During the descent of material in the blast furnace shaft, the reduced iron picks up carbon from the coke, ... Hematite and magnetite are reduced to lower oxides. Indirect .Pelletizing - EPrintscommissioned in 1957 and includes 24 vertical shaft fur-naces.° In the 1950s, therefore, both vertical shaft kilns and moving grate machines were being developed and applied to the pelletizing of fine magnetite concentrates. Magne-tite concentrates are relatively easy to pelletize : the particles are granular (rather than plate-like) in shape,Detailed Modeling of the Direct Reduction of Iron .· As such, numerous iron ore shaft furnace models have been proposed in the literature. Initial studies addressed the reduction of a single pellet by H 2, CO, or H 2-CO mixtures [4,5,6,7,8,9]. Subsequent studies developed models that simulated the reduction zone of the shaft furnace in one dimension [10,11].development of shaft furnace technology in china .shaft furnace technology from china for iron ore pellet.

  1. Introduction to Iron ore Pellets and Pelletizing .Pellets have good reducibility since they have high porosity (25 % to 30 %). Normally pellets are reduced considerably faster than sinter as well as iron ore lumps. High porosity also helps in better metallization in DRI production. Pellets have a uniform size generally in a range of 8 mm -16 mm.Pelletizing Shaft Kiln | Pelletizing Shaft Kiln .The shaft furnace is countercurrent flow heat exchange vertical roasting equipment. The coal gas and air flow into combustion chamber through nozzles, ... The green pellets in shaft furnace form drying, preheating, roasting, soaking, cooling work zones during continuous declining process.AIR FLOW CONTROL IN SHAFT FURNACES - .· In a method of indurating pellet like material which comprises flowing the material downwardly in a vertical shaft furnace and causing heat exchange gas to flow upwardly through said furnace relative to said material, the improvement comprising heating a predetermined percentage of said heat exchange gas prior to introduction into said furnace, introducing a part of said fixed .

  2. Iron Ore Pelletizing Process: An Overview | .· Further development was performed to bring the idea to reality. In 1943, E. W. Davies and co-workers demonstrated the process using an experimental shaft furnace. Commercial operation started in the 1950s in Sweden using vertical-shaft-kilns for firing the pellets. Plant capacities were between 10,000 and 60,000 tons/year .Thermal Analysis In The Study Of The Firing .At Port Latta in Tasmania, Savage River Mines operates vertical shaft furnaces for the firing of pelletised magnetite concentrates. At times the temperature profile of the furnace has changed markedly, necessitating the- burning of greater quantities of fuel to maintain good pellet quality.
