Ferro Molybdenum

The production of Ferro Molybdenum starts with the mining of Ferro Molybdenum and it is sent to roasting and smelting process. Roasting of Molybdenum concentrate results in molybdenum oxide and is re-roasted to create molybdenum trioxide that contains 53% of molybdenum. It is then blended with several materials such as iron core concentrate, ferrosilicon, lime, aluminium powder and steel crap. The blended product is smelted for about 20-40 minutes and that results in creating ferromolybdenum and slag. Finally, it is broken down as per the requirements and is packed carefully.


Ferro Molybdenum is mostly used in the manufacturing of ferroalloys. Depending on the presence of the molybdenum composition, it is used in the manufacturing of a wide range of products from power generators to vehicles.

It is used as a potent hardenability element and is present in the composition of numerous heat treatable alloy steels. It is an important constituent of HSLA steel (High-strength low alloy steel). Components with a high percentage of Ferro Molybdenum are used in machining equipment, screwdrivers, cylinder blocks, piston rings and so on.

The inclusion of Ferro Molybdenum in alloys can increase corrosion resistance.

Ferro Manganese is prepared by mixing oxides such as Manganese dioxide and ferrous oxide along with high carbon content in an electric arc furnace or in a blast furnace. The carbon usually used is coke and coal. This causes a carbothermic reduction and it results in the production of Ferromanganese. Generally, Ferromanganese is categorised into three types – Standard ferromanganese, medium-carbon ferromanganese, low-carbon ferromanganese.


The major usage of ferromanganese is in steel production as it acts as a great deoxidant. It helps in creating quality steel. Also, when combined with sulphur it prevents the formation of iron sulphides which can lead to surface cracking. It is also one of the cheapest alloy element that can improve mechanical properties including toughness and strength.

Ferroalloy industry is closely linked with iron and steel industry. Silicon is basically used in deoxidation of steel and as an alloy during casting of iron. Silicomanganese can be manufactured with low and medium grades of Manganese Ore with lesser cost when compared to High Carbon Ferro Manganese which needs very high-grade Manganese Ores.

Silico Manganese adds additional silicon which is a stronger deoxidizer and also helps in improving some important properties of steel and increases the strength of steel. Usage of silicomanganese adds less carbon to steel when compared to standard High Carbon Ferro Manganese.

Silicomanganese is prepared from manganese ore, quartz, ferromanganese slag and fluxes that mostly comprises of calcite or dolomite. The process is started by heating and pre-reduction that causes reduction of manganese oxide to manganese monoxide and also iron oxides to metallic iron. Next, the liquid slag forms and the reduction of manganese oxide occurs. The slag formed is used in silicomanganese production as a source of manganese.


Silicomanganese is used in the chlorine industry for bleach manufacturer. It improves tensile strength, toughness, workability and resistance to abrasion. It generally reacts with the remaining of sulphur in steel and reduces the possibility of hot shortness.
Ferro Vanadium

Ferro Vanadium is formed by merging of iron and vanadium. The source of ferrovanadium is manganite ore containing titanium. The process starts by melting scrap iron and it is added with aluminium, vanadium pentoxide along with a flux such as calcium oxide. The process takes place in an electric arc furnace. The mixture is kindled till the reaction attains its end stage.


Ferrovanadium is used as a steel additive which makes the steel rust resistant. It is also used in the production of spring and high-speed tool steels. For bonding titanium to steel, vanadium foil plays an important role. Vanadium is also used in nuclear applications because of its low fission neutron cross section.

Ferroboron can be manufactured by two processes. One is by carbothermic reduction of boric acid in the presence of carbon steel in an electric arc furnace. The second method is by aluminothermic reduction of boric acid in the presence of iron or magnesium resulting in a low carbon proportion.


It is used in hot spray painting and also in the manufacturing process of various amorphous metals. It also helps in the improvement of steel and nitrogen savaging It is also commonly used in the production of magnet due to its magnetic susceptibility to the final product. Hardenability of C-Mn and low alloy steels can be achieved by using ferroboron.

There are two famous methods for producing ferrosilicon. One method is by reduction of sand or silica using coke and further reacting it with iron.

The second method is by melting steel scrap and quartz along with a reductant in a submerged electric arc furnace. This will result in a hot liquid metal alloy, which is then collected in a sandbed and cooled down. It is essential to add large amounts of silica in order to eliminate the formation of silicon carbide.


  • It is used in numerous processes such as casting, melting and atomization.
  • It also serves as a basic raw material for mineral processing, inoculation, melting rod industry and so on.
  • It is used in the steel melting process in coating and deoxidation process. It is also a source of pure silicon.
  • It is utilized in the manufacturing of silicon steels which is especially used in electromotors and transformer cores.
Ferro Silicon Magnesium

Manufacturing of Ferro Silicon Magnesium Calcinated dolomite is reduced through the silicothermic or alumino silicothermic process. The reducing elements involved in the process include ferrosilicon or a mixture of ferrosilicon and aluminium. The process results in the production of magnesium and it is reacted with ferrosilicon to get magnesium silicide. Another method to manufacture ferrosilicon magnesium is to immerse the magnesium in molten ferrosilicon and to heat it. This creates high-quality ferrosilicon magnesium.


It is mainly used in the production of several varieties of ductile cast iron and silicon It is also used to transform graphite flakes to spheroids. It is also used in the manufacturing of steel due to its low carbon content.
Silicon-Based Inoculants

Inoculants are a family of ferrosilicon alloys containing elements like calcium, cerium, zirconium, barium, sulphur, strontium, manganese and oxygen. The type of the inoculant to be used is selected based on the application.


Inoculants are used to prevent chilling effect and blowholes Inoculants can be used to produce special grey iron casting comprising boron, vanadium and chromium. It is used to create A grade pyrolytic graphite carbon structure in cast iron.
Steel ingots

Steel ingots can be created by using a wide range of moulds but usually, big end down mould is used. This mould is large and is usually composed of high-quality carbon iron. The steel mixture is poured into the mould and the ingot is let to solidify. This phase of the process takes more time and once it is completed, the product is treated with hot rolling to remove solid inclusions and discrepancies of porosity.


Steel ingots can be used in a lot of places and for a wide range of applications.
