Smelting Furnace for Sale: Power Up Your Workshop
Are you searching for a smelting furnace for sale that combines cutting-edge safety, energy efficiency, and exceptional build quality? RONGKE, a leading manufacturer of induction melting technology, offers premium intermediate frequency coreless induction furnaces designed to meet the highest industry standards. Whether you’re upgrading your current operation or investing in new equipment, our furnaces provide unmatched performance, long-term reliability, and the ultimate user experience.

Why RONGKE Induction Technology Redefines Efficiency
RONGKE designs begin at the coil – the heart of every induction system. We machine TU1 grade oxygen-free copper tubes in a single cold-extrusion pass, then wind them using our double-coil topology. The result is less electrical resistance and up to 15 % lower power draw under the same melt load. Surrounding the coil, a fully enclosed steel shell acts as a secondary magnetic shield, keeping stray fields to barely 10 % of the national standard and trimming workshop noise by nearly one-third. Engineers who once struggled with buzzing coils now report quieter shifts and fewer rejected parts.
• Built-In Safety: Full-Time Leakage Alarm
Our patented IDE leakage-alarm system monitors every square centimeter of the refractory lining. If molten metal seeps even two centimeters toward the coil, grounding sensors raise a visible and audible alert, while the inverter ramps down automatically. This quick response prevents catastrophic burn-throughs and protects both equipment and personnel.
• Energy-Saving Coil and Magnet Yoke
The furnace yoke uses high-purity directional silicon-steel laminations with magnetic loss below 105 W/kg. Water channels on both sides balance heat extraction, extending the yoke’s working life and keeping bath temperatures stable. Combined with our thick-wall copper conductors, the magnetic circuit concentrates flux exactly where it is needed – a design that translates into faster melts and lower kWh per ton.
Key efficiency gains:
- Up to 15 % power savings per melt cycle
- Noise level 30 % lower than conventional open-frame models
- Magnetic radiation only 10 % of typical industry values
Smelting Furnace for Sale
In today’s climate-aware market, greener production is not optional – it is a competitive edge. RONGKE’s coreless smelting furnace for sale unites speed with sustainability so you can pour cleaner metal and cleaner profits.
First, the closed-loop cooling system circulates distilled water through German carbon-free rubber hoses. These lines resist scale buildup, keeping flow constant and pump energy low. Temperature and pressure sensors feed live data to the furnace PLC, which modulates flow in real time to avoid over-cooling and wasted energy.
Second, a dual-hydraulic tilting drive replaces gearboxes that leak oil and slip after long service. Two synchronized cylinders share the load, delivering smooth tipping torque without the “flutter” that splashes hot metal. Explosion-proof valve blocks and fire-sleeved pipes add another layer of protection, ensuring that an unexpected hose failure never turns into plant downtime.
Environment-ready details:
- Closed dust hood with 360-degree capture cuts airborne FeO by up to 40 %
- CE-certified safety chain meets or exceeds EU workplace directives
The magnet yoke’s high coverage rate – over 70 % – funnels more of the induced field back into the bath, shortening melt time. Less time at high current equals fewer CO₂ emissions per heat. For foundries chasing corporate ESG goals, the numbers matter: customers have verified energy savings of 90 – 120 kWh per ton when replacing older SCR-driven furnaces with a new RONGKE IGBT package.

• Coreless Design for Clean Melts
Because the coil never contacts the charge, there is no crucible contamination. Operators can swap linings to run multiple alloys – cast iron in the morning, high-chrome steel in the afternoon – without cross-pick-up. This flexibility opens new revenue streams and eliminates the need for dedicated units for each alloy family.
• Digitally Controlled Cooling and Tilting
Our Smart-Flow™ algorithm links leakage alarms to the cooling loop. If conductivity spikes in the water circuit, the PLC flags a lining breach long before molten metal reaches copper. Maintenance teams gain an extra buffer to schedule repairs during planned outages rather than emergency shutdowns.
Choosing RONGKE Means Long-Term Value
Buying a smelting furnace for sale is not only a capital purchase – it is a partnership that lasts decades. RONGKE backs every unit with a global service network and data-driven support packages.
A dedicated field engineer visits during commissioning to fine-tune power factors, set leakage thresholds, and train shift leaders. After start-up, our remote diagnostic center monitors key variables – coil impedance, water conductivity, inverter harmonics – and emails weekly health reports. If a reading drifts from baseline, we alert you before an unscheduled stop occurs.
Support, Service, and Global Compliance
• 24/7 remote troubleshooting via secure VPN
• Annual preventive-maintenance kits shipped with OEM-grade spares
• On-site audits aligned with ISO 9001 and ISO 14001
Finally, our spare-parts philosophy is simple: keep it modular, keep it available. Coils, yokes, and PLC boards share common footprints across the entire RONGKE range from 500 kg to 20 t, so you never wait months for a custom casting. Combined with transparent pricing and rapid logistics, you stay melting while competitors stand idle.
