A freecutting semi-killed steel has been investigated and produced successfully in industrial-scale furnace,and the oxygen activity measured in ladles was at the level of 150～250 ppm.
３７，设计了新钢种的化学成分，在工业炉中炼成半镇静易切削钢，钢包中氧活度在１５０～２５０ｐｐｍ范围内。
non-piping steel
无缩孔钢, 半镇静钢
What do the terms "rimming steel", "fully killed steel"and "semi-killed steel"refer to?
这3个术语"沸腾钢"、"镇静钢"、"半镇静钢"指的是什么?
In the case of semi-killed or balanced steel, more deoxidation is carried out than with rimming steel, but not enough to completely "kill"the steel.
半镇静钢比沸腾钢脱的氧多，但又不至于使钢完全"镇静"。
I suppose semi-killed steel must be just between these two in every aspects.
我想半镇静钢可能在各方面都介于这两者之间吧?
so that only a very small pipe is formed, hence the name "balanced steel".Its yield of good steelis about 85 %.
结果只有很小的缩孔出现，因而获名"半镇静钢"。其成材率大约为85％。
dead-melted steel
