2.Meihong Machinery Cast iron: an iron-carbon alloy containing more than 2% carbon. Industrial cast iron generally has a carbon content of 2.5% to 3.5%. Carbon is mostly in the form of graphite in cast iron, and sometimes in the form of cementite. In addition to carbon, cast iron also contains 1% to 3% of silicon, as well as manganese, phosphorus, sulfur and other elements. Alloy cast iron also contains elements such as nickel, chromium, molybdenum, aluminum, copper, boron, and vanadium. Carbon and silicon are the main elements that affect the microstructure and properties of cast iron. Cast iron can be divided into:1 gray cast iron. The carbon content is high (2.7%~4.0%), the carbon is mainly in the form of flake graphite, and the fracture is gray, referred to as gray iron. Low melting point (1145~1250 °C), small shrinkage during solidification, compressive strength and hardness close to carbon steel, good shock absorption. Since the flake graphite exists, the wear resistance is good. Casting performance and cutting processing are better. It is used to manufacture structural parts such as machine bed, cylinder and box. Its brand number is followed by "H" with two sets of numbers. For example: HT20-40 (the first number indicates the lowest tensile strength and the second number indicates the minimum bending strength).2 white cast iron. Carbon and silicon content are low, carbon is mainly in the form of cementite, and the fracture is silvery white. When the solidification shrinks, it is easy to produce shrinkage cavities and cracks. High hardness, brittleness, and can not withstand impact loads. Used as a blank for malleable cast iron and as a wear-resistant part.3 malleable cast iron. Obtained by annealing the white cast iron, the graphite is distributed in a flocculent shape, referred to as tough iron. It has uniform texture, wear resistance and good plasticity and toughness. Used to make parts that are complex in shape and can withstand strong dynamic loads.is focused on Cast of the first choice, Cast net 5ft, Flexible operation Cast, http:foundryfrontier.com and other projects. even though in the rapid development of the project ,Meihong Machinery always stressed the balance between external opportunities and internal management, attaches great importance to the core competitiveness of enterprises to cultivate and shape.
