Description

The purpose of this paper is to clarify the influence of self produced gas on the reduction of pellets containing solid carbon materials. The changes of the state in the firing of the pellets were investigated by chemical analysis. gas chromatography, microscopic observation, and X-ray microprobe analyzer.<BR>The following, results were obtained.<BR>1) When the self produced gas reacted effectively in the firing of pellets, the green pellet containing 20% carbon materials was reduced to highly metallized state.<BR>2) The content of solid carbon materials and the gas volume of atmosphere in the beginning of the firing had be chosen to appropriate value.<BR>3) Maximum CO gas concentrations of 72, 73, and 98% were obtained by the pellets containing coke of 10.0, 12.3, and 20.0% respectively.<BR>4) In the case of the pellet containing charcoal, it was almost the same as in the case of coke's pellet described above, but concentration of CO gas was markedly increased in the temperature range from 700 to 1 000°C. It is noted that charcoal's pellets indicated good reduction degree in the range of low temperature, compared with coke's pellets.<BR>5) As the charcoal contents of pellet were increased, however, the compression strength become lower and the significant behavior of reduction at low temperature did not appear clearly.
