Abstract

A method is developed for manufacturing briquettes based on fine ferroalloy screenings providing sufficient mechanical strength and suitability for transportation. A batch of briquettes is manufactured from ferroalloy screenings for steel deoxidation. Ferroalloy briquette composition is studied in a scanning electron microscope. It is shown that a briquette consists of fine ferroalloy particles and pure silicon bonded by sodium silicate with various additives. Ferroalloy briquettes are tested for medium-carbon steel deoxidation in a steel-pouring ladle. Silicon assimilation from ferroalloy briquettes is 65% on average.
