1ton/hour Hot dip galvanizing furnace variable frequency temperature regulation for fasteners screws nuts nails
1. widely used fields of hot dip galvanizing furnaces
HDG furnace are widely used in various industries such as construction, automobiles, ships, furniture,
electricity,transportation, and communication. Metal products in these industries often need to withstand
harsh environmental conditions,so galvanizing has become an important anti-corrosion method.
2. Equipment overview
2.1The hot dip galvanizing furnace immerses metal products in molten zinc to form a uniform layer of zinc
on the surface of the metal.This layer of zinc can effectively resist the erosion of atmosphere, moisture, and
chemicals, thereby extending the service life of metal products.In the construction industry, galvanized steel
is widely used in building structures, pipelines, steel beams, etc. to improve their weather resistance and corrosion
resistance.In the automotive industry, galvanized parts can resist corrosion from road salt spray and humid environments,
thereby extending the service life of cars.In the shipbuilding industry, galvanized components can resist the corrosion of
seawater and improve the durability of ships.

2.3Zinc kettle heating equipment heating rod
2.3.1Zinc galvanizing furnace efficient and energy-saving design:
Special hot-dip galvanized heating wire
SSR module integration
2.3.2Intelligent control technology:
High precision PID temperature control
Deep reinforcement learning optimization control
Transfer learning furnace temperature prediction algorithm
2.3.3No faults, no maintenance and environmental protection:
Integrated diagnosis and repetitive functions
Continuous power regulation of intelligent instruments.
2.4Electric control
The intelligent temperature control system uses PID calculation and automatic adjustment of the temperature
control system to ensure that the heating temperature is controlled within ± 2 degrees, meeting the process
temperature requirements of hot-dip galvanizing heating equipment. The system equipment has functions such as
digital current display, automatic temperature control display, and is equipped with leakage protection devices and
over temperature alarm devices. Temperature detection uses high-precision temperature control instruments and
signals from different temperature sensors to detect and provide feedback to intelligent temperature control instruments.
The instrument adopts fuzzy rules for PID regulation, which has the characteristics of no overshoot and high precision.
The system is well-designed, highly automated, safe and reliable, and suitable for a wide range of industrial applications.
