sinter used in blast furnace

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 properties of the ingredients. The purpose of sinter are to be used converting iron into steel.

Agglomeration of Return Fines of Sinter for Blast Furnace

and used as raw materials for the blast furnace, the perme-ability in blast furnace is not deteriorated. Thus, an agglom-eration method for return fines of sinter by a cold process should be studied. Various non-fired agglomeration methods for use of these agglomerates as a raw material for the blast furnace have been studied since the 1970s.
