Qingdao Hexin Machinery Co., Ltd fabricated various designs of galvanizing kettles, zinc pots for galvanizing lines.

We manufacture zinc pots with strict production procedures and rules,the manufacturing material of galvanizing pot is made of special steel for zinc pot. Approved special material for zinc pots.

In order to ensure the quality and service life of the zinc pot, we are very serious about the production process. Our company re-checks the chemical composition of the incoming steel plates one by one. 

The company strictly implements GB/T11345-1989 and other relevant national standards. 100% ultrasonic flaw detection; use the plate width to reduce the length of the weld,

Avoid the heating area, change the position of the weld according to the user's requirements and the characteristics of the kiln, and the finished galvanized pot will pass the ultrasonic flaw detection of the weld.


The main equipment of the hot-dip galvanizing furnace includes: galvanizing pot, galvanizing furnace body, heating system, temperature measurement and temperature control system. The selection of materials related to this, 

the quality of manufacturing and processing technology, the selection of heating system and its combination with the zinc pot, the accuracy and reliability of temperature measurement and control equipment, etc., 

all directly affect the life of the zinc pot and the entire galvanizing process. cost and efficiency.

Different heating systems have been developed to adapt to different energy sources such as gas (natural gas, city gas, etc.), electricity, oil and coal. The manufacturing, installation and heating characteristics of the heating system 

have a great influence on the life of the zinc pot.

The furnace structure and combustion system should make full use of the available heating area of ​​the zinc pot to provide uniform heating to the pot wall. , to avoid hot spots on the pot wall to prolong the life of the zinc pot.

Some people argue that the heating system of the galvanizing furnace should transfer most of the heat to the upper half of the zinc pot, because the upper half of the zinc pot is the part that consumes the most heat during hot-dip galvanizing.

However, in this way, the zinc pot should be deep enough and the heating area of ​​the zinc pot should be large enough to ensure that the upper half of the zinc pot does not exceed the critical heating intensity. 

The lowest part of the heating surface of the zinc pot must be kept at about 100mm above the zinc slag layer. If it is estimated that the zinc slag layer can reach about 200mm,

 the zinc pot should not be heated within 300mm above the bottom of the zinc pot.

The control of the furnace temperature of the galvanizing furnace is also very important to prolong the life of the zinc pot. In addition to uniform heating, 

the temperature difference between the inside and outside of the zinc pot must be minimized, and the temperature of the inner wall of the zinc pot cannot exceed 480°C.
