Mathematical modeling of natural gas injection in iron ore sintering
Iron ore sinter, an iron-bearing material for BF iron-making, is utilised worldwide. A schematic of the NG injection technology is presented in Fig. 1.First, after being ignited by a burner, the coke/coal fines combust downwards and the sintering process between iron ores and flux occurs owing to the presence of a high-temperature …

What is Sintering? (A Definitive Guide)
Sintering, which is also called 'frittage,' is the process of forming a solid mass of material through heat and pressure without melting to the point of liquefaction. This process involves the atoms in materials diffusing across the particle boundaries and fusing together into one piece. Sintering occurs naturally in mineral deposits, and ...
