  • Lime in the Steel Industry | Graymont

    Lime is used to convert iron into ''pig iron''. In the blast furnace, finely ground or granular limestone (with a low sulfur and alkali content) is used together with finely ground lime to convert ore into pig iron. The pig iron is later processed into steel. Lime is used as a fluxing agent in electric arc furnaces and basic oxygen furnaces.

  • Why is limestone used in the desulfurization process?

    The limestone used for cleaning the flue gases is continuously added to the absorber sump to ensure that the cleaning capacity of the absorber remains constant. By blowing air into the absorber sump, gypsum is formed from the calcium sulphite and is removed from the process as a component of the slurry.

  • Understanding Limestone in Cement| Concrete Construction Magazine

    The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement. As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash. The cement might have a reduced water demand, and the coarser cement gradation
