In Vienna, the Austrian factory has Ögussa GmbH, which produces billets for jewelry factories and workshops.
It is also engaged in manufacturing of laboratory equipment, non-ferrous and precious metals, pours dimensional gold and silver bullion.
The raw materials used for the bullion jewelry scrap, defective and fashion jewelry.



 
Applicants for melting scrap gold is loaded into special furnaces under the influence of a high temperature liquid is brought to a homogeneous mass, which molds to produce ingots.

Material entering the melt, called the feedstock, or blend. The charge may be a pure metal, ingots and defective products, scrap and waste of jewelry production. Feedstock material required to be subjected to various processing.



Waste and scrap of precious metals are a cleansing process, and only then enter the melt.



The melting of precious metals produced in induction furnaces with a graphite crucible. The charge material is charged into the crucible - melting furnace refractory vessel in which molten metal.



The crucible before loading it into a heated metal on the bottom of the heated crucible is filled flux. Then, the crucible is charged with the charge and set the desired temperature. After melting of the charge melt covered with a small amount of fresh flux and mixed. Without lowering the heating temperature, the melt is allowed to settle to the flux otshlakoval unwanted oxides and impurities introduced deoxidizer.
