Low Silicon Ferrosilicon (10-12% Si)
LSF is a complex deoxidizer and has the following advantages in comparison with standard ferroalloys (FeSi 45, SiMn 17):
- Deep deoxidation. The deoxidizing agent acts throughout the volume of the metal in the depth of the bath, which allows to achieve the following effects:
– boiling stops almost immediately, carbon stabilizes;
– Mn burning is reduced, which is important for steels containing Mn;
– due to the mixing of the bath, non-metallic inclusions are better removed.
- Comparison with FeSi 45. From our experience of deoxidation, one part of FeSi 45 and 1.8 parts of LSF can be compared, that is, LSF works as FeSi 20-25.
The material is not stolen, as it is non-standard. It is only necessary to warn the nearby scrap receivers.
- Additional, free iron in the heat. In comparison with 1tn. we get FeSi 45 per 1tn. more iron. (1tn. FeSi 45 = 1.8tn. LSF).
In addition, it must be said that LSF was actively used in the open-hearth production in the 1990-2000s throughout Russia. (Our company sold up to 10 cars per month).
