Ferrosilicon

Ferrosilicon is represented by a large group of Fe Si alloys and is mainly suitable for deoxidation and alloying steel. It is widely used in foundry industry to produce iron and steel castings. Powdered ferrosilicon is used as a weighting agent in aqueous suspension for mineral processing, as well as for the manufacture of welding electrodes.

Ferrotitanium lumps should be free of slag, sand and other materials, both on the outer surface and in fracture zones. Only oxide films and traces of foundry facing are allowed.

Ferrotitanium is delivered in crushed lumps not more than 15 kg in mass. The maximum amount of fines passing 10-mm sieve should not exceed 6 % of the batch mass for ferrotitanium grades FTi70C05 (ФТи70С05), FTi70C1 (ФТи70С1) and 10 % for other grades. The amount of fines is not specified for ferrotitanium used to produce welding materials.

Ferrotitanium is transported in special containers, steel drums and wooden boxes. Transportation of bulk ferrotitanium is allowed.
