Today, hot-dip galvanized steel pipes are a common type of fire protection pipes, playing an irreplaceable role in the fire safety industry. Why can't hot-dip galvanized pipes be replaced by cheaper welded pipes or cold galvanized pipes? Hot-dip galvanizing was invented in the mid-18th century and developed from hot electrolytic tin plating processing technology. Up to this day, hot-dip galvanizing remains one of the most widely used and effective processing technologies for steel corrosion resistance.
To facilitate slag removal and zinc extraction, 20 tons of lead should be added to the zinc pot.
Preheat the slag extractor before use. Store zinc slag in different sizes. The temperature for slag extraction should be controlled above 455 degree . Use special tools when operating the slag extractor and stand with your feet in a "T" position, one meter away from the zinc pot.
The hot-dip galvanizing process requires strict control. Therefore, during hot-dip galvanizing production, it is necessary to maximize work efficiency. In other words, the more pieces or tons produced per unit time, the lower the cost, and vice versa.
