Mechanical Strength of Extrusion Briquettes (Brex) for Blast-Furnace and Ferroalloy Production: I. Dependence of the Strength Properties of Extrusion Briquettes on the Binder

摘要

The efficiency of preliminary homogenization of a briquetted charge using bentonite is shown. The dynamics of increasing the strength of commercial extrusion briquettes (brex) during storage under natural conditions is studied. A combined cement-bentonite binder is used to reveal a new effect of local maximum of the cold strength of brex at the third day of hardening, which is accompanied by a change in the character of its fracture.
