Since steel is easy to rust or even completely damaged in air, water or soil, the annual loss of steel due to corrosion accounts for about 1/10 of the entire steel production. Therefore, some method is required to protect steel from corrosion. The batch hot-dip galvanizing production line is an intelligent and efficient production line for batch processing of steel.


Ritman intelligent batch hot-dip galvanizing production line consists of black parts pendant area, automatic pre-treatment area, automatic circulation galvanizing area, automatic cooling-passivation-discharging area, and hot-dip galvanizing environmental protection equipment area. The environmental protection equipment area includes automatic heating system for waste heat from flue gas, cooling water cooling system for high temperature cooling tower, special bag filter for hot-dip galvanizing flue gas, all-in-one machine for additives (the treated auxiliary waste liquid can be directly reused), and rinsing water It is composed of processing integrated machine, pump room + pipe gallery automatic control liquid level replenishment, secondary acid mist spray tower, and main control room.


The application scope of hot-dip galvanizing has also expanded correspondingly with the development of industry and agriculture. Therefore, hot-dip galvanized products are widely used in technology (such as chemical equipment, petroleum processing, marine exploration, metal structure, power transmission, shipbuilding, etc.), agriculture (such as sprinkler irrigation, greenhouse), construction (such as water and gas transmission, wire casing, scaffolding, Housing, etc.), bridges, transportation, etc., have been widely used in recent years. Because hot-dip galvanized products have the advantages of beautiful appearance, anti-corrosion, low cost, etc., their application scope is more and more extensive.

Case: Smart Scaffolding Hot-Dip Galvanizing Line

Production Line Layout: General Floor Plan


The length, width and depth of the zinc pot of this production line are: 5*2*3.2 meters (or 6*2.4*3.4), and L-shaped hot-dip galvanizing production line can be realized in one workshop; 8-10 hangings can be realized per hour It is mainly used for hot-dip galvanizing of small pieces of iron towers, connecting plates, tower feet, etc., with lower zinc consumption, gas consumption of 10 cubic meters/ton, power consumption of 10 kWh/ton, and the daily output of small pieces reaches 200 tons.


Composition of Production Line

1)  Raw parts loading area

Three spans for raw part loading area  with total 6 loading position were reserved to ensure 7-8 dips per hour.

Equipment includes lifts, automatic ground rail vehicle and overhead cranes.

2) Pre-treatment area

It Includes micro-negative pressure enclosure, process tanks, pump station for automatic regulation, aeration system for improving pickling quality, reductioin tank, rinsing tank and flux tank, automatic RGVs and constrol systems. The raw parts will go through various processes with the help of RGVs.

3) Secondary inspection area

The secondary inspection area composes of the inspection platform, inspection supports and commonly used treatment equipment. It is mainly used for secondary hanging, rack changing for galvanizing and inspection of pickling quality.

4) Galvanizing area

This area is used for hot-dip galvanizing and composes of furnace, galvanizing kettle, end-in to side-out type galvanizing hood and RGVs.

5) Cooling and deactivation area

This area is used for automatic cooling and deactivation of galvanized parts and composes of cooling tank and deactivation tank.

6) Unloading and trimming area

This area is used for trimming and packing of galvanized parts and composes of unloading lifts, trimming platform and trimming tools.

7) Environmental equipment area

This area composes of bag filter, scrubber, automatic treatment equipment for rinsing water, automatic treatment equipment for flux, integrated treatment equipment for degreasing water and waste acid treatment equipment for PFC.
