Our Technology – Tecnored

Whereas the iron ore agglomerates in a blast furnace are reduced by CO gas, the iron ore in a Tecnored furnace is reduced within a “self-reducing” briquette – a briquette composed of iron oxide fines and carbon (coal or bio-char) reductant. By combining fine particles of iron oxide and the reductant within the briquette both the surface area of the oxide in contact with reductant and ...

Effects of anthracite replacing coke breeze on iron ore ...

Anthracite coal as fuel for iron ore sintering is compared with coke breeze. Anthracite is lower in porosity, higher in density, and slower in combustion rate. With higher proportion of anthracite in fuel, permeability of sinter bed tends to decrease resulting in lower sinter productivity. Higher fuel rate with more replacement of coke breeze by anthracite is ascribed to the lower density of ...
