The downward moving behavior of pellets in a 8 m2 pellet shaft furnace with an internal vertical air channel and a drying bed was studied by means of a visualized model 115 and a top model 11. The visualized model experiment shows that the downward movement of pellets can be regarded as plug flow approximately inside the furnace except for the lower region of cooling zone due to the ...

Drying and preheating processes of iron ore pellets in a. Induration drying and hardening of iron ore pellets is an energyintensive feed preparation step for both the blast furnace and direct reduction routes to iron It is commonly carried out by a gratekiln process A mathematical model of
process, which produces hot metal from iron ore and coal.35 Practically, it is a two-stage process that involves pre-reduction in a shaft furnace, followed by final reduction and separation in a melter gasifier MG. In this process, lump ore, pellet, flux and in some cases a certain amount of coke are charged from the top of the shaft furnace.
