Embodiment 1
[0020] In order to make the present invention clearer, a method for fault diagnosis and alarm of rolling mill equipment of the present invention will be further described below. The specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.
[0021] Such as figure 1 As shown, taking the steel rolling process of the medium plate rolling mill as an example, the medium plate rolling mill is composed of two reversible four-high rolling mills. The high-pressure water descaling removes the primary oxide slag, and then it is transported to the preliminary rolling mill to realize the preliminary rolling stage; then, it is transported to the intermediate roller table for cooling, and after reaching the starting rolling temperature of the finishing mill, it enters the finishing mill for secondary rolling until to the finished product thickness. Finally, it is transported to the pre-leveling machine for straig...

The invention relates to an equipment fault diagnosis and alarm method for a rolling mill. The method comprises the specific steps that firstly, zoning processing is conducted on field equipment; then, according to zones formed after division, the states of all the equipment in the zones are connected into programmable logic controllers (PLCs); then, an industrial personal computer is in communication connection with all the PLCs, and monitoring control software is installed on the industrial personal computer to display the states and historical alarm records of the equipment; then, all faults are summarized in the PLCs to trigger a duty room alarm device; and finally, an operator on duty confirms alarm zones according to computer pictures and clicks on the corresponding zones to identifyfaulty equipment so that the identified equipment faults can be correspondingly processed. The method has the advantages that the fault time is greatly shortened, accidental fault hidden dangers arefound in time through historical fault records, predictive maintenance is achieved, and the production efficiency is greatly improved.
Description
technical field [0001] The invention relates to the technical field of metallurgy, in particular to a method for fault diagnosis and alarm of rolling mill equipment. Background technique [0002] For continuous production enterprises, equipment failure has a great impact on operating rate and output. When a fault occurs, it takes time and effort for the maintenance personnel to find the fault, and the information transmission is not timely. All kinds of faults affect the performance of the equipment itself at the same time, which invisibly increases the maintenance cost of the equipment. Contents of the invention [0003] The purpose of the present invention is to solve the problem of untimely fault diagnosis and low efficiency of the existing rolling mill equipment, and provide a method for fault diagnosis and alarm of rolling mill equipment, which can greatly reduce the fault time and timely detect accidental faults through fault history records. Prevent permanent failu...
