| Summary: | In order to improve the energy utilization of rotary hearth furnace (RHF),
some methods were raised to solve the problem. Through changing the inlet
angle of the nozzle, a higher and more uniform temperature field can be got.
Thus, the burden in the furnace can be heated to the reduction temperature in
a relatively shorter time. By using multilayer pellets technology, the energy
can be utilized as much as possible. However, the top layer pellets would be
reoxidized when the middle and bottom layer pellets were reduced. The average
metallization of the reduced pellets get the maximum value at 25 min, which
is consistent with the reality operation. |
