Aluminium Melting Furnace
Aluminium Melting Furnace
ACME FURNACE offers Aluminium Melting Furnaces that provide reliable and efficient solutions for melting non-ferrous metals such as aluminium, lead, and zinc. The selection of heating technology is based on specific requirements related to melt quality, production rate, and overall energy efficiency.
Both electrically heated and gas-fired furnace options are available, allowing flexibility in operation. From a cost perspective, the choice of heating method is largely influenced by local energy availability and pricing, ensuring an optimal and economical melting solution for the end user.
Gas-Fired Heating
Gas-fired furnaces are well suited for metal melting applications, especially when designed with exhaust gas discharge over the crucible edge. For applications where superior melt quality is critical, side exhaust gas discharge is preferred. However, achieving higher melt quality through this method results in reduced energy efficiency, as side exhaust gas discharge furnaces typically consume approximately 20–25% more energy compared to furnaces with exhaust gas discharge over the crucible edge.
Modern fuel-fired furnaces equipped with recuperative burner systems offer an optimal balance between high melt quality and energy efficiency. In these systems, hot exhaust gases are passed through a heat exchanger to preheat the combustion air before it enters the burner. This heat recovery process can deliver energy savings of up to 25% when compared to conventional gas-fired furnaces with side exhaust gas discharge.
Electric Heating
Where melt cleanliness and energy efficiency are of primary importance, electrically heated furnaces are the preferred solution. Electric heating allows highly stable and precise temperature control, while completely eliminating contamination caused by combustion gases. These furnaces can achieve up to 85% of the melting performance of gas-fired furnaces with side exhaust gas discharge.
For applications limited to metal holding rather than melting, electrically heated holding furnaces are recommended due to their excellent insulation and reduced connected load, resulting in significantly lower energy consumption.
