MACHINE FOR FORMING METAL BARS

摘要

A machine for forming metal bars, in particular for producing ingots made of precious metal such as gold, silver, precious alloys, as well as other pure metals or different alloys, including a melting station for melting the metal contained in an ingot mould, wherein the ingot mould contains an accurate amount of metal, in the form of powder, grits or swarf of various sizes and a chemical additive, which creates a chemical reaction with the impurities contained in the metal. The chemical additive may be any of boric acid, borax, potassium nitrates, ammonium, sodium, lithium and potassium and sodium chlorides.
