The iron ore pellets contain a low amount of impurities and fluxes. Thus, the melting temperature of the pellet is controlled by the level of iron (pellet shell) carburisation [Citation 19]. However, the sinter contains a high amount of gangue (SiO 2 and Al 2 O 3) and fluxes (CaO and MgO) (Table 1), which certainly affects its melting behaviour.

Sponge Iron. Sponge iron, also known as direct-reduced iron (DRI), is a type of iron produced by reducing iron ore (typically in the form of pellets or lumps) using a reducing gas or solid reductant, such as coal.This reduction process occurs at a lower temperature compared to traditional iron smelting, resulting in a porous, sponge-like structure, hence …
The efficient operation of a blast furnace requires burden materials with high softening temperatures and a narrow softening–melting range. This leads to the formation of a thinner cohesive zone in the lower part of the furnace, which improves permeability. In this study, softening–melting tests were conducted on pellets with different levels of basicity, …
