Ore-rich ironmaking can greatly improve the utilization coefficient and economic benefits of blast furnaces.

Iron ore contains high silica content, which means sending waste into the blast furnace. Not only does it take up space in the blast furnace, but in order to remove silica, a larger proportion of limestone, a slagging flux, must be invested. , the slagging reaction is still an endothermic reaction that consumes heat. Although blast furnace slag has utilization value, it is better to reduce the amount generated.

In order to improve the efficiency of the blast furnace, it is no longer just the use of rich ore. If the grade of the iron ore entering the furnace is not enough, it must be beneficiated first, and then the flux limestone should be used to support the sinter, in order to reduce such problems as Impurities like silica enter the furnace.
