EVOLUTION OF SCHEMES OF HEAT EXCHANGE IN A BLAST FURNACE
Bibliographic record
Abstract
The development of schemes of heat exchange in a blast furnace was considered with the improvement of the blast furnace smelting technology. It was noted that for the estimation of the thermal state of blast furnace as a control object it is expedient to divide it into two thermal zones, upper and bottom. The interface between them is in the top of the mixed recovery between the level of the beginning of the carbon gasifi cation of coke and the horizon, below which iron oxides are directly reduced. Upper slow heat exchange section in terms of heat exchange is reserve height providing better thermal and regenerative operation of the furnace. The bottom section of slow heat exchange should not be used as a reserve for improvement of thermal and reduction work of the blast furnace. It is shown that the presence of two zones of intense heat exchange in the present conditions of smelting of various types of iron ore using the combined blowing of high parameters is a prerequisite for the stability of the course of the blast furnace process and effi ciency of smelting.

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.
