Abstract

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.
- pellet containing carbon,
- strength after being reduced and cooled,
- reduction at high temperature,
- smelting reduction
