Relationship between sinter properties and iron ore ...

The resulting sinters were characterised by chemical analysis, degradation during reduction in the blast furnace (reduction degradation index test), cold strength (tumbler test), coke consumption and process productivity. Sinter quality was assessed in relation to the granulation index of the ore mixture.

Sintering - Eurotherm by Schneider Electric

Sinter Plant. The function of the Sinter Plant is to supply the blast furnaces with sinter, a combination of blended ores, fluxes and coke which is partially 'cooked' or sintered. In this form, the materials combine efficiently in the blast furnace and allow for more consistent and controllable iron manufacture.

Blast furnace - Wikipedia

Blast furnaces used in the ISP have a more intense operation than standard lead blast furnaces, with higher air blast rates per m 2 of hearth area and a higher coke consumption. [58] Zinc production with the ISP is more expensive than with electrolytic zinc plants, so several smelters operating this technology have closed in recent years. [59]

What is the purpose of limestone in a blast furnace? - Quora

Limestone is the reducing agent, without limestone the iron ore i.e Fe2O3 will never get reduced to Pig iron i.e Fe .. "calcination" should be lesser inside the blast furnace to reduce the coke rate that's why sinter is being used nowadays, as in sintering process limestone is calcinised outside the furnace which reduces the coke rate by 5–8%.
