Abstract

Attention focuses on the possibility of automating systems for determining the postreactive strength CSR and reactivity CRI of coke pieces (≥20 mm) in a gaseous medium at 1100°C, with subsequent abrasion testing in a drum. Methods of controlling the coke testing are investigated. Current methods of automation and measurements are analyzed and rated. Promising approaches are outlined. The structure of a practical automation system corresponding to State Standards GOST 32248–2013 and GOST R 54250–2023 (ISO 18894:2018) is described.
