SINC Thermal - Model Infinity Shaft -Melter Furnace for Efficient Metal Processing
FromSINC Thermal LLC
The Infinity Shaft Melter Furnace is engineered to optimize metal melting operations by utilizing a unique 'choked' shaft design that efficiently manages charge material feed into the melting zone. This system captures and redirects hot exhaust gases through the shaft to preheat the incoming charge, considerably enhancing energy efficiency. The carefully crafted hearth design allows the molten alloy to gradually transfer into the holding chamber before entering final superheating stages. This process minimizes hydrogen absorption and reduces dross carryover, leading to improved output quality. The furnace is available in both static and tilting configurations, catering to different operational requirements. These features collectively make the Infinity Shaft Melter Furnace an advantageous option for industries focused on maximizing efficiency and precise control over metal melting processes.Most popular related searches

Aluminum shaft or stack melting furnaces are now widely accepted as a sound financial and operational choice offering controllable and reduced cost of ownership along with improved metal quality. Infinity Furnace characteristics:
- ‘Melt on demand’ operation
- Energy efficiency
- Low metal loss
- Optimum holding capacity
- Reduced molten inventory
- Energy recuperation
- Charge pre-heating
- Easier cleaning
- Low maintenance
Infinity Shaft Melter Furnace utilizes a “choked” shaft to hold charge material and dispense it into the melting zone as it becomes depleted. The hot exhaust gases flow through the shaft to preheat the incoming charge, improving energy efficiency. The hearth design allows the molten alloy to flow gently into the holding chamber before superheating, reducing hydrogen pick-up and dross carryover.
Typical Performance Parameters
- Melting rates: 2,200 to 11,000 lbs/hr (~1,000 – 5,000 kg/h).
- Holding capacity 2 – 4 times melting rate.
- Holding temperatures 1,275-1475°F (690 – 800°C).
- Energy consumption – typical 813 – 1007 Btuh/lb (525 – 650 kWh/ton).
- Metal loss – less than 1.5% (typically less than 1%).
NOTES
- Performance numbers are for furnaces with full charge shaft and density charge materials and at 1,325°F (720°C) holding temperatures.
- Charge materials – optimum is 50% ingot + 50% foundry returns.
- Foundry returns and other materials should have a bulk density of a minimum 28 to max 47 lbs/ft³ ~(450 to max 750 kg/m³).
