decrease coke rate about 7% for each 10% of iron charged into the blast furnace as metallic iron, as indicated in Fig. 4.8) The solid circles added to the picture represent the fuel rate decrease calculated from the results of the present study. More recently blast furnaces in Canada, Western Europe Fig. 2.

DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and …

Method for making reduced iron using blast furnace sludge . An object of the present invention is to provide a method for making reduced iron whereby breaking of agglomerates containing blast furnace sludge into pieces and/or fines is avoided inside the furnace reduced iron products of high metallization degrees can be produced at high …

In many integrated steel plants, conventional BF-BOF furnaces use iron ore to produce steel, but more and more plants, particularly greenfield factories, are looking to make the direct reduced iron (DRI) and/or hot briquetted iron (HBI) by hydrogen reduction process and then melting them in the EAF.
