Fe-Si-based master alloys with REM are used for ladle treatment of irons and steels.
Their use makes it possible to:
- obtain a vermicular graphite structure of iron
- treat steel
- treat grey iron:
- carry out graphitization
- carry out deep desulphurization of iron
- remove detrimental impurities from melts
Sizes: 1-20 mm
Consumption of master alloys to be introduced into the melt depends on the degree of its contamination with such elements as S (sulfur), P (phosphorus), Sb (stibium), Cr (chromium), V (vanadium).
