The use of dolomite in blast furnaces. Dolomite is used in the production of iron because the amount of MgO as a slag can be prefixed by using a different amount of dolomite. During the filtration of iron by blast furnace method dolomite is either used in sintering method or directly inserted into the furnace.
Read MoreDolomite 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.
Read Moredolomite - dolomite - Uses: Dolomite is used as a source of magnesium metal and of magnesia (MgO), which is a constituent of refractory bricks. Dolostone is often used instead of limestone as an aggregate for both cement and bitumen mixes and also as a flux in blast furnaces. The use of dolostone as a flux has increased, especially since environmental contamination has become a widely heeded ...
Read MoreIn case of direct feed to blast furnace, lump dolomite (10 mm to 30 mm size) is used. In case of dolomite addition through sintering, these days calcined dolomite is alsodirectly being used. Use of calcined dolomite in the sintering process has the advantages of (i) Improvement in the binding characteristics of sinter mix, (ii) improvement in ...
Read MoreTurkey is rich in dolomite reserves and dolomite is abundantly found in several regions of the country. In this study, influence of blast-furnace slag (BFS) on expansion properties of dolomite was explored. Portland Cement (CEM I 42.5R) was replaced with dolomite up to 40% and blast-furnace …
Read MoreA blast furnace is a block that smelts ores, raw metals, iron and gold armor and tools, similar to a furnace, but at twice the rate. It also serves as an armorer's job site block. A blast furnace can be picked up by any pickaxe. If mined without a pickaxe, it does not drop anything. Blast furnaces drop their contents when broken. Blast furnaces can generate in any armorer house; these can be ...

Read Moresupplement local sources for use in fluxed pellets (Murray, 1988, personal communication). For many years in the United States, limestone and dolomite were transported to the steel producing centers for use in blast furnaces, lime plants, and sinter plants. The sinter plants were often
Read MoreIn 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.

Read MoreDolomite [CaCO3.MgCO3] is added in Blast Furnace as Fluxing agent. The main action of flux is to react with impurities (gangue) and take them into slag phase so that pure metal can left behind and can be seperated easily. Flux + Gangue ---> Slag.
