摘要: 在1273~1573 K條件下研究了不同煤種、木炭和石墨與不同種類礦石制成含碳球團的還原速度;進而討論了溫度、配碳比(C/O)、揮發分含量等因素對含碳球團還原所需時間和金屬化率的影響.通過測定含碳球團還原冷卻后的強度,對影響強度因素進行了分析.還原冷卻后的強度在溫度1273 K時較低,配入含揮發分較高的氣煤,可以使還原冷卻后的強度提高,加快反應速度.

Abstract: The reduction experiment of the pellets containing carbon, which consist of different kinds of iron ore and coal (including graphite and charcoal), was carbon out. The effect of temperature, rate of carbon and volatility etc. on the reduction time and metallization of the pellets has been discussed. The strength of the reduced and cooled pellets was measured and the influence of the factors was analysed. The strength of pellets at temperature 1273 K is low. When the gas coal of high volatility is added, the pellet is becoming to be reduced quickly and its strength is increased.
