Brief Introduction of Ductile Iron Casting
Ductile iron is a high-strength cast iron material developed in the 1950s, whose comprehensive properties approach those of steel. It is used to cast some complex parts with high strength, toughness, wear resistance, and other requirements. The phrase "replacing iron with steel" mainly refers to ductile iron. Ductile iron is obtained by ballizing and inoculation treatment to obtain spherical graphite, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, thus obtaining a higher strength than that of carbon steel.
Ductile iron casting parts are now used in almost all major industrial sectors, where high strength, ductility, toughness, wear resistance, resistance to severe thermal and mechanical shock, high or low temperature resistance, corrosion resistance, and dimensional stability are required. There are many grades of ductile iron, providing a wide range of mechanical and physical properties.
Application of Ductile Iron Casting Parts
1. Mechanical manufacturing industry：
Because of its high strength, high wear resistance and low cost, ductile iron is widely used in various types of mechanical parts, such as machine tools, drilling machines, milling machines, grinding machines, casting machinery and so on.
2. Automobile manufacturing industry
Due to its high strength, rigidity and durability, ductile iron can be applied to various automotive parts, such as crankcase, engine block, steering arm, wheel hub, etc.
3. Construction engineering industry
Ductile iron is widely used in the field of construction in various structural supports and joints. For example, the bolt connection in the building steel structure, the connection of the building column, the steel support of the external wall retaining wall, and the building roof with long span and large span.
4. Water conservancy engineering industry
Ductile iron, as a common material in the water conservancy engineering industry, has a very wide range of applications, such as gates, water pipes, pumps and sluice gates, which can make hydraulic equipment more durable and reduce maintenance costs.
5. Road traffic industry
Ductile iron materials are widely used in the road traffic industry, such as for the manufacture of railway tracks, road drains and highway guardrails, etc., and the effect of the material is better under the impact, vibration and other complex environments.
