Metal recyclers and foundries need more than a furnace that can reach a high temperature. They need stable melting performance, predictable production, safe operation and a system that can connect smoothly with downstream casting equipment.

WOLFU medium frequency induction furnaces are designed for these requirements. By combining induction heating technology with configurable furnace bodies, tilting systems, cooling equipment and casting units, WOLFU provides practical melting solutions for copper, aluminum, steel, iron and alloy materials.

For customers operating a recycling plant or foundry, the result is a more complete path from scrap metal to usable ingots.

What Is a Medium Frequency Induction Furnace?

A medium frequency induction furnace uses an alternating electromagnetic field to heat and melt metal inside a crucible. The process transfers heat directly to the metal, which supports fast heating, stable temperature control and efficient use of electrical energy.

Compared with traditional fuel-fired furnaces, induction melting does not rely on an open flame inside the melting chamber. This supports a cleaner working environment and makes the furnace easier to integrate into an automated production line.

Depending on the model, WOLFU systems can include automatic frequency tracking, electromagnetic stirring, water cooling, PLC control and multiple electrical protection functions.

WOLFU Medium Frequency Furnace: From Scrap to Ingot

WOLFU’s medium frequency furnace and ingot casting production line is designed as an integrated metal processing system. The typical workflow includes:

1. Charging: Scrap copper, aluminum, steel, iron or alloy materials are loaded into the furnace.
2. Induction melting: Medium frequency power rapidly heats the material until it reaches the required molten state.
3. Temperature control: Stable power output and monitoring help maintain suitable process conditions.
4. Tilting and pouring: A hydraulic or customized tilting system transfers molten metal to the next stage.
5. Ingot casting: Molten metal is poured into molds to produce copper ingots, aluminum ingots or other cast products.
6. Cooling and demolding: A conveyor, spray cooling system and demolding section can be integrated for continuous production.

This configuration allows the melting furnace to work as part of a complete production line instead of operating as an isolated piece of equipment.

Main Applications

Copper Scrap Melting

Copper scrap can be remelted and converted into ingots for further processing, casting or manufacturing. A suitable induction melting system helps operators manage heating, temperature and pouring more consistently.

Aluminum Scrap Recycling

Aluminum recycling plants require efficient melting and reliable transfer of molten metal. WOLFU aluminum melting furnace systems can be configured for aluminum scrap, aluminum alloys and ingot production.

Steel and Iron Melting

Medium frequency induction furnaces are also used in foundries, steel recycling operations and alloy processing plants. Depending on the furnace size and power configuration, the system can support batch melting and continuous industrial operation.

Foundry and Secondary Metal Processing

The furnace can be integrated with casting equipment, billet-making machines, reheating furnaces and rolling mills. This makes it suitable for customers who want to expand from simple scrap melting to a more complete metal processing plant.

Key Advantages of the WOLFU System

Fast and Efficient Melting

Medium frequency induction heating delivers heat directly through electromagnetic induction. This supports rapid heating and can reduce the time required for each melting cycle compared with conventional methods.

Stable Temperature and Power Control

Consistent power output helps operators maintain a stable melting process. This is important when the final product requires repeatable composition, temperature and casting quality.

Flexible Configuration

WOLFU offers different furnace capacities and electrical configurations for small, medium and industrial production requirements. Furnace coils, tilting systems, control cabinets and casting equipment can be selected according to the material and target output.

For the copper and aluminum ingot casting line presented by WOLFU, the published product information lists a production capacity of up to 2 tons per hour and a 660 V configuration. Actual capacity, voltage, power and furnace size should be confirmed according to the customer’s material, production plan and local electrical conditions.

Safety Protection

Depending on the selected configuration, the system can include protection against over-current, over-voltage, overheating, phase loss and insufficient cooling water. Water temperature and pressure monitoring can also help protect critical components during operation.

Easy Integration and Maintenance

The modular design of the electrical cabinet and auxiliary systems helps simplify installation and maintenance. WOLFU can also support factory layout planning, equipment connection and production line integration.

Designed for Continuous Industrial Use

WOLFU medium frequency induction furnace systems are designed for stable, long-term operation. With proper refractory maintenance, cooling-water management and regular inspection, the equipment can support demanding recycling and foundry environments.

What the WOLFU Field Installation Shows

The site photographs show a large industrial workshop with multiple furnace stations installed in a production area. The site includes substantial equipment foundations, furnace pits, overhead lifting equipment and space for material handling and maintenance.

These details are important because a successful induction melting project depends on more than the furnace itself. The layout must also consider charging, molten-metal transfer, cooling, casting, lifting, worker access and future maintenance.

WOLFU’s engineering support covers the complete project, from equipment selection and plant layout to installation guidance, commissioning and operator training.

How to Select the Right Furnace

Before choosing a medium frequency induction furnace, buyers should prepare the following information:

• Metal type: copper, aluminum, steel, iron or alloy
• Raw material form and density
• Required batch size or hourly production
• Target melting temperature
• Required casting product and ingot dimensions
• Available voltage and power supply
• Preferred manual, hydraulic or automatic tilting method
• Factory space and cooling-water conditions
• Whether the project requires a complete ingot casting line

With these details, WOLFU can recommend a suitable furnace capacity, power system, coil design, cooling arrangement and casting configuration.
