Medium-frequency induction melting furnaces — for steel, iron, copper, brass, aluminium, lead & precious metals — capacities from 250 kg to 30 ton per heat with IGBT power converters, closed-circuit cooling towers, hydraulic tilting and integrated pollution-control systems.
Scrap, sponge iron, pig iron or alloy charged via overhead crane bucket or mechanical charger into furnace crucible
IGBT power converter ramps up induction power; magnetic field induces eddy currents in metal, melting starts within minutes
Slag formed & skimmed; sample tested for chemistry; alloying additions (Si, Mn, C, Cr, Ni) made to match required steel/iron grade
Final temperature held (1,500–1,650°C for steel) to ensure homogeneous chemistry & thermal mass before tapping
Hydraulic tilt mechanism tips furnace to pour into ladle / billet caster / sand mould — controlled flow, no spillage
Furnace returned to upright; coil & transformer cooling continues; refractory inspected, patched if needed for next heat
Our turnkey package covers the complete induction melting plant — twin furnace shells with IGBT power converter, hydraulic tilting unit, closed-circuit cooling towers, capacitor bank, transformer, control panel and pollution-control system (bag filter / scrubber).
Equipment is pre-assembled, electrically tested at full power and water-tested at our partner facility before container shipment to Africa, where our engineers handle erection, refractory lining, hot commissioning and operator training.
Power-factor correction capacitors, soft-start sequences and IGBT (vs older SCR) deliver smooth starting on weak African HV grids — minimum trip events, maximum heats per day.
Latest IGBT (vs SCR) technology — better power factor, lower harmonic distortion, faster ramp-up, smaller footprint and higher efficiency.
Twin shells share one IGBT power source — one heats while the other taps. Continuous operation, double the throughput per dollar of capex.
Closed-circuit cooling tower (CCT) eliminates open water — protects coil & transformer from scaling & fouling, extends component life by 2-3×.
Bag-filter dust extraction system captures meltshop fumes — meets emission standards in all African jurisdictions and good for worker health.
Furnace refractory linings (silica/alumina/MgO ramming masses), copper coils, water hoses and IGBT power modules stocked locally through Vezora Spare Parts.

* Heat times based on cold-charge melting steel. Hot-heel operation reduces cycle by 15–25%. kWh/ton increases for non-ferrous metals.
Same induction furnace platform handles ferrous & non-ferrous metals — switching between steel, iron, copper or aluminium with appropriate refractory and chemistry control.
Mild steel for re-rolling, alloy steel for forgings & foundry castings — 1,500–1,650°C melting.
Grey cast iron, SG iron, ductile iron for foundry castings (engine blocks, manhole covers).
Copper anode melting, brass alloys, bronze — 1,100–1,200°C with appropriate refractory.
Primary & secondary aluminium melting — 700–800°C, low-power consumption mode.
Gold, silver, lead, zinc, nickel — small-capacity furnaces for mints, refineries, specialty foundries.
From small foundries pouring 500 kg castings to integrated 30-ton steel plants — our induction furnaces serve every African meltshop application.
