Description
Technical Field
The utility model relates to the technical field of plate strip production and treatment.
Background
In the metallurgy industry and other industries, various strip production processing lines are provided, such as a galvanizing line, a color coating line, a tinning line, a continuous annealing line, an aluminum strip and copper strip production line and the like, and similar strip processing lines have important strip cleanliness in the production process, and the cleaner the steel plate surface is required to be when producing and manufacturing high-quality coated steel, galvanized plates or other products.
The surface of a plate of a general metallurgical treatment line contains impurities such as residual oil, residual iron and the like, the surface of a strip steel needs to be cleaned and dried before the plate is subjected to heat treatment or coating, and the final quality of a product is directly influenced by whether the impurities such as the residual oil, the residual iron and the like on the surface of the plate are clean or not. Therefore, the online surface cleanliness of the plate can be effectively detected, and the quality of the final product can be effectively controlled. The cleaning section is adjusted and intervened according to the monitoring of the plate cleaning effect, so that the product quality can be greatly improved, and meanwhile, the consumption of the cleaning section is reduced.
In the actual production process of the plate strip, no mature method is available at present for carrying out effective and rapid online test on the surface cleanliness of the plate strip before and after the surface cleaning treatment process of the plate strip. The conventional methods include a test paper wiping method, a static sampling chemical detection method and the like, and the methods have various defects such as incapability of quantification, extremely high safety risk, detection only after a production line is stopped and the like. Therefore, a safe, reliable and accurate online detection system for the surface cleanliness of the plate strip is urgently needed to complete the work, real-time monitoring is achieved, data are fed back to production line production personnel on line, the production personnel can master the cleanliness of the plate strip at the first time, parameter adjustment can be carried out on the production line in real time through comparison standards, the product quality is efficiently improved, and the cost is effectively saved.

Detailed Description
The wire board surface cleanliness detection system disclosed by the utility model is shown in fig. 2 and comprises a laser 3, a detector 2, a power supply module and a data analysis and processing module, wherein the data analysis and signal processing module is connected with an output display module. The laser 3 is connected with the power supply module, the output signals of the laser 3 and the detector 2 are connected with the data analysis signal processing module, the laser is used for emitting laser to the plate strip 1, and the detector is used for collecting radiation light generated after impurities on the surface of the plate strip are ionized and carrying out spectral analysis.
As shown in fig. 1, in the process of processing the plate strip 1, the surface cleanliness detection is carried out on two sides passing through a strip steel cleaning system 4 through a laser and a detector respectively. By utilizing a laser technology, a beam of high-energy-density pulse laser is emitted to be shot on the surface of the plate strip, common pollutants on the plate strip, such as metal oxide, metal powder, oil stain and water, are rapidly heated and ablated under the irradiation of the laser, and the plasma state is achieved. The plasma radiates optical signals to the air, the wavelength and the frequency of the signals are obviously different from those of pulse laser used for ablation, the intensity and the spectrum of the radiated optical signals have strong correlation with surface pollutants, the radiated optical signals are analyzed and calculated through the detector, the cleanliness of the surface of the plate strip can be judged, data are transmitted to the analysis system, the analysis system analyzes and calculates, and the detection result is output and displayed through the output display module.
