The fuel and flux of amount, add in suitable water, through mixing and making material that a series of physical occur on agglomerating plant after pelletizing
Variation is learned, sintering is blocking, and the next step is carried out so as to be sent to blast furnace.
In order to reduce the coke ratio of blast furnace ironmaking and smelting cost, requirement of the blast furnace to sinter is often that high intensity and height are gone back
Originality.In sintering circuit, generally require sinter that there is higher intensity, high finished product rate, the relatively low rate of return mine and relatively low
Fuel consumption.The sinter of high intensity and high reproducibility consumes less coke in blast furnace ironmaking process, so as to reduce dioxy
Change the discharge of carbon.In the long run consider, carbon dioxide discharge-reduction is required one of bottleneck as restriction development of iron ＆ steel industry.According to
