Future direction of ductile iron cast

- May 18, 2019-

Ductile iron cast is often used in the production of parts requiring high stress, strength, toughness and wear resistance, such as crankshafts, camshafts, and general machinery in automobiles, tractors, and internal combustion engines. Pressure valve, etc. It can also be used as a storage container for highly radioactive objects.


Future direction of ductile iron


The energy-saving requirements of ductile iron have led to the redesign of parts to achieve light weight and high efficiency, which inevitably reminds the designer to focus on the material. Ductile iron is increasingly believed to provide high strength-weight characteristics and can be produced at relatively low cost. This material must not be seen to reach its full potential. Based on this, cast iron plants that do not produce ductile irons suggest a good reconsideration of this possibility.


Therefore, it is expected that with the replacement of gray cast iron, malleable cast iron and cast silver parts, it is possible to see the continuous increase in the tonnage of ductile iron production. Published publications are good for helping the factory to work on this, although the valuation will improve and improve. However, after the temperature of molten iron is lower than 1450"C, the effect of gestation is very poor, and the RG value is almost unchanged. It can be obtained from Table 3: the quality index of cast iron is 18% higher than that of metallurgical coke by casting coke smelting, it is worth noting that The relative hardness is reduced by 3%.
