Embodiment Construction

[0053] Embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art would recognize that the described embodiments can be modified in various ways or combinations thereof without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Also, in this specification, the drawings are not drawn to scale, and like reference numerals denote like parts.

[0054] For the continuous casting secondary cooling system, under normal circumstances, the flow rate of each secondary cooling control circuit has a unique corresponding relationship with the nozzle working pressure (pressure after the valve) of the circuit. Under the target flow rate, when the nozzle or the pipeline behind the valve is blocked, the nozzle is used for too long to cause serious wear, and the pipeline behind the valve leaks, etc., t...

Abstract

The invention discloses an intelligent detection and control method for the online working state of a continuous casting secondary cooling system, comprising: establishing a reference flow-pressure relationship curve; setting the flow rate of the secondary cooling control circuit in the continuous casting secondary cooling system; The relationship curve can be used to obtain the reference working pressure of the nozzle in the secondary cooling control circuit under the set flow rate; under the set flow rate, measure the actual working pressure of the nozzle in the secondary cooling control circuit; compare the actual working pressure with the reference working pressure, According to the comparison result of the working pressure, the working state of the secondary cooling control circuit is obtained. The present invention can realize real-time monitoring of the working state of the continuous casting secondary cooling system, judge whether the continuous casting secondary cooling system is working normally, and improve the accuracy of judging the working state of the continuous casting secondary cooling system, and when an abnormality is found, Send processing suggestions to production engineers in time, so as to improve pouring quality and reduce pouring accidents.

Description

technical field [0001] The invention relates to the technical field of steel billet continuous casting in the iron and steel metallurgy industry, in particular to an intelligent detection and control method for the online working state of a continuous casting secondary cooling system. Background technique [0002] Uniform secondary cooling in steelmaking and continuous casting is a prerequisite for uniform solidification structure of continuous casting slabs, and it is also a key guarantee for continuous casting to obtain continuous casting slabs with conforming dimensions, surface quality and internal quality in continuous casting. In the continuous casting process, the blockage and wear of the nozzle of the continuous casting secondary cooling system, the blockage of the pipeline filter and whether the regulating valve can work normally, and the leakage of the pipeline medium are important signs of whether the secondary cooling working state is normal. At present, the onli...
