The Future Development Direction Of Ductile Iron
Dec 05, 2018

Energy-saving requirements result in essentially redesigning the part 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. 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 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 beneficial to help the factory build power in this area, although the valuation will improve and improve. However, the temperature of the molten iron is lower than 1450"C, and the RG value is very poor. The RG value is almost unchanged. It can be obtained from Table 3: the quality index of the cast iron is 18% higher than that of the metallurgical coke smelting. The relative hardness is reduced by 3%.
