Abstract:
Aluminium shots and knotch bars
are used as deoxidiser in steel plants.
The deoxidisers are of two types: (i)
Aluminium (ii) Ferrosilicon. Aluminium
has certain advantages over the
Ferrosilicon, as it is cheaper and can
be easily made in the form of shots or
ingot. Aluminium shots have the
comparative advantage i.e. they offer
greater surface area in better contact
and mixing.
