An alternative to traditional ironore sinter phase

The pellet plant using the grate kiln technology is used to agglomerate and indurate iron ore fines into pellets while the sinter making enables us to agglomerate iron ore fines into a coarse product ie the sinter Hard and semihard coking coal is heated in the coke oven facility which consists of two batteries containing 48 ovens each Sinter is the primary feed material for making iron in a blast furnace According to the US Environmental Protection Agency the sintering process converts finesized raw materials including iron ore coke breeze limestone mill scale and flue dust into an agglomerated product sinter of suitable size for charging into the blast furnace Online Elemental Analysis of Sinter FAQs Sinter is the primary feed material for making iron and steel in a blast furnace To ensure a highquality product iron and steel manufacturers must start with a highquality sinter based on a proper selection of raw materials Online Elemental Analyzers are used for measuring and controlling
