The service life of a zinc kettle is affected by a number of factors, including the material of the zinc kettle, the manufacturing process, the operating conditions, and the state of maintenance. Here are some points of information about the service life of zinc bath:
Material:
Earlier zinc kettles may have used 08F steel as the material, while nowadays it is more preferable to use imported WKS plates or specialized steel plates like XG08, which have lower carbon, silicon, manganese, phosphorus, and sulfur content and are effective in resisting corrosion by zinc liquid.
Some zinc kettles may use high resistance flat belt heating elements arranged around the zinc kettle with low power heating elements at the bottom, in this configuration the life of the heating module is about 2-3 years compared to about 3-5 years for metal zinc kettles.
Production process:
Prior to initial zinc melting, the inside of the zinc pot is coated with a 1.0 to 1.5 mm thick layer of zinc-resistant BGF-type paint to enhance corrosion resistance.
The heating process of the zinc pot needs to be strictly controlled to avoid localized high temperature damage to the pot wall.
Operating conditions:
The temperature of the zinc solution, the frequency of use of the zinc pot, and the level of impurities in the zinc solution will affect the life of the zinc pot.
Temperature management of the zinc pot, if the temperature of the zinc pot is too high, it will accelerate the corrosion and aging of the zinc pot.
Maintenance:
Regularly clean the zinc slag at the bottom of the zinc pot, because the accumulation of zinc slag will lead to uneven heat distribution and increase the risk of localized corrosion.
Correct installation, proper use and maintenance have a significant impact on the service life of the zinc pot.
Depending on the report, the service life of a zinc pan can vary from a few months to several years:
Domestic hot-dip galvanized pans typically have a service life of between 3 months and 2 years.
Zinc pans using specialized materials such as XG08 steel sheet may have a longer service life due to better corrosion resistance.
In some cases, the service life of a zinc pan can be more than 8 years.
In order to improve the service life of zinc pots and pans, research and practice have been going on in the industry, including improving materials, optimizing design, upgrading maintenance techniques and operating practices. The use of induction zinc pots is also gaining popularity, as they offer the advantages of higher thermal efficiency, less bottom slag generation, more stable zinc liquid temperature and longer service life. The replacement cycle of the induction body (heater) of an induction zinc pot may be around 5 to 10 years, which reflects the longer life of the entire zinc pot system.
