Steel has the advantages of high strength, good plasticity, good process performance, easy processing, etc., so it is widely used in industrial production. However, steel in the process or use process if encountered in the wet environment prone to rust and corrosion, which will reduce the quality of the metal, affecting its service life. In order to ensure the performance advantages of steel as a raw material, it is important to remove rust and contaminants from its surface. Currently for the steel rust removal and cleaning needs, laser cleaning machine is increasingly popular in the market.
Laser cleaning process is a new type of industrial cleaning developed in recent years. It uses the vibration of the laser pulse, the thermal expansion of the particles, molecular photolysis of the three effects to overcome the bond between the pollutant and the material surface, so that the rust, coating, etc. from the material surface, so as to achieve the purpose of cleaning. Laser cleaning rust on the steel surface has the advantages of good rust removal effect, high control accuracy, low operating cost, safety and environmental protection. The emergence of laser cleaning machine is an innovation and enhancement of traditional cleaning equipment, which can avoid the disadvantages of conventional cleaning which is not ideal or traditional cleaning with large pollution.
Laser cleaning machine in the steel manufacturing applications
1. Steel laser cutting pretreatment
Steel processing is inseparable from the important process of cutting, of which laser cutting has become the most common method of steel cutting. However, when laser cutting steel, the final cut quality is affected by the cleanliness of the material surface. If the surface of the steel is rusty or has some contaminants such as oil, then it may cause problems such as the cut section is not smooth. In order to ensure that the steel is cut to a higher quality, the surface needs to be cleaned and removed of other contaminants such as rust before processing. This way the cut workpiece can be used directly in the next process and provide its own performance advantages for the next product manufacturing.
2. Steel welding pretreatment
The surface cleanliness of the metal before welding will directly affect the quality of the weld and the solidity of the weld. Using laser cleaning machine to clean the surface of the steel plate before welding can effectively ensure the quality of welding.
3. Steel cleaning after welding
In the welding of steel plates, especially the traditional welding process, after welding will often appear on the surface of the material impurities or oxide layer, seriously affecting the later beautification process. The use of laser cleaning machine can efficiently clean the weld oxide, impurities, oil stains, and does not damage the weld base material, can effectively ensure the quality of subsequent processing.
4. Steel surface coating pretreatment
In many cases, manufacturers need to brush coating on the steel surface to improve its corrosion resistance or improve the aesthetics. If there are contaminants on the surface of the material before the coating is started, it will affect the adhesion of the paint and cause the paint to peel off easily. Therefore, the steel plate that needs to be brushed with coating should be cleaned on the surface first to ensure that the surface is clean and free of contamination so that the coating can have higher adhesion.
This shows that laser cleaning machine is widely used in steel manufacturing. In addition to the efficiency and accuracy of laser cleaning, it also has other more advantages is the reason for its popularity. Most of the fiber laser cleaners on the market today are designed with a handheld laser cleaning gun, the operator only needs to hold the handle, the laser gun to the surface of the material to be cleaned to scan back and forth, you can remove the material surface contaminants at high speed. And laser cleaning machine can be used by power, no other consumables, operating costs are also very low.
Fiber laser cleaning machine in the removal of rust, paint, oil and other pollutants removal has irreplaceable advantages, whether it is the pre-treatment of steel plates or finished metal cleaning, laser cleaning machine can bring good results.
