4. Core Product Advantages

4.1 Customized Process for Rare & Precious Metal Recovery, Higher Recovery Rate

The furnace hearth structure is optimized for matte capture technology of precious metals, delivering stable and uniform molten pool temperature. The capture rate of Au, Ag, Pt, Pd and other precious metals reaches over 98%. It can treat low-grade slags, waste catalysts, circuit board ash, dedusting ash and other complex mixed materials. Melting, reduction and layered enrichment are completed in one furnace to simplify downstream refining procedures.

4.2 Low-energy Intelligent Power Supply System, Lower Operation Cost

Equipped with special low-loss 3000kVA furnace transformer with multi-stage voltage precisely matching each smelting stage. Optimized low-impedance water-cooled short network cuts power loss. Full-automatic electrode regulation stabilizes electric arc in real time, reducing comprehensive power consumption per ton of raw material by 12%~18% compared with industrial average. The system automatically balances three-phase current with strong harmonic suppression, eliminating the need for extra large-capacity reactive power compensation equipment.

4.3 Full Water-cooled Sealed Structure, Long Service Life & Easy Maintenance

Furnace shell, flue hood, pressure rings and copper tiles adopt forced soft water cooling to resist high-temperature erosion and scouring of precious metal molten slag. The furnace lining is made of special refractory material resistant to matte corrosion for longer maintenance intervals. Modular holders and quick-disconnect water-cooled cables greatly save time on electrode replacement and component overhaul.

4.4 PLC Full Closed-loop Control, Less Labor Dependence

The touch screen centrally monitors furnace temperature, three-phase power, electrode position, cooling water temperature & pressure and feeding flow. Automatic interlock alarm protection activates upon overheating, water shortage or short circuit. Multiple pre-set precious metal smelting process programs support one-click switching for different raw material conditions; operators can get proficient with simple training.

4.5 Environmentally Friendly Sealed Design, Compliant with Hazardous Waste EIA Standards

The semi-sealed flue hood fully encloses the furnace top for centralized flue gas export without scattered dust or odor. Compatible with environmental treatment facilities for hazardous waste recycling enterprises, meeting national environmental acceptance standards for solid waste recycling and rare-precious metal regeneration, facilitating project approval nationwide.

4.6 One-stop Complete Delivery, Full-lifecycle Manufacturer Service

Shaanxi Chengda provides full-chain services including equipment design, manufacturing, integrated delivery, on-site installation, furnace baking & commissioning, and precious metal smelting formula training.
