Ferroalloys, a broadly defined ferroalloy is a product that is used as a deoxidizer, elemental additive, etc. in steelmaking to add iron to certain properties or to meet certain requirements.
Property: The main element of the ferroalloy generally has a high melting point, or its oxide is difficult to reduce, and it is difficult to refine the pure metal. If it is together with the iron, it is easier to reduce the smelting. The use of ferroalloys in iron and steel smelting, in which iron is not only harmless, but because of the fusing of molten steel is more favorable. Therefore, deoxidation and alloying in the steelmaking process are mostly added in the form of iron alloys. Iron alloys are generally brittle and cannot be used as metal materials.
Purpose: As a deoxidizer for steelmaking, silicon manganese, ferromanganese and ferrosilicon are the most widely used . As strong deoxidizers, aluminum (aluminum iron), silicon calcium, silicon zirconium, etc are used . Commonly used alloy additives are: ferromanganese, ferrochromium, ferrosilicon, ferrotungsten, ferromolybdenum, ferrovanadium, ferrotitanium, ferronickel, niobium (neodymium) iron, rare earth iron alloy, ferroboron, ferrophosphorus and so on. A variety of ferroalloys, in accordance with steelmaking needs, are regulated in many grades based on the content of alloying elements or the level of Carbon contained, and the impurity content is strictly limited. Ferroalloys containing two or more alloying elements are called composite ferroalloys. The use of such ferroalloys can add deoxidizing or alloying elements at the same time, which is beneficial to the steelmaking process and enables the more comprehensive and efficient utilization of symbiotic ore resources. Commonly used: manganese silicon, silicon calcium, silicon zirconium, silicon manganese aluminum, silicon manganese calcium and rare earth ferrosilicon.
