Ferro Alloys are the mandatory additives that give Steel the desired qualities and thus an important and inalienable part of Steel making. They are mainly categorized as Bulk Ferro Alloys and Noble Ferro Alloys**. The furnaces use self-baked Soderberg electrodes. RgCON furnaces are designed to capably produce all bulk ferro alloys and similar power intensive commercial products namely:

• HC FeMn
• HC SiMn
• FeSi
• HC FeCr
• MC SiMn
• FeSiCr
• CaC₂
• Pig Iron

FeSi and Si-Metal have the option of collecting fume silica which is a marketable product when densified* to 600kg/m³.

(*) RgCON can offer micro-silica densification units in collaboration with partner company.

(**) RgCON can offer technology for Noble Alloys namely as below, in collaboration with partner companies:

• FeNi
• FeV
• FeB
• FeMo
• FeTi

Silicon Metal is an alloy that has wide and far-reaching application. Extremely power intensive and important component in the composition of many premium products including, industrial, aeronautical, aesthetic, prosthetic, electronics, space flight etc. The furnaces use electrodes of pre-baked Carbon. RgCON has ventured recently into Silicon Metal furnaces and the furnaces can produce Silicon Metal of various grades namely:

• Si 553MG
• Si 2202MG
• Si 3303MG
• Si 1101MG

Normally the furnaces produce 553MG Silicon Metal. The refined grades such as 2202MG, 3303MG, 1101MG are produced through refining process*. The fumes are saleable when densified* to 600kg/m3.

RgCON has ventured recently into Titanium Slag furnaces*. Ti-Slag is an important component in the composition of many high strength products including, industrial, aeronautical, electronics, space flight, paints & pigments etc. The slag can be produced in both AC & DC Arc Furnaces. The furnaces use prebaked Graphite electrodes. The process* is rather a specialty although the look & feel of the furnaces seem similar to Submerged Arc Furnaces used for producing Ferro Alloys and Silicon Metal. The furnaces can produce Titanium Slag of different grades namely:

• TiO₂ 85%
• TiO₂ 90%
• TiO₂ 92%

Easier to produce in the furnaces is the TiO2_85% slag. The higher grades need more careful process control. Higher furnace ratings are best done in DC Arc furnaces instead of conventional AC Arc furnaces which do well till small sizes without any issues. But beyond a certain capacity, DC does better than AC. Pig Iron is a by-product thereby making Ti-Slag a uniquely positioned product is envisage as the by-product too is saleable at good rates, where all other bulk processes have not much use for Slags or by-products other than cheap sale or dispose-off.

(*) RgCON can offer technology of AC & DC Arc Furnaces for Ti-Slag in collaboration with partner companies.

RgCON will be venturing into Copper Blister & Cobalt Smelting furnaces*. Copper is the industry’s gold as the popular caption goes. Cobalt has very special applications where it is almost irreplaceable. Copper & Cobalt smelting can be done in RgCON’s AC SAFs. The furnaces use prebaked Graphite electrodes.

(*) RgCON can offer technology for Copper-Cobalt Smelting in collaboration with partner companies.

Carbides can be of various types and compositions. The Carbides known in our field of work are Calcium Carbide and Silicon Carbide*. Calcium Carbide is more of an intermediary product if used to produce Silicon Calcium, has applications in manufacture of acetylene gas, fertilizers, steel making. The furnaces use self-baked Soderberg electrodes. Silicon Carbide on the other hand is an entirely different process with a batch process rectangular furnace with anode-cathode principle. Silicon Carbide has applications in float glass production, abrasives, refractories, electronics, ignitors in gas heaters, glass melting, non-ferrous metals. Calcium Carbide can be produced in RgCON ’s AC SAFs and Silicon Carbide can be produced in furnaces designed by RgCON in collaboration with partner companies.
