DIRECT REDUCTION OF IRON OXIDE-CONTAINING MATERIAL IN A ROTARY KILN |
摘要 |
<p>In the operation of the rotary kiln provided at its charging end with a central burner, solid reducing agents having a high content of volatile constituents are used and the charge and the gas atmosphere are conducted in cocurrent streams. To avoid a high heat load per unit of volume in the heating-up zone and yet to increase the heating-up rate, a solid carbonaceous reducing agent having a high content of volatile constituents is charged together with the iron oxide-containing material into the charging end of the rotary kiln, oxygen-containing gases are blown through nozzle blocks into the free gas space and into the charge in the heating-up zone, and oxygen-containing gases are blown through nozzle blocks into the free kiln space in the reducing zone.</p> |
