Content analysis of ferrochromium nitride in global In the world today, ferrochromium nitride is mainly produced by vacuum heat treatment; the result is a sintered product with a high nitrogen content. Sometimes, this material is remelted to obtain a dense ingot, but with a low nitrogen content. The raw material for nitriding is either low-carbon [...]
Ferromolybdenum Introduction Ferromolybdenum is an alloy formed by combining iron and molybdenum. It is an extremely versatile alloy used primarily in high-strength low alloys and stainless steels. It has numerous beneficial properties and can be used even in cast irons, some high-speed tool steels, and superalloy applications. Adding it to a material helps to [...]
Ferrochromium Ferrochrome (FeCr) is an alloy of chromium and iron containing 50% to 70% chromium by weight. Ferrochrome is produced by electric arc carbothermic reduction of chromite. Most of the world's ferrochrome is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources. Increasing amounts are coming from Russia and China. The [...]
Ferrochromium nitride Ferrochromium nitride is a unique alloying material suitable for use in the production of corrosion-resistant nitrogen steel. Ferrochromium nitride has been produced since the 1930s, when it was employed primarily to introduce considerable quantities of nitrogen in chrome steel. In the first research on alloying and nitriding chromium alloys, the ingot structure of [...]
High carbon ferromanganese Manganese alloys are mostly used in steelmaking and foundry. Today 30 % of the manganese used in steelmaking is still used for its properties as a deoxidizer and a sulphide. In this last case it combines with sulphur avoiding the formation of iron sulphides. Sulphides are low melting point phases which become [...]
Low carbon ferromanganese Manganese alloys are mostly used in steelmaking and foundry. Today 30 % of the manganese used in steelmaking is still used for its properties as a deoxidizer and a sulphide. In this last case it combines with sulphur avoiding the formation of iron sulphides. Sulphides are low melting point phases which become [...]
How many kinds of Special Ferroalloy The main categories of special ferroalloy as follows: 1. High carbon ferrochrome. The carbon content of high carbon ferrochrome is 6.0% to 10.0%. Smelting with ore furnace, and using chrome ore as raw material, coke as reductant, silica as flux. 2. Medium and low carbon ferrochrome. At present, the main [...]
Ferroalloy types and applications The main categories of common ferroalloy as follows: 1. Ferrosilicon. That is silicon and iron combined ferroalloy, according to the silicon content, there are 45%, 65%, 75% and 90% grades, it is one of the main steel deoxidizer and alloy agent. 2. High-carbon ferromanganese. Carbon content is generally 7.0%, up [...]
How to calculate ferromanganese production Physical output Physical output refers to the actual weight of the ferromanganese that is produced by the blast furnace during a certain period of time, and shall be counted according to the classification of different grades. Ferromanganese that does not conform to industry standards or specific supply standards is [...]
Ferrosilicon Introduction Ferrosilicon is a ferroalloy - an alloy of iron and silicon. Its CAS number is 8049-17-0. The average silicon content varies between 15 and 90 wt%. It contains a high proportion of iron silicides. Ferrosilicon is produced by reduction of silica or sand with coke in presence of iron. Ferrosilicon is known [...]
