The high pressure metallurgy technology has promoted the development of smelting special steel. In this paper the characteristic of high pressure metallurgy technology and the devel- opment and application of smelting high nitrogen steel were reviewed. Combined with the theory of thermodynamics and kinetics for refining high nitrogen steel under high pressure and bottom blowing, the numerical simulation and physical simulation of refining process were conducted. The factors affecting nitrogen content in steel, including refining pressure and casting pressure, were analyzed. On self-made high temperature and high pressure reaction kettle, multi-factor experiments for refining and casting high nitrogen steel were carried out in laboratory, and the technical parameters of high pressure metallurgy for smelting qualified high nitrogen steel were ob- tained.
