Read OnRotary hearth furnace smelting reduction technology is to make the pelletizing ball which after ingredients, mixing, pelletizing and dried process be added to an annular rotatable hearth furnace and a rotary hearth furnace, rotating under the temperature of about 1350 ℃, the iron ore is carbon reduction.When iron ore fines of more than 69% of grade, using a rotary …
Read Oncokemaking and iron ore preparation are described in Chapter 3. CO 2abatement from the different iron production routes, namely blast furnaces (BFs), direct reduction processes (which produce DRI) and the smelting reduction processes (which eliminate the need for coking and iron ore sinter plants) are covered in the following three chapters.
Read Onproducing reduced iron from iron ore fines and non coking-coal.Note 2) 2.1 FASTMETR process In the FASTMET process, iron ore fines and pulverized coal are mixed and consolidated into pellets or briquettes and then fed into a rotary hearth furnace (RHF) in one or two layers. The pellets/briquettes are heated rapidly to max.
Read OnThe rotary hearth furnace (RHF) has been tried to pro-duce iron nugget directly from iron ore with coal which is regarded as the new iron-making technology (ITMK3).12) Therefore, a similar process was proposed to prepare ferron-ickel alloy directly with the rotary hearth furnace in this study. 2.
