Product Description
Hot Slag Holding Furnace 2500kW with Silicon Carbide Rod Heating
This holding furnace is built for copper and copper nickel smelters that tap slag at 1250-1350 C and need both a stable hot feed and a quiet zone where entrained matte can settle out. Two independent silicon carbide rod heating zones hold the bath temperature, while a deepened bottom compartment gives the metal droplets 50-70 minutes of residence time to sink and be recovered instead of being lost to the slag.
Key Features
- Silicon carbide rod heating: radiant rods above the bath heat the slag without electrodes or induction coils, so there is no consumable electrode and no water-cooled coil to maintain.
- Integrated settling zone: an 8 m3 bottom compartment slows the slag flow, so copper matte and metal droplets separate by density and are tapped separately.
- Two zone control: charging end and tapping end are controlled independently, keeping the bath within +/- 10 C even when slag arrives in large batches.
- Low holding cost: only heat loss is replaced, and the 130 mm insulation layer behind the chrome corundum lining keeps holding power at 70-100 kWh per hour.
- Simple maintenance: rods are replaced from the top of the roof without entering the furnace, and each zone has an element break alarm in the PLC.
Process Flow
- Converter or smelting furnace slag is tapped through a covered launder into the charging end of the furnace.
- Silicon carbide rods in the two zones maintain the set temperature of the bath.
- Slag flows slowly across the settling compartment, where matte and metal droplets sink to the bottom.
- Recovered metal is tapped from the bottom tap hole on a batch basis; slag leaves through the forward notch.
- Fume is drawn from the roof hood under negative pressure to the plant bag filter.
