摘要: Silicon-oxygen equilibria in an Fe-0.003 ~ 27 mass pct Si alloy equilibrium with the CaO-SiO2 slags were studied temperature range of 1823 to 1923 K using a lime crucible. At same time, nitrogen distribution ratios, LN, between slag and metal measured, from these results reported values for activities SiO2, nitride capacities, % MathType!MTEF!2!1!+-% feaafiart1ev1aaatCvAUfKttLearuqr1ngBPrgarmWu51MyVXgatC% vAUfeBSjuyZL2yd9gzLbvyNv2CaeHbd9wDYLwzYbItLDharyavP1wz% ZbItLDhis9wBH5garqqtubsr4rNCHbGeaGqiVy0df9qqqrpepC0xbb% L8F4rqqrFfpeea0xe9Lq-Jc9vqaqpepm0xbba9pwe9Q8fs0-yqaqpe% pae9pg0FirpepeKkFr0xfr-xfr-xb9adbaqaaeGaciGaaiaabeqaam% aaeaqbaaGcbaaceiGaa83qamaaBaaaleaaiqaacaGFobWaaWbaaWqa% beaacaGFZaGaeyOeI0caaaWcbeaaaaa!3DDE! $$C_{N^{3 - } $$ , defined by (mass N). aaeaqbaaGcbaWaaSGbaeaacqWGqbaudaqhaaWcbaacbaGae83ta80a% aSbaaWqaaGabaiaa+jdaaeqaaaWcbaWaaSGbaeaacaGFZaaabaGaa4% hnaaaaaaaakeaacqWGqbaudaqhaaWcbaGae8Nta40aaSbaaWqaaiaa% +jdaaeqaaaWcbaWaaSGbaeaacaGFXaaabaGaa4Nmaaaaaaaaaaaa!441C! $${{P_{O_2 }^{{3 \mathord{\left/ {\vphantom {3 4}} \right. \kern-\nulldelimiterspace} {{P_{O_2 {P_{N_2 }^{{1 {1 2}} }}} }}$$ evaluated. It was found that LN decreased, whereas those for increased increase temperature. Activities SiO2 determined and obtained previous gas-slag experiments. These compared results.
