The Effect of Time to Nitrogen Solubility in Steel with High Pressure and Bottom Blowing Nitrogen
Keyword(s):
The high nitrogen steel is alloy steel whose nitrogen content is more than solubility limit at atmospheric pressure[1]. Bottom-blowing high-pressure nitrogen smelting nitrogen steel has many advantages, in the paper, from the study of 18Mn18CrN,it can come to a conclusion that in the case of Temperature of 1853K, pressure of 1.0MPa, the bottom-blowing flow of 0.16m3 / h and temperature of 1873K, pressure of 1.4MPa, the bottom-blowing flow of 0.16m3 / h, With the bottom-blowing time of increased the nitrogen content in steel increases, but when the time is more the 10 minutes, the nitrogen content is saturated.
