William Davenport, in Blast Furnace Ironmaking, 2020. 54.4.5.5 Free Swelling Index (ISO 4698) The free swelling test determines the volume increase of iron ore pellets during reduction. When pellets were first introduced, a swelling tendency led to damage to the BF stack, poor permeability to gas flow, and irregular burden descent.

Iron ore also differs in physical form. Fines require sintering (agglomeration into crude pellets) prior to use in the blast furnace. Lump ore can bypass this process and be charged directly into the furnace, as can pellets, and both command an associated price premium.

2017-12-20 Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration ...

Blast furnaces produce iron by exposing iron ore, iron pellets, and sinter to high temperatures and carbon monoxide, a reducing agent. Coke is the primary fuel, although it is often augmented by injected auxiliary fuels. Preheated air from the hot-blast stoves is also injected into the furnace through the tuyeres.

2019-4-15 The blast furnace-based process uses sinter, pellets, lump ore and coke. All the inputs are charged to the top of the furnace, and heated to remove oxygen fromthe iron ore and produce the hot metal. The direct reduction process uses pellets, lump ore, and natural gas (or low quality coke) to reduce the iron ore. Pellets and lump ore are heated ...
