Abstract
The sintering performance of Canada iron concentrate and metallurgical performance of sinter product was studied, the physic-chemical properties was investigated. The results show that the sintering indexes and metallurgical performance of sinter product both get some worse with the mixing rate of concentrate increasing from 24% to 42%. The permeability resistance of sinter bed increases from 857 Pa to 1 150 Pa,the vertical sintering speed drops to 18.38 mm/min from21.87 mm/min, the productivity declines from 1.14 t/(m2·h)to 0.93 t/(m2·h),the tumble index falls to 64.13% from67.47%, the anthracite solid fuel consumptions increases to 70.42 kg/tfrom 62.46 kg/t, meanwhile, the reduction index(RI)and the reduction degradation index RDI3.15 mmfor sinter product drops from 82.31% and 70.71% to 78.76% and 64.41%,respectively. This kind of concentrate was bad for granulating of mixture because of its major mineral-specularite and martite whose mineral surface has poor hydrophilicity-and unreasonable size composition, meanwhile, it is hard to generate enough liquid during sintering due to its dense and smooth surface and poor sintering capability-its softening temperature is more than 1 450 ℃. Therefore, poor granulating performance of Canadian concentrate leads to worse layer permeability then cause poor sintering performance, while high softening temperature results in the tumble index decreases when the mixing rate of concentrate increases.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
