English Charge
Prepared steel, iron or alloy charge is loaded into a correctly lined furnace crucible.
Dinghong manufactures heavy-duty steel shell induction furnaces with rigid welded structures, magnetic yokes and model-specific tilting systems. Configure the furnace body, power supply, cooling and auxiliary equipment around your metal, batch capacity, target output and local electrical conditions.
The DHG steel shell furnace is an intermediate-frequency induction melting furnace designed for repeated foundry production. Its welded steel structure supports the induction coil and magnetic yokes, while the tilting system is selected according to furnace capacity and operating requirements.
As an induction metal melting furnace, the system converts electrical energy into heat inside the metal charge without direct fuel combustion. It is suitable for projects that require controlled batch melting, flexible start and stop, and integration with a matched power supply, cooling circuit, hydraulic equipment and dust extraction system.
A welded steel frame provides mechanical support for demanding operating cycles and large-capacity furnace bodies.
Capacity, power, frequency, cooling and tilting are matched to the metal and production target.
Dinghong can combine the furnace body with power, control, cooling and auxiliary equipment.
A medium-frequency induction melting system transfers energy through the coil and creates induced currents inside the charge, producing rapid internal heating and natural electromagnetic stirring.
Prepared steel, iron or alloy charge is loaded into a correctly lined furnace crucible.
The matched power supply energizes the water-cooled coil and creates an alternating magnetic field.
Induced currents heat the metal while the operator controls power, temperature and production timing.
The configured tilting mechanism transfers molten metal to the ladle or casting process.
Select the nominal furnace capacity together with the required production rate, metal type and matched power supply. A larger crucible alone does not determine tons per hour; melting output also depends on power, charge condition, tapping temperature and operating schedule.

Send the metal, batch size, required tons per hour and local voltage for a model and power recommendation.
A 1 ton, 2 ton, 5 ton or 10 ton induction furnace describes nominal batch capacity—not guaranteed hourly production. The right system begins with the production requirement and then matches furnace capacity, electrical power, cooling and operating arrangement.
A complete induction melting furnace system can be configured with the furnace, matched power supply, transformer, cooling, tilting, control and environmental equipment required for the project. The exact scope is clearly defined in the technical quotation.

The rigid steel shell, long-arc magnetic yokes, model-specific tilting system and cyclonic dust hood are designed to improve furnace durability, energy utilization, operator protection and environmental control in demanding foundry production.
The sturdy welded steel frame supports the coil assembly and resists the thermal and mechanical loads of repeated melting cycles, making it especially suitable for large-capacity furnaces where rigidity and operating safety are priorities. Aluminum shells can experience metal-toughness fatigue and progressive deformation under sustained heat, heavy loads and strong magnetic fields; in intensive foundry conditions, serious wear may appear after about one year. The rigid structure and lower magnetic leakage help the steel shell furnace achieve a substantially longer working life.
Silicon-steel yokes shield the coil-generated magnetic field, reduce external magnetic resistance and limit leakage flux at the coil ends. Their arc-shaped inner faces fit closely against the coil wall, increasing the effective magnetic-conduction area and supporting the coil. Together with the forward-and-reverse winding coil design, this arrangement improves system efficiency and can save approximately 5%–8% energy under matched operating conditions.
The steel shell better resists deformation under high temperature and heavy molten-metal loads. Applicable models use a controlled hydraulic tilting system for safe, reliable pouring. During furnace tipping, the anti-fall protection cover rises automatically to form a protective guard and reduce the risk of personnel falling into the operating area.
The compact cyclonic dust-removal furnace cover collects fumes close to the source while retaining heat, reducing heat loss and improving equipment safety. It occupies less workshop space, tilts forward and backward, and can be held at any required position for charging, treatment and maintenance. For ductile-iron production, it can also capture dust generated during in-furnace spheroidization—an emission point that conventional fixed dust hoods typically cannot cover effectively.

Both furnace types use electromagnetic induction. When comparing the heavy-duty steel structure with an Aluminum Shell Furnace, the appropriate choice depends on capacity, production intensity, tilting requirements, workshop conditions and investment priorities.
| Selection Factor | Steel Shell Furnace | Aluminum Shell Furnace |
|---|---|---|
| Typical priority | Structural rigidity and heavy-duty production | Compact structure and installation flexibility |
| Capacity range | Often selected for medium and large capacities | Often selected for smaller and moderate capacities |
| Tilting arrangement | Hydraulic configurations commonly available | Reducer configurations commonly used |
| Metal and process | Frequently selected for steel and iron foundries | Common in smaller foundries and non-ferrous projects |
| Final decision | Confirm against metal, output, furnace capacity, duty cycle, safety plan and total system cost. | |
