平炉钢

并且发现平炉钢中硫含量较高、其处理效果更好。

The treatment of open-hearth steel with high sulphur level was found to be more effective .

平炉钢用炉外精炼剂的研究

Study on Additive of Secondary Refining Used in Open Hearth Steel

真空碳脱氧碱性平炉钢大型电站转子锻件质量的研究

Quality of Heavy Rotor Forgings for Power Plants Studied by VCD Process to BOH Steel

我想第二种分类方法较简单。按冶炼方法，钢可分为平炉钢、转炉钢和电炉钢。

I think the second way to classify steels is simple . By refining methods steels can be divided into three classes : open-hearth furnace steel , converter steel , and electric furnace steel .

本文在真空碳脱氧碱性平炉转子钢的试验中，就非金属夹杂物的特性，分析了真空碳脱氧这一新的工艺对转子锻件中非金属夹杂物的影响。

This paper analyzes the effect of vacuum carbon deoxidation process on the characteristic of the non-metal inclusion in the rotor forgings which were made of BOH steel by vacuum carbon deoxidation .
