采用中频熔炼、离心雾化凝固冷却得到铸态低碳铸钢丸，并对此进行相应回火处理得到不同硬度及寿命的低碳铸钢丸。
In this thesis, series of low carbon cast steel shot were successfully obtained by medium-frequency melting and centrifugal atomization technologies and temper were performed.
在雾化过程中，有50%左右的氧化发生在熔炼阶段。
In the atomizing process, about 50% of oxidation takes place a...
如果合金本身对氧非常敏感，则不仅在雾化时要采取措施，在熔化时最好也采用真空熔炼。
If the alloy is in itself sensitive to the oxygen, then not only in atomization time must take the measure, when melting should better also use the vacuum melting.
