Reducing Dephosphorization of SiMn Alloy Melt and Suppression of Phosphine (PH3) Gas Emission
Bibliographic record
Abstract
The dephosphorization (de-P) efficiency of SiMn alloy melt using CaO-CaF2 flux was measured at 1823 K under a strongly reducing atmosphere.De-P efficiency increased by increasing the CaO content up to CaO saturation point in the CaO-CaF2 flux at 1823 K, indicating that the phosphorus was removed from the SiMn melt by the reducing refining mechanism.When the Vee ratio (= CaO/SiO2) of the reducing de-P slags is greater than about 1.35, the lime and dicalcium silicate phases precipitated during solidification, resulting in an increase in the emission rate of PH3 gas due to an increase in the reaction area.However, when the Vee ratio of the slags is lower than about 1.35, the fluorite, cristobalite, and wollastonite phases appeared from the phase diagram, resulting in less amount of PH3 emission during cooling because the reaction between Ca3P2 and H2O was restricted to the surface of bulk slag.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
