Abstract

fetched live from OpenAlex

For a successful stainless steelmaking process, it is necessary to reduce Cr oxide in slag, using ferrosilicon alloy, as quickly as possible. The effects of particle size on the melting rate of ferrosilicon alloy were investigated by monitoring melting behavior of ferrosilicon alloys both on stainless steel melt and on the slag using a video camera. The reduction experiment using an induction furnace of 50‐kg capacity was also carried out. The experimental results indicated that the smaller the particle size, the shorter the melting time, and it is shorter on steel melt than on slag. It was found that the reduction rate is controlled by the melting rate at the initial stage of reaction, but after the initial stage, the transfer of chromium oxide controls the overall rate.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
