copper smelting furnace

Smelting chemically extracts copper from ore or concentrate. Melting or remelting changes solid copper, cathode, returns or qualified scrap into liquid metal for alloying and casting. This product range is mainly for melting and remelting, although “copper smelting furnace” is commonly used as a buyer search term.

IGBT coreless furnaces suit flexible small and medium batches; KGPS coreless furnaces suit large batch loads; channel furnaces suit long continuous melting or holding; gas-fired furnaces suit plants where gas infrastructure and operating cost are favorable.

Pure copper melts at approximately 1,085°C. The working and pouring temperature is higher and depends on alloy composition, transfer time, mold, section size and casting method. It must be defined by the process rather than set from one universal number.

The published IGBT standard table covers 50-250 kg of copper. The current COOLDO project description covers IGBT custom sizes around 10-350 kg and KGPS systems around 300 kg to 10 tons. The usable capacity must be confirmed from metal density and crucible dimensions.

IGBT systems use transistor modules and are commonly selected for responsive small or medium production. KGPS systems use thyristor technology and are commonly applied to high-power, large-batch melting. Grid harmonics, transformer, compensation, cooling and service requirements should be compared for the actual project.

A coreless furnace heats a separate crucible or refractory-lined bath and is flexible for batch operation. A channel furnace circulates metal through an immersed inductor channel and is efficient for continuous holding or melting, but the channel must remain filled and protected.

Yes. Suitable furnace, crucible or refractory, temperature program and fume extraction must be selected for the exact brass, bronze, silicon bronze, aluminum bronze or other copper-alloy grade.

Yes, after the scrap is sorted and prepared. Remove moisture, oil, sealed parts and unknown contaminants. Charge size, surface area, oxidation, slag and fume treatment affect yield, safety and energy consumption.

Consumption depends on furnace type, batch size, charge temperature, operating schedule, lining, power factor and heat losses. The old page cited about 280 kWh/t for one continuous channel-furnace application and about 500 kWh/t for one coreless reference; these are comparison references, not guaranteed values for every installation.

A steel-shell hydraulic furnace has a stronger structure and is generally preferred for heavier heats and demanding industrial operation. Aluminum-shell reducer-tilting designs can reduce initial cost for selected smaller capacities. The decision must include safety, lining method, pouring and maintenance.

It is normally designed for long, continuous operation because the induction channel must remain immersed in molten metal. The original COOLDO guidance recommends roughly 20 hours per day. A coreless batch furnace is usually more practical for short or intermittent schedules.

The original IGBT table gives approximately 20-30 minutes for a hot-crucible heat and 40-50 minutes for the first cold heat. Actual time changes with model, charge, alloy, superheat, crucible condition, voltage and cooling conditions.

Yes. It can be engineered with hydraulic pouring, ingot molds, conveyors, holding equipment or a continuous casting machine for copper rod, bar, wire or strip. The furnace throughput must match the casting machine and product section.
