Coal agglomeration in blast furnace injection coals [PDF]

open access: yes
In order to reduce expensive coke usage, blast furnace operators inject coal to replace a portion of the coke. However, the use of some injection coals can result in blast furnace instability and lowered permeability. This thesis is concerned with the

Comparison of Cupola Furnace and Blast Furnace Slags with Respect to Possibilities of Their Utilization [PDF]

open access: yesArchives of Metallurgy and Materials, 2018
Blast furnace and cupola furnace are furnace aggregates used for pig iron and cast iron production. Both furnace aggregates work on very similar principles: they use coke as the fuel, charge goes from the top to down, the gases flow against it, etc ...
