PROCESS OF MAKING BINDERLESS BRIQUET FROM STEELWORKS DUSTS

To produce smeltable briquets, steel-works dusts containing more that 15% metallic iron are heated in an indirectly heated rotary kiln to a briquetting temperature in excess of 500 DEG C. under an atmosphere which is inert to the metallic iron. The heated dusts are briquetted in the briquetting roll...

description	To produce smeltable briquets, steel-works dusts containing more that 15% metallic iron are heated in an indirectly heated rotary kiln to a briquetting temperature in excess of 500 DEG C. under an atmosphere which is inert to the metallic iron. The heated dusts are briquetted in the briquetting roll press under an inert atmosphere and under a roll pressure from 60 to 150 kN/cm roll width. The hot briquets are separated from the fines under an inert atmosphere and are air-cooled to a temperature below 130 DEG C. The fines are recycled to the rotary kiln.
