Ferro Silicon Powder in Powder Metallurgy
A powder with about 15% Si=content is used because in it the magnetic properties are well distinguished and the specific gravity is high. With a Si=content of 18-20% the spec, gr. is lower and the limit of magnetizability is near. With a content of only 12-14% Si resistance to corrosion is lessened. The 15 % ferrosilicon is melted in a special electrical furnace. The desired Si=content is obtained by melting down a suitable mixture of scrap, gravel and carbon. It is, of course, possible to start with the available low percentage ferrosilicon and to add gravel and carbon, or to blend high percentage ferrosilicon, such as is obtained from the carbide furnace operation, with scrap only. If a considerable amount of slag occurs during the process, the standard electrode- furnace is more suitable than an induction furnace, because the lining of the latter is easily corroded by slag. The melt in the furnace reaches a temperature of approx. 1300掳 C (2350掳 F).

Ferrosilicon Powder Manufacturing Process
By Grinding
In the standard process liquid ferrosilicon is removed from the furnace, cooled, crushed, and ground to the desired fineness. Fine and coarse powders are available. The finer one is preferred in the first stages of a sink and float plant. After some running time the coarser quality is added to make up the loss and to correct wear. The actual separating vessel is of great importance; it should be so formed that the heavy sink product at its bottom cannot grind the ferrosilicon as in a ball mill.
In many cases wet grinding is preferred as the less expensive process. This, however, is done locally because the ground sludges cannot be transported easily. Any drying must be carried out with extreme care because at higher temperatures decomposition occurs in consequence of increased corrosion. These grinding plants are rather expensive, and are often not running to their full capacity; yet it is useless to build a smaller plant for the mills must have a certain size for an economical treatment of this material. Ferrosilicon with a higher Si-content (for example, 45 or 75% Si) can be ground more easily because it is more brittle than the 15% which, as has been shown in tests, possesses a certain toughness making comminution difficult. Tests have shown that the grinding operation causes great wear of the mills and is costly.
