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.

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.
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.
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.
