method; and (S3) carrying out corresponding treatment according to the conditions of all the bins. The invention is capable of realizing the full-automaticmultiple-peak discharge of the discharging car, safe protection and emergency treatment under the conditions of sensor failure, and the like and the commonality and the applicability of an automatic control strategy of the discharging car under the conditions of arbitrary sensor faults and arbitrary bin faults and ensures the anterograde supply of the crude fuel and the material preparing capacity of the bins.

Description

technical field [0001] The invention belongs to the control field of a raw material and fuel supply system on a blast furnace tank, and in particular relates to a fully automatic intelligent control strategy for a raw material and fuel supply system on a blast furnace tank. Background technique [0002] The feeding system above the blast furnace trough is an important part of the blast furnace raw fuel supply process. It undertakes the key tasks of providing raw materials for the batching system under the blast furnace trough and storing raw materials and fuel materials for blast furnace smelting. High utilization factor is closely related. Once there is a problem in the feeding system on the trough and it cannot be dealt with in a timely and reasonable manner, it will seriously threaten the production of the blast furnace and cause huge economic losses. Therefore, the research and application of the fully automatic intelligent control technology for the upper feeding syste...

Problems solved by technology

[0003] At present, the feeding system and its control method on the blast furnace trough have the following problems: most of the unloading trucks are manually controlled by a computer, that is, the operator selects the unloading warehouse, and the trolley will go to the warehouse for unloading, and the manual The operation greatly increases the labor intensity of the workers, and at the same time, it is easy to cause production accidents such as material loss and overflow, which will affect the smooth operation of the feeding system on the trough; most unloading trucks use a single-peak material distribution method, and the material surface in the silo is uneven, which affects the feeding system. The volume ratio of the silo cannot guarantee the material preparation capacity of the silo under special circumstances such as the maintenance of the feeding line equipment; the safety control strategy of the unloading vehicle is relatively simple and not perfect, and the remote control safety of the unloading vehicle cannot be guaranteed under special circumstances
