Design and Analysis of Brick Lined Autoclaves for the Mining Industry
Bibliographic record
Abstract
This paper focuses on design optimization of brick-lined autoclaves to reduce wall thickness without compromising autoclave integrity. The use of acid resistant, brick lined, horizontal, autoclaves is common for hydrometallurgical processing within the mining industry. To prevent corrosion of the carbon steel pressure boundary, autoclaves are often lined with an acid proof flexible membrane and high nickel alloy overlay localized at nozzle areas. A brick lining protects the membrane against high temperature and abrasive damage that would result in corrosion of the carbon steel pressure boundary. Because of stringent out-of-roundness and deflection requirements, autoclave designers are faced with the challenge of choosing the proper thickness and layout of the autoclaves. Common practice for satisfying stringent requirements is to design much thicker autoclave than what is required to satisfy pressure and temperature conditions. This paper provides a methodology for the design that utilizes stiffening rings for controlling out-of-roundness that results in thinner and lighter autoclaves.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
