Melting Technology

UBC and Aluminium Scrap Decoaters:

Complete UBC pyrolytic decoater units with direct heating of the UBC scrap through recirculated gas. The equipment can process selected size scrap from the Customer storage to the feed of the melting furnace. The scrap is heated in a rotary drum where the gas temperature and oxygen content are controlled. The exhaust gas is processed in a thermal oxidizer followed by a quencher to allow control of the emissions. The organic content in the processed scrap is lower than 0.1 % wt allowing the best results in metal recovery and operation of the melting furnace.


Single Chamber Melting Furnaces:

Melting furnaces for aluminium alloys. Stationary design with melt transfer pump or tilting design. Front door to maximize the charge amount. High efficiency regenerative burners for low specific fuel consumption and NOx emissions. High quality refractories and engineered insulation to provide extended service life. Motorized chimney valve to perform internal pressure control.


Double Chamber Melting Furnaces:

Double chamber melting furnaces for aluminium alloys. Stationary design with melt transfer pump. Front door to maximize the charge amount of coated scrap in the cold chamber. Front door or side door hot chamber for clean scrap. Adjustable oxy-fuel burner in the cold chamber to maximize the HC combustion and reduce emissions. High efficiency regenerative burners in the hot chamber for low specific fuel consumption and NOx emissions. Design with molten metal stirrer or recirculation pump available. High quality refractories and engineered insulation to provide extended service life. Motorized chimney valve to perform internal pressure control.


Holding Furnaces:

Holding furnaces for aluminium alloys. Stationary design with melt transfer pump or tilting design. Front door for cleaning/inspection. Regenerative or direct burners available. High quality refractories and engineered insulation to provide extended service life. Motorized chimney valve to perform internal pressure control.


LEC Stirrer (Low Energy Consumption):

Without stirring the submerged scrap would take a very long time to melt down as it relies on conduction and convection heat transfer. Stirring the bath breaks this limitation and the heat transfer is greatly increased by convection effects.
The Low Energy Consumption stirrer in both versions for Melting & Holding furnaces creates a strong turbulent flow mixing the melt in the vertical & horizontal directions.
This flow has a lot of benefits like increase melting capacity, speed up alloying process and reduce dross generation.




Charging Machine:

  • Longitudinal displacement from the scrap loading area to the front side of the furnace;
  • Easy box design to allow fast introduction;
  • Weighing system;
  • Incorporated hood for an easy coupling with furnace door hood;
  • Laser scanner protection.




Skimming Machine:

  • Longitudinal displacement from the parking position up to furnaces;
  • Movement of the arm in/out of the furnace;
  • Movement up/down of the arm with force control;
  • Movement for discharging the dross;
  • Laser scanner protection.




Dross Cooler:

Melting Technology has studied a new way to recover aluminum from furnaces dross: the PE Dross Cooler. Due to thermiting, the cooling time may take many hours to cool below 400°C, the temperature at which thermiting ceases depending on the cooling process. Various cooling methods are in existence: vibrating table, rotary drum cooler, dross press and last, but not least, the PE Dross Cooler. This method is the most efficient, safest and environmentally sound of all the cooling methods. The recovery of aluminum with PE Dross Cooler is always higher than with other methods: this can be explained by the fact that thermiting is stopped as soon as the inert gas is applied.
This new equipment can process up to 1200 kg of dross (black and non-reactive or white and reactive) and should be placed nearby the furnaces to minimize the oxidation time before cooling.




Annealing Furnaces:

Batch annealing furnaces for aluminium strip coils. Indirect heating through recirculating internal atmosphere and stainless steel radiant tubes. The tubes are heated by gas burners with heat exchanger for fuel saving. The internal atmosphere can be air or inert gas, managed in fully automatic cycle. Engineered insulation and burner operation allow high fuel efficiency.
