Ferro Silicon is produced in Sub-merged Electric Arc Furnaces by the Carbothermic smelting of the Quartz. Even though the process is a slag less there is some inev itable generation of slag in the process. The extent of slag formation depends on the control exercised on the furnace parameters and the raw material quality.The technology of self-reducing pellets for ferro-alloys production is becoming an emerging process due to the lower electric energy consumption and the improvement of metal recovery in comparison with the traditional process. This paper presents the effects of reduction temperature, addition of ferro-silicon

In the conventional production of stainless steels, chromium is generally introduced to the process in the form of Cr-Fe-C-Si alloys, principally as high-carbon ferrochrome or charge chrome. The level of carbon and silicon in the above alloys is important especially when refining is carried out by blowing oxygen in the melt.Iron-silicon phase diagram The phase diagram of the Fe-Si binary system is at Fig 1. Iron-silicon phase diagram shows the phases which are to be expected at equilibrium for different combinations of Si content and temperature. Fig 1 Phase diagram of the Fe-Si binary system Application The following are the common application areas of Fe-Si.
