Atomised ferrosilicon 15% is manufactured by melting fesi 75% ferrosilicon with premium scrap steel in an induction furnace. The melt is then blown into small particles by high pressure water jetting system. It is then dried and sieved into different grades and packaged as per customer’s request.
Atomised fesi has the following properties:
(a) resistance to abrasion,
(b) resistance to corrosion,
(c) high specific gravity,
(d) magnetism, which allows easy magnetic recovery with subsequent easy demagnetization
