At the Parona factory, the scrap pre-treatment phase requires the use of sophisticated systems for size reduction (crushing and pressing), selection, sorting, decoating and drying, in order to obtain improved and environmentally compatible raw materials through the removal of impurities, plastic, oils and other organic substances. In order to give the system flexibility, an extensive range of kilns is used in the melting process: rotary kilns, fixed and tilting, tank furnaces and holding furnaces for the addition of master alloys and alloying elements. The casting and automatic making-up operations also enable ingots (traditional and continuous casting) and stacks to be produced in very diverse formats, to satisfy all types of customer requests. There is also a dedicated line for the production of small hemispherical pieces destined for steelworks.

 

Production trimmings are then treated to recover the residual aluminium, recycle the salt and to produce ArgAlumĀ®, a patented material destined for the construction industry. Finally various cutting-edge systems are dedicated to the treatment of atmospheric emissions and water (both process and cooling water and first and second flush rainwater) and to ammonia abatement, with the production of ammonium sulphate for use in the fertilisers sector.
 

The Ambivere site is dedicated to the production of billets for extrusion or stamping in all commercial alloys and plates for laminating and for direct use to create moulds or finished pieces up to 2,500 mm in width and 12 tonnes in weight. The raw materials used are rough metal, processing waste and scrap sent by customers for transformation. Indirect melting furnaces (without contact with the flame) are used to contain oxidation, avoid contaminations of the metal bath and control the yields. The waste gases are suctioned off and treated with the use of appropriate additives in three installations that can be connected to guarantee the process continuity.

 

The potential for customizing production to meet any customer request is enormous, thanks to the homogenization and technical treatment systems and to the three cutting lines. Special attention is paid to quality control, with procedures continually updated in order to obtain more and more detailed applications and increase product reliability. There is continuous monitoring of operations, with maximum attention given to evolving technologies and constant studies and experimentation.
