Machinery Castings are mainly used as a blank for machine parts, and some precision castings can also be used directly as parts of machines. It is a metal molded article obtained by various casting methods. Cast iron is a commonly used casting material in mechanical manufacturing, which is characterized by high hardness, high strength and poor toughness. It is mainly suitable for heavy-load transportation equipment, pressure vessels, large mechanical components and other fields. Common cast iron accessories include connecting rod, machine bed body, cast iron bracket, gear case, etc., suitable for the manufacture of parts under tensile pressure.
Cast iron is Ferric carbon alloy with carbon content above 2.11%. The carbon content of industrial cast iron is generally 2.5%~3.5%. Carbon exists in graphite form and sometimes in carburizing form. In addition to carbon, cast iron also contains 1%~3% silicon, as well as manganese, phosphorus, sulfur and other elements. Erosion-resistant cast iron also contains nickel, chromium, molybdenum, aluminum, copper, boron, vanadium and other elements. Carbon and silicon are the main elements affecting the microorganization and performance of cast iron. Cast iron is classified in the form of carbon existence, and can be divided into ash cast iron, white cast iron and hemp cast iron.
Cast iron and cast steel castings have been widely used in the following fields, including railway casting, automobile casting, construction machinery casting, forklift truck casting, agricultural machinery casting, and machinery castings.
