Furnace Design Details

In order to ensure the strength of the furnace body, the steel shell furnace above 25 tons is designed to be semi-open design.

Furnace Design
Advanced Rodless Induction Coil

By using horizontal winding process, the effective coil and the water-cooled coil can be wound from the same oxygen-free copper tube without any segmentation. Coil turn gaps are tight and consistent for maximum electrical efficiency.

Frequently Asked Questions
Q1: What are the advantages of the semi-open steel shell furnace design?
The semi-open design is specifically engineered for large capacity furnaces (above 25 tons) to ensure maximum structural strength and safety during heavy industrial melting operations.
Q2: How does the rodless induction coil improve efficiency?
Rodless coils are wound from a single oxygen-free copper tube without segmentation. This horizontal winding process ensures tight gaps and consistent performance, leading to higher electrical efficiency compared to common coils.
Q3: Does the power supply system help in reducing energy costs?
Yes. The system maintains a very high power factor (0.95-1) throughout the melting process, which significantly reduces reactive power loss and overall energy consumption.
Q4: What happens if a core component fails during production?
The system features an "emergency backup" concept where core devices like thyristors and capacitors have spare modules. These can be activated instantly to keep production running while the damaged part is repaired.
Q5: Can I increase the furnace capacity in the future?
Yes. Due to the modular assembly design of the power cabinet, you can upgrade your production capacity by simply adding relevant modules to your existing setup rather than purchasing a completely new system.
Q6: Is technical training provided for the operators?
Comprehensive training services are provided to instruct employees on system operation, maintenance, and safety protocols to ensure smooth and efficient furnace management.
