摘要
简介ＲＨ循环真空除气（ＲＨ）的工艺特点及在设备上的改进措施，对其喷粉，脱碳，脱氧，脱氮的多种工艺和冶金效果进行了评述，采用ＲＨ的新技术可以生产极低碳和超纯净钢。
This paper introduced the technological features of RH degassing process and the improving measures for the equipment, evaluated the metallurgical effects of powder injection decarbonization, deoxidation and denitrification in it. The new technologies of RH can be used to produce ultra-low and ultra-pure steel.
