BERNA FORNI INDUSTRIALI

Melting furnace for secondary aluminium

The melting furnaces with a molten aluminium  capacity from 5 to 140 Ton. (fixed or tilting) are studied in order to achieve high production and a metal flow equal to 12-15% of the bath capacity.
The heating is with standard or regenerative burners and combustion plants studied in order to achieve the maximum energy saving using different fuels (fuel oil, diesel oil, natural gas, LPG).

Double chamber furnaces, suitable for melting scrap with organic contents without salt use, are equipped with metal circulation pumps or stirrer in order to increase the efficiency.

The fixed or tilting molten aluminium holding furnaces are produced with a capacity from 5 to 140 Ton.

The heating is with combustion plants suitable for using different fuels (fuel oil, diesel oil, natural gas, LPG).

The refractory lining is studied in order to avoid heat losses through the walls.

Furnaces for aluminium alloys parts producers

The melting and holding furnaces (fixed or tilting) are of two main types:

Central furnaces suitable for melting ingots and in-house scrap, with capacities from 1 to 50 Ton. These furnaces are designed with melting capacity suitable to the needs of machines which will use the alloy molten in the central furnace. Their configuration varies from furnaces with a molten metal high flow, approximately 35-40% of the bath capacity, to furnaces with molten metal high flow of approximately 10 times the bath capacity.
The heating is with combustion plants suitable for using different fuels (fuel oil, diesel oil, natural gas, LPG).

Melting and holding furnaces  connected to casting machines with a capacity suitable with the machine’s production.
The heating is with combustion plants suitable for using different fuels (fuel oil, diesel oil, natural gas, LPG) or electric resistances.
