  4. Easy to use and low consumption.Adopt high strength moisture-proof packing, can directly into the furnace.

Ferro Vanadium

Ferrovanadium is a kind of ferroalloy, which can be obtained by reducing vanadium pentoxide with carbon in an electric furnace, or by reducing vanadium pentoxide with silicon thermal method in an electric furnace.It is widely used as an element additive in smelting vanadium alloy steel and alloy cast iron.In recent years it has been used to make permanent magnets.

Ferro Vanadium is used in large variety of steels, including the constructional alloy grades, carburizing steels, rail steels, die steels, and the super 12% stainless steels. FeV is widely used to increase the steels strength to weight ratios.

Ferrovanadium (FeV) is an alloy formed by combining iron and vanadium with a vanadium content range of 35%-85%. The production of this alloy results in a grayish silver crystalline solid that can be crushed into a powder called “ferrovanadium dust”.Ferrovanadium is a universal hardener, strengthener and anti-corrosive additive for steels like high-strength low-alloy steel, tool steels, as well as other ferrous-based products. It has significant advantages over both iron and vanadium individually. Ferrovanadium is used as an additive to improve the qualities of ferrous alloys. One such use is to improve corrosion resistance to alkaline reagents as well as sulphuric and hydrochloric acids. It is also used to improve the tensile strength to weight ratio of the material. One application of such steels is in the chemical processing industry for high pressure high throughput fluid handling systems dealing with industrial scale sulphuric acid production. It is also commonly used for hand tools e.g. spanners (wrenches), screwdrivers, ratchets, etc.

Ferro Molybdenum

A ferroalloy of molybdenum and iron, generally containing 50 to 60 percent molybdenum, used as an alloy additive in steelmaking.Ferromolybdenum is an alloy of molybdenum and iron.Its main use is as an additive of molybdenum in steelmaking.Adding molybdenum into the steel can make the steel have uniform fine grain structure and improve the hardenability of the steel, which is beneficial to eliminate the temper brittleness.Molybdenum can replace part of tungsten in high – speed steel.Molybdenum, together with other alloying elements, is widely used in the production of stainless steel, heat-resistant steel, acid-resistant steel and tool steel, as well as alloys with special physical properties.Molybdenum is added to cast iron to increase its strength and wear resistance.

Ferromolybdenum is most commonly used in the production of ferroalloys for use in machine tools and equipment, military equipment, oil refinery pipelines, load-bearing components and rotary drills, depending on the content and range of molybdenum.Ferro molybdenum is also used in cars, trucks, locomotives, ships and so on.In addition, ferromolybdenum is used in stainless steel and heat resistant by synthetic fuels and chemical plants, heat exchangers, generators, refining equipment, pumps, turbine tubes, ship propellers, plastics and acids, and storage containers employed in steel.Tool steel has a high percentage of ferro molybdenum in the range for high speed machined workpieces, cold working tools, drill bits, screwdrivers, dies, chisels, heavy castings, ball and rolling mills, rollers, cylinders, piston rings and large drill bits.

Ferro Molybdenum is widely used in alloys of steel to increase the hardness and durability of stainless steel. Ferro-Molybdenum is helpful in improving the corrosion resistance of stainless steel. In iron, this product is effective in strengthening & hardening, which causes austenite to transform into fine pearlite/ banite.Ferro molybdenum is an important iron-molybdenum metal alloy, with a molybdenum content of 60-75%,It is the main source for molybdenum alloying of HSLA steel.

Vanadium Pentoxide

Vanadium in its pure form is a soft, grey, ductile element primarily derived from mined iron ore and steel slag. A small amount of Vanadium (typically 0.04 – 4% in steel composition) forms carbides in steel and promotes fine grain size, a process which imparts hardness, wear resistance, seismic resistance and increased strength to the steel.
Vanadium oxide is the inorganic compound with the formula V2O5. Commonly known as vanadium pentoxide, it is a brown/yellow solid, although when freshly precipitated from aqueous solution, its colour is deep orange. Because of its high oxidation state, it is both an amphoteric oxide and an oxidizing agent. From the industrial perspective, it is the most important compound of vanadium, being the principal precursor to alloys of vanadium and is a widely used industrial catalyst.
Vanadium pentoxide is widely used in metallurgy, chemical industry, mainly used in smelting ferrovanadium.It is used as alloy additive, accounting for more than 80% of the total consumption of vanadium pentoxide, followed by catalyst for organic chemical industry, namely catalyst, accounting for about 10% of the total, and used as inorganic chemicals, chemical reagents, enamel and magnetic materials, accounting for about 10% of the total.

Molybdenum

Molybdenum is a chemical element with the symbolMo and atomic number 42. The name is from Neo-Latinmolybdaenum, from Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores.[7] Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in 1778 by Carl Wilhelm Scheele. The metal was first isolated in 1781 by Peter Jacob Hjelm.[8]

Molybdenum does not occur naturally as a free metal on Earth; it is found only in various oxidation states in minerals. The free element, a silvery metal with a gray cast, has the sixth-highestmelting point of any element. It readily forms hard, stable carbides in alloys, and for this reason most of world production of the element (about 80%) is used in steel alloys, including high-strength alloys and superalloys.

Most molybdenum compounds have low solubility in water, but when molybdenum-bearing minerals contact oxygen and water, the resulting molybdate ion MoO2−
4 is quite soluble. Industrially, molybdenum compounds (about 14% of world production of the element) are used in high-pressure and hig

High /low carbon ferrochrome

A ferroalloy with chromium and iron as its main constituent.It is one of the main alloying agents used in iron and steel industry.Ferrochrome chromium containing 55% ~ 75%, according to the carbon content is divided into high carbon (C) (4% ~ 10%), middle carbon (C) (0.5% ~ 4%), low carbon (C) (> 0.15% ~ 0.5% ) and micro carbon (C)( 0.15% or less) .
Ferro Chrome is one of the most versatile and widely used alloying elements in steel. It imparts corrosion ad oxidation resistance, is a mild hardenability agent, improves resistance and promotes the retention of useful strength levels at elevated temperatures.
Adding chromium to steel can significantly improve the oxidation resistance and corrosion resistance of steel.Chromium is found in many steels with special physicochemical properties.Chromium in steel is added with ferrochrome.High carbon ferrochrome is used as an alloying agent for ball steel (0.5% ~ 1.45%Cr), tool steel, die steel (5% ~ 12%Cr) and high speed steel (3.8% ~ 4.4%Cr).The hardness and wear resistance of cast iron can be improved by adding chromium.High carbon ferrochrome and charge grade ferrochrome are widely used as charge for smelting stainless steel (AOD or VOD method) to reduce production cost.Medium and low carbon ferrochrome is used in the production of medium and low carbon structural steel, carburized steel, manufacturing gear, high pressure blower blade, valve plate, etc.Micro-carbon ferrochrome is used to produce stainless steel, acid-resistant steel, heat-resistant steel and electrothermal alloy, etc.
High carbon ferrochrome is one of the most common ferroalloys produced and is almost exclusively used in the production of stainless steel and high chromium steels. gas utilization. Recently installed plants display manageable risks in terms of environmental pollution and occupational health.
Low Carbon Ferrochrome is to regulate the ratio of Chromium in steel production without Carbon and other unwanted ingredients. Due to high quality it is a reliable and economical alternative instead of metallic Chromium in Superalloy production
