Causes of zinc particles on the surface of galvanized strip steel
In the hot-dip galvanizing plate, the surface will often be distributed with small particles. These small particles not only make the galvanized steel surface rough, affecting the overall appearance, but are also harmful to use.
The main reason for the formation of zinc particles is that the bottom slag is floated by excessive mechanical agitation, causing the zinc liquid to adhere to the surface of the galvanized sheet. Alternatively, the temperature of the zinc liquid may be too high, causing...

Shandong 16Mn seamless steel pipe use and classification method_Shandong Seamless Steel Tube Factory
Shandong 16Mn seamless steel pipe use and classification method: Shandong 16Mn seamless steel pipe use: special steel used for bridges is "16Mnq," special steel for automobile girders is "16MnL," and steel for pressure vessels is "16MnR." This steel type improves the mechanical properties of steel by adjusting the amount of carbon (C). According to the carbon content, these steels can be further divided into: low-carbon steels (carbon content is generally less than 0.25%, such as 10, 20 steel),...
How to choose pinhole inspection system for strip steel enterprises
With the increasingly strict quality requirements of steel strip? More and more strip steel production companies are beginning to focus on the quality of the steel strip itself? The surface pinhole is the main defect of the steel strip? Small pinhole holes will seriously affect the quality of strip products? Therefore, it is particularly important to detect pinholes on the surface of the strip. At present, traditional strip steel manufacturing enterprises use human eyes to detect surface...
