【摘要】 在 １２７３～１５７３ Ｋ条件下研究了不同煤种、木炭和石墨与不同种类矿石制成含碳球团 的还原速度；进而讨论了温度、配碳比（Ｃ／Ｏ）、挥发分含量等因素对含碳球团还原所需时间和 金属化率的影响．通过测定含碳球团还原冷却后的强度，对影响强度因素进行了分析．还原冷 却后的强度在温度 １２７３ Ｋ时较低，配入含挥发分较高的气煤，可以使还原冷却后的强度提高， 加快反应速度．更多还原

【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 1 273 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.更多还原
