Ferrosilicomanganese


Ferrosilicomanganese – is a brittle alloy of iron, silicon and manganese, which is used in metallurgy as a steel desoxidant and for the alloying thereof. It gives the iron alloys durability, wearing capacity and impact value. Ferrosilicomanganese as goods grades differ from each other according to the phosphor content and granulometry thereof.

Granulometry:

Fractions: 0–5 mm, 10–50 mm, 10–80 mm, 10–100 mm, 0–300 mm.

Ferrosilicomanganese granulometry structure must correspond to the grain size category from the table below:

By the delivery of Ferrosilicomanganese of a 6-grain size category, small particles content of 0 to 5 mm should not exceed 10%.
