Physical Properties Of Casting Ferro Manganese
An iron-carbon alloy with a carbon content of over 2%. The general carbon content of industrial cast iron is $number. Carbon in cast iron in the form of graphite, and sometimes in the form of cementite exist. In addition to carbon, cast iron also contains $number silicon, as well as manganese, phosphorus, sulfur and other elements. Alloy cast iron also contains nickel, chromium, molybdenum, aluminum, copper, boron, vanadium and other elements. Carbon and silicon are the main elements that influence the microstructure and properties of cast iron. Cast iron can be divided into: gray-cast iron. High carbon content (2.7%~4.0%), carbon mainly in flake graphite form exists, the fracture is gray, referred to as gray iron. Low melting point (1145~1250℃), shrinkage in the solidification of small, compressive strength and hardness near carbon steel, good damping.Casting Ferro Manganese
Used for manufacturing machine tool bed, cylinder, box and other structural parts. White cast iron. Carbon, silicon content is low, carbon mainly in cementite form exists, the fracture is silvery white. Shrinkage in the solidification, easy to produce shrinkage, cracks. High hardness, large brittleness, can not withstand impact load. It is used as the billet of malleable cast iron and the making of wear-resisting parts. Malleable。 It was obtained by annealing treatment of white cast iron, and the graphite showed a group floc distribution, referred to as ductile iron. Its organization performance is uniform, wear-resisting, have good plasticity and toughness.
Used to manufacture parts with complex shapes and can withstand strong dynamic loads. Iron。 The gray cast iron is obtained by spherical process, and the precipitated graphite is spherical, which is referred to as ductile iron. Higher strength, better toughness and plasticity than ordinary gray cast iron. For the manufacture of internal combustion engines, auto parts and agricultural machinery. Vermicular Graphite cast iron. The ash cast iron is obtained by the creep treatment and the precipitated graphite is worm-like.Casting Ferro Manganese
The mechanical properties are similar to ductile iron, and the casting performance is between gray cast iron and ductile iron. Parts for making automobiles. Alloy cast iron. Ordinary cast iron is obtained by adding proper amount of alloying elements (such as silicon, manganese, phosphorus, nickel, chromium, molybdenum, copper, aluminum, boron, vanadium, tin, etc.). alloying elements make the matrix structure of cast iron change, which has the corresponding heat-resistant, wear-resisting, corrosion-resistant, low-temperature or non-magnetic characteristics. Used in the manufacture of mining, chemical machinery and instrumentation, instrumentation and other components.Casting Ferro Manganese
