Shape of the blast furnace simulated in the present study, positions of raceway and cohesive zone are shown in Fig. 3. The computational domain is a halfcut model of the blast furnace with 5775 m 3 of inner volume, and the cut plane was represented by a wall with no friction. The coke and the iron ore particles were charged from top of the ...

A full survey of the laboratory and blastfurnace tests on 2 types of acid pellets is given. From the laboratory tests out in an atmosphere containing hydrogen, it appears that type B, produced out of magnetitic ores, has a far better low temperature disintegration index and a lower reductibility index than type A, produced from a hematite/magnetite mixture.
