At Luoyang Judian, we specialize in high-performance induction melting solutions for industrial applications. In this guide, we’ll walk you through the key auxiliary systems that support the efficient operation of a medium frequency induction furnace—crucial for foundries and metal processing plants aiming to optimize production.
Why Auxiliary Equipment Matters
A medium frequency furnace is more than just its melting chamber. To achieve stable, safe, and efficient operation, it must be paired with a complete set of support systems. These auxiliary units enhance performance, extend equipment lifespan, and ensure energy-efficient metal melting.
1. Furnace Body: The Core Melting Unit
The furnace body is the heart of the system and typically includes:
- Furnace cover
- Inductor (coil)
- Crucible
- Furnace frame
For small and medium operations, it’s common to install two furnace bodies—one in active use and the other on standby. This setup minimizes downtime and ensures production continuity during maintenance or emergencies.
2. Power Supply & Electrical Control System
The medium frequency power supply and control cabinet function as the furnace’s brain. This system regulates all operations and includes:
- High/low voltage switchgear
- Medium frequency generator or SCR converter
- Power conversion switches
- Compensation capacitors
- Front-panel control console
These components work together to manage current transformation, energy distribution, and system responsiveness—ensuring precise, consistent melting performance.
3. Transmission System: Movement & Tilting
The transmission device controls mechanical operations such as:
- Opening and closing the furnace lid
- Tilting the furnace for pouring
- Resetting furnace position
These movements are usually powered by electric or hydraulic drives and play a critical role in safe, efficient material handling during the melting process.
4. Water Cooling System: Heat Management
Induction furnaces generate intense heat, making a reliable water cooling system essential. This includes:
- Water pump
- Cooling tower
- Water tank
Proper circulation helps maintain coil temperature, protects critical components, and prevents system failure due to overheating.
Best Practices for Efficient Furnace Operation
To get the best results from your medium frequency furnace system, pay attention to these operational guidelines:
- Pre-dry all raw material before charging. Never add cold, wet scrap directly into molten metal.
- Avoid metal chips during the first furnace cycle to protect the furnace lining from penetration.
- Preheat the furnace to ~1000°C before introducing molten iron or switching to full induction.
- Ensure the charge material is dense, clean, and free of rust, oil, or slag to maintain heating efficiency and reduce impurities.
- Use maximum power input from the start to speed up melting and shorten cycle time.
Energy Efficiency & Process Optimization
To reduce energy consumption and improve yield:
- Implement strict process control across melting, casting, heat treatment, and cleaning.
- Regularly monitor power supply voltage drops and cooling system performance.
- Choose equipment with reliable after-sales support and technical guidance.
