One Power Supply with Two Furnace Bodies
High-Efficiency Intermediate Frequency Steel Melting Solution
In steel melting and casting production, electrical efficiency, equipment utilization rate, and production continuity directly determine operating costs and output capacity. Traditional single-furnace systems often suffer from idle time during pouring or temperature holding, leading to wasted power capacity and reduced production efficiency.
The Steel Shell Intermediate Frequency Steel Melting Furnace (One Power – Two Furnace Bodies) is designed to solve these issues by using one intermediate frequency power supply to drive two independent furnace bodies, enabling flexible power allocation, uninterrupted smelting, and optimized electrical investment.
System Configuration Overview
This equipment adopts a steel shell furnace structure combined with an intermediate frequency power supply system.
A single IF power supply unit supplies power to two furnace bodies independently, allowing different operating states to be executed at the same time.
Typical Operating Modes
- Furnace A: Steel melting
- Furnace B: Pouring or molten steel holding
- Both furnaces: Preheating and smelting simultaneously
The IF power output can be arbitrarily distributed between the two furnace bodies according to process requirements, ensuring maximum utilization of the power system.
Working Principle and Process Logic
The one power–two furnace bodies intermediate frequency melting furnace uses electromagnetic induction heating to melt steel efficiently.
Power Distribution Logic
- One intermediate frequency power supply
- Two independent furnace bodies
- Power output is adjustable and distributable in real time
This allows:
- One furnace to melt steel continuously
- The second furnace to maintain molten steel at an accurate and stable temperature
- Seamless switching between melting, holding, and pouring processes
As a result, uninterrupted smelting is achieved, eliminating waiting time between batches.
