The high-frequency heating principle at the core of this system enables efficient, non-contact energy transfer directly to metal tube materials through electromagnetic induction. This method achieves rapid temperature rise with minimal energy loss to the surrounding environment, making it both thermally efficient and operationally safe for production line integration. Each complete system is assembled and comprehensively tested in our Zhaoqing manufacturing facility across six dedicated production departments before customer delivery.
System Overview

Industry Applications
This High Frequency Heating Annealing System serves production requirements across multiple tube manufacturing sectors:
Tube Shrinking Lines: Integrated into tube diameter reduction production lines, the system provides intermediate annealing when work-hardened tubes reach their compression limit. By softening the tube material at key stages, the heating system enables continued shrinking to achieve target diameters without material cracking or structural degradation.
Tube Bending Work Cells: Deployed as pre-bending heat treatment stations, the system delivers controlled annealing that prepares tubes for bending operations. Proper pre-heating reduces forming forces, minimizes spring-back effects, and prevents stress cracking during the bending process for higher quality finished components.
Cable Manufacturing Facilities: In cable production plants, the system processes metal conduit and armor tubes as part of complete cable protection component manufacturing lines. The high-frequency heating ensures consistent material properties for reliable cable protection performance in finished products.
Electrical Appliance Production: For household appliance manufacturers, the system anneals heating element tubes before forming operations. The precise heating control preserves the thermal performance characteristics of heating element materials while enabling the forming required for water heater, oven, and other appliance heating components.

FAQs
Q: How does high-frequency heating achieve the annealing effect in metal tubes?
A: High-frequency heating uses electromagnetic induction to transfer energy directly into the metal tube material, causing rapid and uniform temperature rise throughout the tube wall. This controlled heating softens the metal microstructure, reducing hardness and increasing ductility. The induction method delivers heat efficiently and uniformly around the tube circumference, producing consistent annealing results without contact heating elements that could cause surface damage or uneven treatment.
Q: What utility connections does the complete heating system require?
A: The High Frequency Heating Annealing System requires a three-phase 380V electrical supply and 0.6Mpa compressed air connection for operation. The system's heating power output is adjustable across a 35-45KW range, allowing operators to match heating intensity to specific tube materials, dimensions, and production speed requirements. These specifications align with standard industrial utility configurations.
Q: Is this a complete system or individual heating components?
A: This is a complete, integrated annealing system delivered as a unified package within the 1700×1200×1650mm machine frame. The system includes the high-frequency power supply, induction heating assembly, and operational controls, all pre-configured and tested for tube annealing applications. It arrives production-ready, requiring only connection to utility supplies to begin operation.
Q: What are the physical dimensions and weight of the system?
A: The complete system measures 1700mm in length, 1200mm in width, and 1650mm in height, with a total weight of 300 kilograms. This compact form factor simplifies integration into existing production lines and work cells. Standard industrial flooring is typically adequate without requiring special foundation reinforcement for the 300KG unit weight.
Q: What production applications is this heating system used for?
A: Primary applications include intermediate annealing in tube shrinking production lines and pre-bending heat treatment in tube forming cells. The system serves cable manufacturing facilities processing metal conduit and armor tubes, civilian electrical appliance manufacturers producing heating element tubes, and general metal tube fabrication operations requiring reliable induction annealing capability.
