摘要：
The processing method for introducing an ultrasonic wave probe directly inserted into the molten steel was used. Effect of ultrasonic and argon-blowing on the nitrogen content in low carbon steel was carried out. The results showed that with the ultrasonic treatment separately, the nitrogen content in the molten steel reduced, but the removal rate was relatively lower with about 3.13 similar to 9.04 %. Using the argon-blowing agitation separately, the removal rate of nitrogen in the steel was relatively higher with about 6.89 similar to 32.68 %. With the increase of argon flow rate and prolong of the treatment time, the removal rate of nitrogen in the molten steel trended to increase at first, and then reduce.
