ferrous intermediate alloy

Intermediate ferroalloy refers to intermediate alloy(s) composed of iron and one or several elements. It is usually based on a metal, and one or several elements are added to it to solve the problem that the element is easy to burn, the high melting point is not easy to melt, and the density It is a kind of additive functional material that is prone to problems such as segregation or special alloys used to improve the properties of alloys. Common intermediate iron alloys are ferro manganese, ferro silicon, etc.

Intermediate ferroalloys are mainly used in steel smelting. The main uses include: as a deoxidizer in steel production. In steelmaking, alloys are added to remove harmful impurities such as phosphorus and sulfur in molten iron, so that molten iron can be converted into molten steel. In this process, there is a phenomenon of peroxidation. Additives rich in oxygen-loving elements added in the steelmaking process are called deoxidizers. Common deoxidizers are calcium silicon, silicon barium, ferrosilicon barium, ferro silicon, medium-carbon ferro manganese, etc.; used as alloying agents in steelmaking. The alloying elements in alloy steel are realized by adding iron alloys. Iron alloys used to adjust alloying elements in steel are called alloying agents for steelmaking. Commonly used elements are Si, Mn, Cr, W, V, Ti, Nb, Ni, Al, etc. Commonly used alloys are: ferrosilicon, silicon manganese, ferromanganese, ferrochromium, silicon chromium, ferrotungsten, ferrovanadium, titanium Iron, ferronickel, ferroniobium, ferromanganese, etc.; used as an inoculant and nodularizer for casting. In the casting process, some iron alloys containing appropriate amount of Re (general term for rare earth elements), Mg, Ca, Ba, Si and other elements are added before pouring. These elements can make the carbon in the cast iron water graphitized and uniformly dispersed as soon as possible, and have both The role of degassing, desulfurization and phosphorus. Improve the mechanical strength and toughness of castings. Commonly used iron alloys include rare earth silicon calcium magnesium and rare earth ferrosilicon, silicon magnesium iron (ie nodularizing agent), low barium calcium calcium ferrosilicon (ie inoculant) and so on.
