抄録

For the examination of stirring effect in the in-bath smelting reduction process, influence of stirring on the reduction rate of chrome ore was studied. The experiments were mainly carried out using a ten-ton test converter with oxygen top-blowing, nitrogen side-blowing and nitrogen bottom-blowing. After five tons of chrome ore were fed with coke and lime on five tons of molten iron, the stirring effect was examined by changing the gas blowing conditions.<BR>Main conclusions are as follows:<BR>(1) The change in the reduction rate caused by the change in the blowing conditions corresponds with the change in the stirring power for the slag layer.<BR>(2) The nitrogen side-blowing has nearly the same effect on the slag stirring as the nitrogen bottom-blowing has, when the blowing rate is the same.<BR>(3) The nitrogen side-blowing is suitable for the intensive stirring of slag, which contributes to enhancing the reduction rate of chrome ore.
