Use of Iron Ore Pellets in Blast Furnace Burden IspatGuru

Jun 13, 2014· Sinter, pellet and the calibrated lump ores are the three iron bearing metallics normally used in the blast furnace burden. Uses of all the three metallics in blast furnace burden can vary from zero to hundred percent with adjustment of the furnace parameters. These three metallics can be used in any combination of two metallics or three metallics.

Reduction of Iron Ore Pellets, Sinter, and Lump Ore under

Herein, the reducibility of the iron ore pellet, sinter, and lump ore in the BF shaft are focused on. The experiments are conducted isothermally with a blast furnace simulator (BFS) high‐temperature furnace at four different temperatures (700, 800, 900, and 1000 °C) for 300 min.

Sinter Plant an overview ScienceDirect Topics

Apr 02, 2010· Similar to sintering, pelletizing is another widely used process to agglomerate the iron ore. Sinter plants are usually located near the blast furnace plant, but pelletizing plants are often located near the mining site. Some works have both pelletizing and sintering plants at the smelter sites.

Sinter plant Wikipedia

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical
