Powering
The Future With
Induction Technology

Furnace batch capacity (kg) must be calculated based on three practical foundry parameters rather than nominal nameplate targets:

• Single-Pour Mold Demand: The volume of molten metal needed for your single largest casting or simultaneous ladle cluster.
• Shift Production Requirement: Target Shift Output (kg) = Batch Capacity (kg) × Achievable Heats per 8-Hour Shift.
• Pouring Duration Window: Mold filling should conclude within 8–12 minutes of tapping to prevent temperature decay and cold-shuts in thin-walled molds.

Electrical power (kW) is determined by the specific heat (Cp), latent heat of fusion (Lf), tapping temperature (Ttap), and desired melt cycle time:

New Tech calculates power to balance transformer capacity costs while ensuring you achieve full rated melt throughput without grid penalty charges.

Operating frequency determines the electromagnetic penetration depth (δ = 503 √(ρ / μr·f)) and the natural electromagnetic bath stirring force:

• Medium Frequency (500 Hz – 1.5 kHz): Deep penetration for heavy ferrous foundries (500 kg to 3,000 kg). Provides vigorous stirring essential for rapidly dissolving heavy steel scrap, carbon recarburizers, and ferrosilicon inoculants.
• Medium-High Frequency (2 kHz – 4 kHz): Optimal inductive coupling for non-ferrous metals (50 kg to 500 kg copper, brass, aluminium). Moderate meniscus stirring maintains alloy homogeneity while preventing zinc volatilization in brass.
• High Frequency (8 kHz – 30 kHz): Shallow penetration ideal for small crucible sizes (1 kg to 25 kg gold, silver, dental alloys) and surface induction hardening/brazing operations.

New Tech solid-state parallel resonant inverters feature automatic frequency tracking to maintain resonance as the charge passes through the magnetic Curie temperature (770°C).

Induction furnaces require a dedicated dual-loop closed water cooling circuit to protect power semiconductors and the energized coil:

New Tech provides complete skid-mounted pumping stations with standby dual pumps, digital rotameters, and sub-15ms flow-interlock trip circuits.

Site commissioning timelines depend on machinery scale and site readiness:

• • Compact / Tabletop Systems (5 kW – 25 kW): 1 to 2 business days. Pre-assembled on skids; requires only incoming 3-phase power and chiller hose connection.
• • Foundry Tilting Systems (40 kW – 160 kW): 3 to 5 business days, including civil anchor leveling, water manifold interconnections, and initial crucible sintering heat.
• • Heavy Foundry Bays (250 kW – 500 kW+): 7 to 10 days covering hydraulic power pack testing, substation cabling, transformer tie-in, full-load melt certification, and operator training.

Civil foundation requirements vary strictly according to furnace mechanical design:

New Tech issues certified foundation drawings with civil load calculations, hydraulic trench depths, and vibration isolation specs upon purchase order sign-off.

To ensure continuous stable operation without utility grid disturbance, prepare the following on your electrical panel:

• Supply Voltage: 415V ± 10%, 3-Phase, 50 Hz (or 380V/480V at 60 Hz for international shipments).
• Transformer Sizing (kVA): Minimum kVA rating = 1.15 to 1.25 × Machine kW (e.g. 100 kW inverter needs ~125 kVA dedicated capacity).
• Dedicated Chemical Earth Pits: Two isolated earth pits with earth resistance < 1.0 Ω: (1) System structural chassis earth, and (2) Furnace hearth leakage safety ground.
• Harmonic Filtering: New Tech inverters include built-in tuned line reactors to suppress THDi < 4.8% per IEEE 519-2022 standards.
