limestone in sinter production


Sintering | Eurotherm by Schneider Electric

Two important properties of sinter are basicity, which is controlled by the amount of limestone, and strength, which is controlled by coke content. The sinter is now suitable for use in the blast furnace. Conveyors transport the material to the blast furnace stock house, where it is added to other materials to form the blast furnace burden.

Sinter production - Praxis Engineering

Sinter production is one of processes of metallurgic production during which concentrated ore (or upgraded ore) sinters due to thermal processes and flux materials (usually crushed limestone) which are called sinter cake and serve as ready material for blast-furnace smelting. Additives and high temperature increase the content of iron in the sinter up to the required value.

Blast furnace - Wikipedia

2021. 2. 9. · Blast furnaces of Třinec Iron and Steel Works, Czech Republic. Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide, having a stronger affinity for the oxygen in iron ore than iron does, reduces the iron to its elemental form. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore
