The process of hot -dip galvanized processing process is relatively complicated, and the time used in processing is relatively long. Generally, the quality of the processing process of complex processing processes is also very different. How can I improve the quality of hot -dip galvanized processing? This has become a concern for many people:
First of all, when the seamless tube is processed by hot -dip galvanized, it will use cold water to cool in cold water after hot galvanizing. The cold water here is generally tap water. During the cooling process, we need to pay attention to the quickly cool down after the steel part is out of the pan. We must not delay at all, so as to ensure that the steel parts will not deform. Some people may complain that the processing workpiece is easy to deform, which may be determined by the speed of cooling.
Secondly, in the hot -dip galvanized processing, we must also optimistic about the temperature of the water. Generally speaking, the temperature of the water should be maintained between 30 degrees and seventy degrees. At the same time, we need to increase the gloss of steel parts in water.
Standards for galvanized seamless pipes:
The hot-dip galvanized standard references GB/T13912-2002, metal coverage layer, and technical requirements for hot-dip galvanized layer of steel parts.
The production step of galvanized steel pipe
The process process is: black tube -alkaline washing -water washing -pickling -water drift -immersion -drying -hot immersion galvanized -external blow -air -cooled -water cooling -water cooling --Prillida -Rinse of Water -Test -Weight -Enter the warehouse.
