Ferroalloys are products added to molten iron during the steelmaking process as deoxidizers and element additives to impart specific characteristics or meet certain requirements. They are primarily intermediate alloys composed of iron and one or more elements and are mainly used in iron and steel smelting. In the iron and steel industry, all intermediate alloys used for steelmaking, whether they contain iron or not (such as calcium silicon alloys), are referred to as "ferroalloys."
The main elements in ferroalloys generally have high melting points, or their oxides are difficult to reduce, making it challenging to produce pure metals. However, when these elements are combined with iron, they become easier to reduce and smelt. In iron and steel smelting, the iron in ferroalloys is not only harmless but also advantageous due to its easy dissolution into molten steel. Therefore, deoxidation and alloy addition during the steelmaking process are mostly carried out using ferroalloys. It is worth noting that ferroalloys themselves are generally brittle and cannot be used as metallic materials.
Ferroalloys have various uses in the iron and steel industry:
Deoxidizers: Used to remove oxygen from molten steel during the steelmaking process. Some ferroalloys can also remove other impurities from steel, such as sulfur and nitrogen. Silicon manganese, ferromanganese, and ferrosilicon are the most commonly used deoxidizers, while aluminum (ferroaluminum), calcium silicon, and silicon zirconium are strong deoxidizers.
Alloy Additives: Alloying elements are added based on the composition requirements of the steel grade to improve the properties of steel. Commonly used alloy additives include ferromanganese, ferrochromium, ferrosilicon, ferrotungsten, ferromolybdenum, ferrovanadium, ferrotitanium, and ferronickel. These ferroalloys are further classified into many grades based on alloy element content or carbon content, depending on steelmaking needs, with strict limits on impurity content.
Inoculants: Added to molten iron before cast iron pouring to improve the crystalline structure of castings.
Reducing Agents: Used in the metallothermic reduction process to produce other ferroalloys and non-ferrous metals, as well as serving as alloy additives for non-ferrous alloys. Additionally, ferroalloys are used in small quantities in the chemical industry and other industries.
For the testing of ferroalloys, it primarily includes chemical composition analysis, physical performance testing, and mechanical performance testing. Among these, chemical composition analysis is a fundamental item in ferroalloy testing. Equipment such as spectrometers and chemical analyzers can precisely determine the content of various elements in ferroalloys. Mechanical performance testing includes tensile tests, compression tests, and Brinell hardness tests to evaluate the mechanical properties of ferroalloys.
The following are standard methods related to ferroalloy testing:
GB/T 14984.1-2010 Ferroalloys-Terminology-Part 1: Materials
GB/T 13247-2019 Ferroalloy Products-Sampling and Testing Methods for Particle Size
GB 28666-2012 Emission Standards of Pollutants for the Ferroalloy Industry
GB/T 6394-2002 Method for Determination of Average Grain Size of Metals
GB/T 10561-2005 Steel-Determination of Content of Non-Metallic Inclusions-Microscopic Examination Method Using Standard Diagrams (Note: Specifically mentioned in the standard)
GB/T 228.1 Metallic Materials-Tensile Testing at Room Temperature
GB/T 226-2015 Steel-Macrostructure and Defect Etching Inspection Method
GB/T 11170-2008 Stainless Steel-Determination of Multi-Element Content-Spark Discharge Atomic Emission Spectrometry (Conventional Method)
GB/T 11261-2006 Iron and Steel-Determination of Oxygen Content-Pulse Heating Inert Gas Fusion-Infrared Absorption Method
The above content comprehensively introduces the definition, uses, testing items, and related standard methods of ferroalloys, providing important references for the application of ferroalloys in the iron and steel industry.
