Granulation of the excess hot metal is a process that deals with these issues and produces a by-product - Granulated Pig Iron (GPI) - that can readily be used internally, for example as BOF coolant, or sold to third parties as feedstock for electric arc furnaces, cupolas and induction furnaces.
Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace.When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non-metallic product called blast furnace slag.

In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel. ... There can, however, be considerable variability in the physical properties of blast furnace slag, depending on the iron production process. For example, ... Granulated Blast Furnace Slag.
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.

Properties and Uses of Iron and Steel Slag MF 182-6 NATIONAL SLAG ASSOCIATION Page 5 Granulated blast-furnace slag is produced by quickly quenching (chilling) molten slag to produce a glassy, granular product. The most common process is quenching with water, but air or a combination of air and water may be used.
Granulation plays a critical role in iron ore sintering process. It influences not only the green bed permeability before ignition, but also the high temperature reactions, such as fuel combustion, 1,2) primary sinter melt formation 3,4) during sintering.
mixture first goes through a granulation process. In this process the iron ore fines, coke breeze, limestone and return sinter are mixed with water and tumbled in a rotary drum. ... iron ore (50 mass per cent Thabazimbi iron ore, 50 mass per cent Sishen iron ore) with fluxes not sized
[en] Imaging and understanding of iron ore granulation using X-ray microtomography. Evrard M., Contreras R., Pirard E. Most iron ores cannot be directly fed into blast furnaces because their particle size distribution will negatively impact the blast furnace permeability and hence the overall efficiency of the ore reduction process.
Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.
Granulated Beds effect on Sinter Properties. The two objectives of this area of research are; to understand the key properties of sinter that control quality parameters such as strength and reducibility; and to understand how sinter quality can be maximized by modifying process conditions and / or iron ore blends, while maintaining productivity and minimising operating cost.
