72% 75% Ferro Silicon on Sale Produced by Top Manufacturers
High-silicon Ferro Silicon Alloy is used as a reducing agent for the production of low-carbon ferroalloys in the ferroalloy industry. Silicon powder with a silicon content of about 15% (particle size <0.2) is used as a weighting agent in heavy media separation.
Ferro Silicon Briquette production process:
The production equipment for Ferro Silicon Granules is a submerged arc reduction furnace. The silicon content of Iron Silicon Alloy is controlled by the amount of iron raw material added. To produce high-purity ferro silicon, in addition to using pure silica and reducing agents, external refining is also required to reduce impurities such as aluminum, calcium, and carbon in the alloy.
Iron Silicon with Si ≤ 65% can be smelted in a closed electric furnace. Ferro silicon with Si ≥ 70% must be smelted in an open or semi-closed electric furnace.
