Abstract The sintering process is a thermal agglomeration process, and it is accompanied by chemical reactions. In this process, a mixture of iron ore fines, flux, and coal particles is heated to about 1300 °C1480 °C in a sinter bed. The strength and reducibility properties of iron ore sinter are obtained by liquid phase sintering.
