Pellet-Sinter Composite Agglomerate (PSCA)of Iron Oxide Fines for Use in Blast Furnace

Making Pellet-Sinter Composite Agglomerate (P-SCA)

In Pellet-Sinter Composite Agglomerate (P-SCA), iron oxide pellets are embedded in to the sinter mass. P-SCA for use in blast furnace has been developed with Indian iron ore to utilize the micro-fines in sintering.

• It also uses steel plant's waste materials viz. LD sludge, mill scale etc (5-10%) with iron oxide microfines.
• The process yields a very good quality sinter even at the lower basicity that is usable in blast furnace.
• It increases the fines acceptability (30% above normal) improving permeability and decreases energy consumption (-20%) and flux consumption.
