primary graphite

The magnesite graphite brick has a good slag resistance because the magnesia is the primary component.

由于镁砂为主要成份,使该镁碳砖具有良好的抗渣侵蚀性能.

The analysis of the structure and break of the minor diameter cast iron bars shows that developed primary austenite dendrites distribute in framework; With the high-power electron microscope to observe the D-type graphite between dendrites, the graphite is approximately worm-shaped or coral-shaped.

对小直径铸铁型材的组织及断裂行为分析表明：发达的初生奥氏体枝晶呈框架结构分布；枝晶间的D型石墨在高倍电镜下观察石墨的形状近似呈蠕虫状或珊瑚状。

With the increase of Al content, the graphite content and eutectic graphite of solidifying structures deduce, graphite in primary phase has a tendency of spherical transformation.

随着Al含量的增加，凝固组织中的石墨含量有所降低，共晶石墨减少，初生相中石墨占多数并有球化的趋势；

The increase of carbon equivalent is primary reason for graphite floatation.

碳当量高是引起石墨漂浮的主要原因.
