Abstract

Abstract Excellent blast-furnace performance is observed when using screened sinter that is free of fines, with the alternation of tuyeres of normal and enlarged diameter. If the total mechanical energy of the combined blast at the tuyere mouth and the total mechanical energy of the blast-furnace gas increase in these conditions, the combustion zone becomes longer and the blast-furnace gas penetrates further toward the furnace axis. In that case, the benefits of the high-quality raw materials may be maximized.
