  • Effect of MgO Injection on Smelting in a Blast Furnace .

    It is noteworthy that the MgO content that the BF needs has been confirmed. If MgO is injected into the furnace with pulverized coal, the MgO content of the burden will decrease. Therefore, testing for different MgO contents of the burden in a high-temperature furnace will reveal the effect of MgO on the softening-melting properties of the burden.

  • Sinter plant - Wikipedia

    Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical .
