Equipment Briefing

Hessing provides galvanizing plant for hot dip galvanizing of any kind of irregular structural steel products of different shape and dimensions. The galvanizing hoist can be designed with circular rail or liner rail.
The furnace is the central part of the galvanizing plant, The accurate temperature guarantees the good coating quality, the heat efficiency can reach 75% which is very important for cost competitiveness. Even heating furnace can extend the lifetime of the zinc kettle. Specially designed hoists run and stop steadily, minimize the swing distance of the workpiece. The emission treatment equipment as requested by the customers can meet the requirements of international standards.
The max. Dimension of zinc kettle (m)： 16 x 2.6 x 3.6

Main Equipment 

1. Enclosed pre-treatment equipment with acid proof tanks 
○ Latest materials and technology for environmental protection 
○ Acid resistance treatment for the full construction 
○ Controlled air flow to maintain negative internal pressure 
○ System designed to work automatically with the scrubber. 
○ Hoists with he workpiece run according to the process inside the enclosure. 

2. Drying equipment 
○ Reduce the happenings of zinc blast, and less zinc consumption 
○ By making full use of the recycled heat, the workpieces get the proper temperature before dipping into the zinc kettle, less dipping time is needed, the capacity efficiency is increased. 
○ Heat circulation blower is adopted, it gives even temperature inside the drying furnace. 

3. Heating furnace 
○ World-class technology in heat transfer design in the furnace, widely used in more than 200 projects 
○ Good insulation and fuel saving. 
○ Uniform temperature inside the furnace. Even heating of the zinc kettle is key to extend the zinc kettle lifetime. 
○ Quick response to the temperature control, high efficiency and economical operation. 
○ The kettle change is simply and convenient, low furnace maintenance cost. 

4. Zinc kettle 
○ The kettle plate is made specially for liquid zinc, low carbon and silicon, corrosion proof 
○ Professional welding skills, the lifetime of the welding seam is longer than the mother steel plate 
○ Various zinc kettle geometric structures, different steel plate thickness, accurate dimensions. 

Supporting Equipment

1. Acid storage and supply equipment 
○ Option with vertical and horizontal acid tank. 
○ Acid pump fulfills the task to transfer the acid between the acid tank and the acid baths. 
○ No leakage, safety and environmental friendly. 

2. Acid collection and scrubber 
○ Good sealing of the acid pipelines and the acid mist blower, no leakage. 
○ Automatic alkaline feeding and PH value checking
○ Multiple level alkaline spray, fully neutralization reaction of the acid mist. 

3. Zinc smoke/dust collection and treatment equipment 
○ Good seal of the dust suction hood, pipeline and the blower, no leakage. 
○ The filter cloth has good performance to stop the dust particles, the particle discharge can reach the required domestic and overseas clean air standards. 
○ The blower running speed is adjusted automatically according to the concentration of the dust particles, electricity cost is optimized. 

4. Waste heat recovery boiler 
○ The tail waste heat from the zinc kettle heating furnace is fully utilized, energy consumption is optimized. 
○ High temperature steam is generated from the boiler for good performance of the inner blow. 
○ Automatic control, no special guardian needed.

5. Deironing separator from Fluxing chemical
○ Continuous operation, good performance of deironing
○ Automatic control, no special guardian needed

6. Zinc pump 
○ Big flow capacity, long lifetime and easy operation.

7. Zinc dross filter 
○ Thorough cleaning of the zinc dross, no blind angle inside the zinc kettle, easy operation.
