Chuctile iron manufacturing and process advantages
Ductile iron, also known as ductile casting, is a casting material. The main raw materials of ductile casting are cast iron mother alloy (cast iron, steel, scrap steel, etc.), spherical agent and point-saving agent, etc. Its spherical graphite structure is different from the sheet graphite structure of ordinary gray cast iron. The spherical structure of ductile cast iron enhances the strength and toughness of the material.
Performance superiority of ductile cast iron
The performance superiority of ductile cast iron is mainly reflected in the following aspects:
1. High utilization rate of matrix strength:
The spherical structure of ductile iron can resist fracture under pulling force, allowing ductile iron to withstand greater load compared with ash cast iron. Meanwhile, the bending strength of the ductile iron is also relatively increased.
2. High toughness:
The high toughness of ductile iron allows the material to withstand greater load and impact when working, but also allows ductile iron to be used at low temperatures. This is because the spherical structure prevents the crack expansion, which gives the ductile iron a strong toughness.
3. Good corrosion resistance:
The surface of ductile iron has dense structure and good corrosion resistance. It is often used to manufacture some corrosion-resistant equipment.
In short, ductile iron is a casting material with high strength, high toughness and corrosion resistance, which is widely used in aviation, aerospace, automotive, machinery and other fields. The performance superiority of ductile iron stems from the high utilization rate, high toughness and good corrosion resistance of its matrix strength.
