The stainless steel out \ | gassing rates can be reduced greatly by high temperature degassing technology in a vacuum furnace.
真空炉高温除气工艺可以大大降低不锈钢出气率。
Nevertherless, basic oxygen furnace process with heated ladle refining and vacuum degassing may also be considered as acceptable.
不过，带加热钢水包精炼及真空除气的氧气顶吹转炉工艺也可接受。？
The tube bloom made by this method has given out the same physical and chemical test results as that made by basic open-hearth furnace + vacuum degassing process + ESR process.
采用碱性平炉+ ESR(电渣重熔)法生产高强韧管坯，能完全满足管坯的各项技术要求，各项理化检测结果与采用碱性平炉+真空除气+ ESR法生产的同类管坯水平基本相当。
