“精料”是高炉强化冶炼的首要条件,其中提高烧结矿的品位是最为重要的。如何提高烧结矿的品位?一方面靠提高铁精矿粉的品位,另一方面靠提高铁精矿粉的配入量。在西钢现有的条件下,提高铁精矿粉的自身品位可调节因素十分有限,因此主要可挖潜的因素是提高铁精矿粉的配入量,即通过减少其它物料的配入量来相对地达到这个目的。 “Concentrate ” is the primary condition for blast furnace smelting, of which the improvement of sinter grade is the most important. How to improve the quality of sinter? On the one hand by improving the quality of iron ore concentrate powder, on the other hand by increasing the amount of iron concentrate powder. Under the existing conditions of XISCO, there are only a few factors that can be adjusted to improve the grade of iron ore concentrate. Therefore, the main potential for tapping iron ore concentrate is to increase the amount of iron ore concentrate to be dosed, that is, by reducing the amount of other materials Relatively achieve this goal.
