摘要：

It is essential to clarify the equilibrium relations among nonmetallic inclusions of the MnO-SiO2-CrOx system and molten stainless steel in order to control non-metallic inclusions formed by the deoxidation of stainless steel with silicon. In the present study, the phase equilibria of the MnO-SiO2-CrOx system were measured by conducting the following experiments under controlled oxygen partial pressure, Po-2, at 1873 K: 1) Phase equilibria of the MnO-Cr2O3 binary system were measured for Po-2 = 2 x 10(-6) similar to 2 x 10(2) Pa. 2) Phase equilibria of the MnO-SiO2-CrOx ternary system were measured for Po-2 = 2 x 10(-6) Pa. Based on the results, the phase diagram of this ternary system was established under the condition of the Si-deoxidation process of stainless steel (Po-2 = 2 x 10(-6) Pa and T = 1873 K).
