The development of an era mainly depends on the various levels of its industrial applications. At present, China's industrial conditions can compete with international standards in all aspects. Whether it is heat treatment equipment, especially for steel enterprises, the effect of hot-dip galvanizing is very important. Because it can also cover a protective layer on the steel, its service life is greatly increased. And in the technical aspect of hot-dip galvanizing, there are naturally some auxiliary things, and the sinking roller is one of the crucial product workpieces.
As we all know, nowadays there are generally two technologies: phosphating treatment and hot-dip galvanizing. And hot-dip galvanizing produces a higher density of metal coverage, without inorganic compound doping, and the coverage level is much better than phosphating treatment. After each steel material is covered with hot-dip galvanizing, it can slow down the time for the steel material to be corroded by the atmosphere, and the surface of hot-dip galvanizing has a special protective film. If it is subjected to atmospheric corrosion, a new protective layer will be formed, which can cause multiple organic chemical reactions and maintenance. Therefore, it is evident that the maintenance force for steel is relatively strong. Nowadays, with the development of high-voltage transmission and communication markets, people's regulations for various steel components are becoming increasingly high. The main reason for the ineffectiveness of cutting machines and drilling holes is that the demand for hot-dip galvanizing is constantly increasing, which in turn makes sinking rollers more critical.
In the field of hot-dip galvanizing, the sinking roller is very important as it generates a continuous production line along with other components. However, these are all very consumable components, and the sinking roller is no exception. At present, the commonly used sinking roller materials in China are all stainless steel materials. After a long period of application, they are not very wear-resistant and are prone to serious damage. Therefore, it has gradually become common to spray a layer of coating on the surface of the sinking roller. This can completely separate the rolling rod from the zinc liquid during hot-dip galvanizing, preventing chemical changes that may cause sinking roller erosion when the two come into immediate contact. Preventing such a situation can greatly improve the quality of hot-dip galvanized building steel, making its surface not very rough. Although sinking rollers may be damaged over time, they have already developed significantly and play an important role in the field of hot-dip galvanizing. They can harm the actual effect of final hot-dip galvanizing and affect the service life of building steel.
The effective effect of the sinking roller is also to set the cross-section of the spiral groove as a V-shaped groove, making the opening of the spiral groove smaller and the bottom larger, which is beneficial for the storage of zinc material in the spiral groove and the fluidity of the zinc material in the spiral groove. This utility model patent prevents the formation of zinc rings, improves the service life of the sinking roller, reduces the consumption of zinc materials, and enhances the quality of hot-dip galvanizing. number. The outer wall of the spiral groove is connected to the outer surface of the roller according to the convex arc structure. Under the separation effect of convex arc structure, zinc liquid can enter the spiral groove. In addition, the bottom of the spiral groove is connected to the outer wall of the spiral groove according to the concave arc structure, further promoting the fluidity of zinc in the spiral groove.
