CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING

CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING R. P. Bhagat INTRODUCTION The process of sinter making originated from a need to make use of fines generated in mines and in ore benefiCiation plants. With the development of sintering technology, a sintering plant has become a tremendous success for providing a phenomenal increase in

Theory and Practice of Sintering of Iron ore – IspatGuru

Granulation is of basic importance for the sintering of iron ore, as good sinter bed permeability largely determines the rate at which the process progresses and hence the productivity of the sinter plant. The granulation of the sinter mix is generally carried out in a rotary drum prior to the sintering process, for several minutes with the

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

Iron Ore Sinter an overview | ScienceDirect Topics

The effect of iron ore characteristics on sintering is mainly through their impact on the granulation and densification processes. With the rapid change in iron ore supplies and composition, steel mills now have to adjust the composition of the ore mixture to their sinter plants more frequently than ever before. Hence, different scales of test

Iron ore sinter is produced from fine-grained ore in order to provide a direct charge to the blast furnace. During the sinter production process fine sinter is produced that is not acceptable as feedstock for the blast furnace. This fine material is screened off and returned to the sinter plant to be recycled. The production of these

Iron ore sinter materials are an important feedstock material for the steel industry. Since fines cannot be used in conventional blast furnaces because they impair the upward gas flow, they are agglomerated in sinter plants, Gosh & Chatterjee [1].
