U.S. iron ore production was estimated to have increased in 2018 owing to increased steel-mill-capacity utilization and higher steel demand. Raw steel production increased to 86.6 million tons in 2018 from 81.6 million tons in 2017. But before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the ...

Iron Ore Sintering Process in Steel Manufacturing

Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous belt-fed furnace. Sinter feed composition control is important because the various sinter feed materials are not perfectly characterized and their chemical makeup varies within a batch and between batches.

Sinter plant - Wikipedia

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical ...
