It is often necessary to modify the composition of iron or steel melts by adding elements such as carbon or silicon, to remove undesirable constituents such as sulphur or oxygen, or to ensure that the casting solidifies with a specific metallographic structure. To meet these needs we supply a number of products, each formulated to give maximum performance efficiency. Many of these products can be supplied in pre-weighed units for easy application.

Non-Ferrous Metal Treatment, Inoculants and Fluxes

Metallurgical properties have to be controlled during the production of aluminium castings and other non-ferrous alloys, for example:

• Removing hydrogen (a cause of porosity) using a degassing treatment
• Modifying the metal by the controlled addition of alloying mixtures
• Optimising the crystal structure of the cast metal by grain refining
• Protecting the molten metal from oxidation and removing slag using powder fluxes
  

Foseco is at the leading edge of industry efforts to improve the metallurgical performance of castings. We provide a wide range of metal additives such as powder and granulated fluxes (case study 6), grain refiners and alloying additions as well as application equipment such as mobile degassing units.
