Hydraulic titling Small Induction Furnace

The five standard CDO-HT models are listed for 18–100 kg of iron or stainless steel, 50–250 kg of copper, gold or silver, and 18–100 kg of aluminum. Actual capacity depends on metal density, crucible, charge form and process. Larger hydraulic tilting furnaces can be engineered as custom projects.

The catalog lists approximately 20–30 minutes per batch when the crucible is already hot and approximately 40–50 minutes for the first melt from a cold furnace. Actual time varies with the model, metal, charge size, starting temperature and power conditions.

It can be configured for gold, silver, copper, brass, bronze, aluminum, iron, stainless steel and compatible alloys. Crucible or lining selection must match the metal, operating temperature and contamination requirements.

Induction heating provides fast, direct heating without a combustion flame. Electromagnetic stirring helps distribute heat and alloying elements throughout the melt, supporting more uniform alloy preparation and repeatable batch production.

The hydraulic system provides controlled furnace rotation and pouring angle. The operator can control the pour from a separate station, reducing the need to handle a heavy crucible manually and improving alignment with molds, ladles or granulation equipment.

The selected configuration can include PLC and touchscreen monitoring for melting status, power operation and protection functions. Final control components and interface options should be confirmed in the quotation.

Depending on the configuration, protection functions can include over-current, over-voltage, insufficient cooling-water flow and high-temperature alarms. The complete safety design must also include workshop guarding, personal protective equipment, ventilation and operating procedures.

An optional dust-extraction furnace cover can be connected to a correctly designed ventilation and filtration system. The required airflow, ducting and filtration depend on the metal, flux, furnace size and local environmental requirements.

Yes. Continuous circulating-water cooling is mandatory. The standard reference requirements are water pressure of at least 0.3 MPa, flow of at least 20 L/min and inlet-water temperature no higher than 45°C. The final chiller capacity must match the selected furnace and site conditions.

CDOCAST provides a two-year warranty for eligible quality-related faults under the agreed sales terms. Consumables, normal wear and damage caused by incorrect installation or operation are handled according to the quotation and warranty conditions.

Silicon carbide graphite is commonly selected for gold, silver, copper and other non-ferrous metals. Pure graphite may be considered for selected high-purity applications. Steel or iron melting generally requires an appropriate magnesia, alumina or engineered lining to reduce carbon contamination.

Crucibles are consumables measured by melting cycles rather than days. Under suitable operating conditions, a high-quality crucible may provide approximately 40–80 heats, but actual life depends on metal, temperature, flux, charging method, oxidation and thermal cycling.

Dry and preheat a new crucible gradually, avoid impact from heavy charge material, use only the required amount of flux, prevent sudden thermal shock, remove residue correctly and maintain even positioning between the crucible and induction coil.
