The development of nodular cast iron case

- Mar 13, 2021-

When the tonnage of ductile iron increases and the market penetration is amazing, this material must not be seen to reach its full potential. Based on this, cast iron plants that do not produce ductile iron now recommend that they reconsider the possibility in this respect. Energy-saving requirements have led to the basic redesign of parts to achieve light weight and high efficiency, which inevitably reminds designers to focus on materials. Ductile iron is increasingly considered to provide high strength-weight characteristics and can be produced at a relatively low cost.

  Therefore, it is expected that with the replacement of gray cast iron, malleable cast iron and silver castings, the production tonnage of ductile iron will continue to increase. Recent publications are beneficial to help manufacturers in this area, although the value will be improved and improved. However, when the temperature of molten iron is lower than 1450°C, the inoculation effect is very poor, and the RG value is almost unchanged.
