4. Aluminium Alloys and Modifications
Once the attested Al alloy has been received from the smelting works, an input control of the chemical
composition is performed using a Spectrocast device.
The achieved values are compared with the certificate from the smelting works and the EN 1706
standard. The values are stored. The inspected alloy is released for production. The Al alloy types are
Device for measuring the Dichte Index marked with internal colours in order to avoid any confusion.
The Al alloy is melted in a gas smelt furnace (Morgan, Striko Vestofen). The smelted alloy is
transferred to an electric resistance furnace, where it is refined using cleaning salts. The alloy is then
modified (Na modification, Ti inoculation and Mg alloying).
An FDU (Foundry Degassing Unit) degassing device by Foseco is used in order to guarantee the
alloy’s low hydrogen content. The chemical composition is then checked again using the Spectrocast
device.
An Ideco thermo analyser is used to ascertain the progress of the solidification, the correct alloy
modification and the primary grain size.
The hydrogen content in the smelt is set using a MK Industrievertretungen GmbH MK 2200–LC
device. The established alloy gasification values /the Dichte index/ are stored and presented to the
client upon request.
