Get PriceThe ferro-titanium alloy with titanium content of 20-75 wt is produced with recovered titanium and sponge titanium as raw material, which, after analysis, crushing, deoiling and roasting, is smelted together with low-carbon steel in a certain ratio inside the crucible of vacuum induction furnace. The said method can smelt ferro-titanium alloy of different quality requirement.
Get PriceFerro-alloys are usually produced by the reduction of a metallic ore generally oxide by carbon with the addition of electric energy in a Submerged Arc Furnace smelting process or by metals metallo-thermic reduction, usually aluminium or silicon. High carbon ferro-manganese is produced by the reduction of manganese ore by carbon, in electric submerged-arc furnaces or in blast furnaces.
Get PriceAs mentioned above, ferro-alloys can be divided into two main categories bulk alloys and special alloys. Bulk ferro-alloys ferro-chrome, ferro-silicon, ferro-manganese, silico-manganese and ferro-nickel. Compared to bulk ferro-alloys, the production rate of special ferro-alloys is rather small.
Get PriceHowever, Ferro-alloys are usually produced by the reduction of a metallic ore generally oxide by carbon with the addition of electric energy in a Submerged Arc Furnace smelting process or by metals metallo-thermic reduction, usually aluminum or silicon. The submerged arc process is a reduction smelting operation.
Get PriceJul 10, 2018 Ferro-chrome Fe-Cr is an alloy comprised of iron Fe and chromium Cr used primarily in the production of stainless steel. The ratio in which the two metals Fe and Cr are combined can vary, with the proportion of Cr ranging between 50 and 70 .

Get PriceIndia produces 3.5 million tonne mt of ferro alloys and consumes around 2.3 mt. The country exported 1.3 mt of ferro alloys, earning a foreign exchange of around Rs 8,900 crore. Indias production of around 3.5 mt of ferro alloys consists of one million tonne of ferro chrome FeCr and 2.5 mt of manganese alloys.
Get PriceMar 02, 2020 Some metal alloys occur naturally and require little processing to be converted into industrial-grade materials. Ferro-alloys such as Ferro-chromium and Ferro-silicon, for instance, are produced by smelting mixed ores and are used in the production of various steels. Yet, one would be mistaken to think that alloying metals is a simple process.
Get PriceCompared to bulk ferro-alloys, the production rate of special ferro-alloys is rather small. Special ferro-alloys ferro-vanadium, ferro-molybdenum, ferro-tungsten, ferro-titanium, ferro-boron, and ferro-niobium are mostly used in the iron, steel and cast-iron industries. ... a - Process by which metal is smelted in a refractory-lined cup ...
Get PriceJun 19, 2018 Production of Ferro- Manganese Ferro-manganese Fe-Mn is an important additive used as a deoxidizer in the production of steel. It is a master alloy of iron Fe and manganese Mn with a minimum Mn content of 65 , and maximum Mn content of 95 .
