During the production of iron by blast furnace (BF) route, dolomite is added either in the process of sintering or as a direct feed in the blast furnace. Raw dolomite is normally used for this addition. Dolomite addition is made during ironmaking for obtaining desired percentage of MgO in the BF slag.

Portland Cement (CEM I 42.5R) was replaced with dolomite up to 40% and blast-furnace slag up to 20%. Hydration heat, setting times, soundness and micro-structures of paste samples and compressive strength and length change of mortar samples were measured. As a result of experimental studies, dolomite used instead of cement caused up to 1.75mm expansion. The results are in accordance

furnace is used to make steel, stainless steels, ferroalloys, and special alloys, whereas ferromanganese is often made in blast fur- naces. Fluxes are used in all of these processes, and either limestone or lime is the major flux component with some dolomite, dolomitic lime, silica, alumina, and fluorspar being used. In ironmaking, the

Dolomite for use as flux in steel metallurgy should be hard, compact and fine-grained so that it can stand the burden of the batch in the blast furnace as well as the basic steel convertor. It should not be crystalline, i.e., it should not have a saccharoidal texture which gives fritting effect in the furnace. Impurities as low as possible are preferred. It should be free from phosphorous and

In ironmaking, limestone and dolomite are used in the production of sinter, pellets, and directly in blast furnace as fluxing materials. In case of steelmaking limestone and dolomite are used as lime or calcined dolomite both in the primary steelmaking (basic oxygen furnace, electric arc furnace), and in the secondary steel making processes.

The use of pure oxygen at high flow rates results in such fast oxidation of the elements contained in blast-furnace iron that only about 20 minutes are required per heat—i.e., to refine one charge. Converters vary in size. Steel - Steel - Basic oxygen steelmaking: More than half the world's steel is produced in the basic oxygen process (BOP), which uses pure oxygen to convert a charge of
