Iron ore sintering - ScienceDirect

Sintering process for iron ore fines Like other sintering processes, iron ore sintering converts iron ore fines of often − 8 mm sizing into larger agglomerates, namely, sinter, between 5 and 50 mm particle size, which possess the physical and metallurgical characteristics and gas permeability required for efficient blast furnace operation.

Iron Ore Sintering: Raw Materials and Granulation

ABSTRACT Sintering is an agglomeration process that fuses iron ore fines, fluxes, recycled products, slag-forming elements and coke. The purpose of sintering is to obtain a product with suitable composition, quality and granulometry to be used as burden material in the blast furnace. This process is widely studied and researched in the iron and steelmaking …

A Novel Sintering Process for Porous Iron Ore Sintering with …

The present work proposes a novel process to sinter porous iron ore (porosity ~23–24%) with enhanced productivity and quality. The iron ore is pre-processed in the presence of calcined lime for the temporary closure of pores, which further prevents water absorption during the granulation process in drum in the presence of water. The calcined lime coated iron ore …

Iron ore sintering with charcoal - Taylor & Francis

The iron blast furnace is the most widely used and efficient producer of liquid iron; however, emissions from sintering and coking cause environmental pressure for the integrated steel works. The combustion of coke fines (breeze) during sintering contributes to greenhouse gases (e.g. carbon dioxide) and is a source of SO x and NO x emissions.
