| Abstract: | Reduction of enveloped pellets by roasting on the belt roaster in a direct reduction process with less investment and lower cost in producing blast furnace metalized pellets. This paper gives a theoretical analysis of the advantages with the pellets enveloped by iron-concentrate mixed with coal (plus additives),and introduces the authors'laboratory research as to the factors affecting on the strength and metalization rate of the metalized pellets,such as the amount of carbon-burden for the pellets, the kinds and doses of the additives in enveloping with iron concentrate,the maximum temperature,temperature raising speed,and atmosphere of reduction roasting. |
