Do you know what ductile iron is?

Ductile iron is a high-strength cast iron material with comprehensive properties close to steel, developed in the 1950s. It has been successfully used to cast parts that are subject to complex stresses and require high strength, toughness, and wear resistance due to its excellent performance. The term 'replacing steel with iron' mainly refers to ductile iron, which has rapidly developed into the most widely used cast iron material after gray cast iron.

Features of ductile iron solidification, features of riser design

Features of ductile iron solidification, features of riser design

Generally speaking, the tendency of shrinkage cavities and porosity in ductile iron castings is much greater than that in gray iron castings, and preventing shrinkage defects is usually a very difficult problem in process design. In this regard, the experience summarized from actual production is very inconsistent, and each has its own views: some people believe that ductile iron castings can only be produced with small risers to produce qualified castings, sometimes without risers; some people believe that the principle of sequential solidification should be followed, and large risers should be placed at the solidification site to supplement the volume shrinkage of the casting during solidification.

Main properties of ductile iron

Main properties of ductile iron

Main properties: Ductile iron castings are used in almost all major industrial sectors, requiring high strength, plasticity, toughness, wear resistance, severe heat and mechanical shock resistance, high and low temperature resistance, corrosion resistance, and dimensional stability. To adapt to these changing conditions of use, ductile iron has many grades, providing a wide range of mechanical and physical properties.

What are the casting processes?

The main casting processes include: metal smelting, model making, pouring solidification, and demolding cleaning. The main materials used in casting include cast steel, cast iron, and cast non-ferrous alloys (copper, aluminum, zinc, lead, etc.).

Casting production process

Casting production process

Casting production is a complex multi-stage combination process, including the following main processes: production process preparation, according to the part drawings, production batches and delivery deadlines to be produced, develop production process plans and process documents, and draw casting process drawings.
