根据改进生产超低碳无间隙原子钢工艺控制的需要，在英国兰韦恩钢厂用比例为１：５的水模型试验研究了循环脱气器的主要设计特点。研究的结果表明，只要将真空罐上升管（提升气体）氢气喷咀的数目从６个增加到１０个，并把连通管的内直径从０．５ｍ增加到０．５５ｍ，就能提高脱气装置的性能。由此可见用一个改进的真空罐，可以将成品钢中的平均含碳量从２１ｐｐｍ降到１５．４ｐｐｍ，且使处理时间缩短２ｍｉｎ。此外，还探讨了脱气器的操作效果与熔化深度、喷咀的浸入深度三者之间的关系和在操作期间失效喷孔的影响。
Based on the need to improve process control of production of ultra-low carbon, interstitial-free atomic steel, the main design features of the recycle degasser were studied in a 1: 5 water model test at the Lanway mill in England. The results of the study showed that as long as the number of hydrogen nozzle risers (ascending gas) in the vacuum canister was increased from six to ten and the inner diameter of the communication pipe was increased from 0.5 m to 0.55 m, degassing Device performance. This shows that with an improved vacuum tank, the average carbon content of the finished steel can be reduced from 21 ppm to 15.4 ppm, and the processing time can be shortened by 2 minutes. In addition, the relationship between the operating effectiveness of the degasser and the depth of melting, the depth of immersion of the nozzle, and the effect of the failed orifice during operation were also explored.
