Product Description
CE Automatic Pulse Heating Galvanizing Furnace System for Zinc Tank Line
Product Overview

This CE automatic pulse heating galvanizing furnace system is designed for industrial hot-dip galvanizing lines requiring stable zinc bath temperature control, uniform heat distribution, and continuous production reliability.

The system combines a zinc kettle structure, pulse combustion furnace, dual-zone thermal regulation, exhaust heat recovery, and PLC automation control. It is suitable for large-scale galvanizing production environments with flexible tank dimensions and high thermal load demand.

Typical engineering configuration supports zinc tanks such as 7000 *1200*2200 mm (L*W*D) and furnace bodies around 9000 *3200*1800 mm, depending on production capacity and line layout.

Thermal Stability & Process Challenges

In conventional galvanizing heating systems, process instability mainly comes from:

IssueTechnical Impact
Temperature inertiaSlow response → overshoot/undershoot of zinc bath temperature
Uneven furnace heatingLocal overheating → inconsistent coating quality
No heat recoveryHigh fuel consumption and energy waste
Weak process visibilityLimited real-time monitoring of furnace conditions
Thermal stress accumulationReduced service life of zinc kettle structure
Integrated Engineering Design

The system is engineered around closed-loop thermal control and energy optimization:
