SAE J434 D700铸态材料熔炼方法探索

Exploration of melting methods for SAE J434 D700 as-cast materials

介绍了SAE J434 D700材料特性,深入研究了化学成分对基体组织的影响,制定了通过调整C、Si、Mn、P、S五大基本元素和合金元素Mo、Cu、Sn的配比,以冲入球化处理方式、二次孕育处理的铸态熔炼方法,此方法实施后获得性能良好的SAE J434 D700材料,各项性能指标均符合技术要求。

The characteristics of SAE J434 D700 material have been introduced,and the influence of chemical composition on the matrix structure has been deeply studied.A casting melting method has been developed by adjusting the ratio of the five basic elements C,Si,Mn,P,S,and alloy elements Mo,Cu,and Sn.The method has been carried out through injection spheroidization treatment and secondary inoculation treatment.After implementation,the SAE J434 D700 material with good performance has been obtained,of which all performance indicators meet the technical requirements.
