Twin-Chamber Melting Furnace TCF®

Recycling of Aluminium is an important factor for the environmental footprint for the use of Aluminium. The Twin-Chamber Melting Fur¬naces TCF® provides a process for recycling of used and production return scrap without previous scrap treatment. The process reduces metal loss and offers high energy efficiency and environmental friendly operation.

The Twin-Chamber Melting Fur­nace TCF® consists of two chambers in a common furnace casing. The chambers are separated in order to allow separate and independent processing for scrap melting and furnace heating.

Scrap is loaded to the charging machine and put onto the dry hearth of the scrap chamber. Here the processing starts with preheating, drying and pyrolysing. The gas evaporating from the scrap's contaminants are transferred to the heating chamber for complete burning. While the scrap chamber is working in inert condition, the heating chamber provides optimum conditions for complete burning of fuel and pyrolysis gas.

Ingots, T-bars or thick-walled clean scrap can be put into the heating chamber, which is also equipped with a dry hearth for drying the incoming goods.

Homogeneous temperature and alloy composition is provided by a liquid metal pump. The pump sucks in liquid metal from the heating chamber bath and pushes it into the scrap chamber bath area. By way of the Charge-Well melting of alloying components and chips is possible.

The salt-free furnace operation contributes to the environment friendly recycling of Aluminium scrap.

The central regenerator CCR quenches the flue gas in order to avoid recombination of harmful components and recovers the heat from flue gas by heating up the combustion air in front of the burners.

Wide door openings and flat walls allow easy charging, cleaning and inspection.
