Sintered Dolomite is using high quality dolomite as mateial, sinteted by extra high temperature rotary kiln. It is characterized by high chemical purity, good degree of sintering, great resistance to slag and hydration. It's indeed ideal matetial of high class magnesia-carbon brick, magnesia-dolomite brick, ramming mix, etc.
The iron ore used presents a low MgO content (0.01%) and a high Al2O3 content (2.99%). It was seen that raising the MgO content in the sinter, from 1.4 to 2.6%, increased the FeO content and decreased productivity and the RI, RDI and TI indices. 2.1.4.
Low Iron Dolomite is extensively used in an iron and steel plant in various processes. Our Low iron Dolomite is high in Demand by Steel and Iron Industries and by others who requied low iron content dolomite with high purity. Dolomite is used as a slag former, slag modifier and as a refractory material. Home > hard rock screen vibrating > good quality dolomite iron ore s. metallurgical appli ion of dolomite.

In iron and steel Industry, limestone and dolomite are used both in ironmaking and steelmaking. Limestone and lime products are used as fluxing material both in ironmaking and in steelmaking. Basically limestone is used as a slag former, while dolomite is used as a slag former, slag modifier and as a refractory material. Dolomite and their Use in Iron and Steel
Reaction temperature of dolomite with calcium ferrite was lower than that with limonite iron ore about 155°C. Fluidity of bonding phase and strength of sinter using dolomite were lower than that using light burned dolomite and serpentine owing to the higher MgO content in the calcium ferrite and formation of secondary bonding phase.

Sponge iron manufacturing is highly sensitive to material characteristics that would help obtain the rated capacity and the desired product quality. To ascertain the suitability of our materials in a rotary kiln, Company has established a modern quality assurance facility that is responsible for conducting various tests in respect of the chemical and physical properties of our materials. Dolomite is a double carbonate of calium and magnesium, CaCO3, MgCO3. It is of sedimentary origin and is supposed to have been formed due to chemical action of sea-water containing high percentage of magnesia, on limestone. Theoretically, dolomite contains: CaCO3 - 54.35% MgCO3 - 45.65% In other words, it contains: CaO - 30.4% MgO - 21.7% CO2 47.9% In nature, considerable variations in the composition of dolomite relating to lime and magnesia percentages are found. When the percentage of CaCO3 increases by 10% or more over the theoretical composition, the mineral is termed 'calcitic dolomite', 'high-calcium dolomite' or 'lime-dolomite'. With the decrease in percentage of MgCO3, it is called 'dolomitic limestone'. With the variations of MgCO3 between 5 to 10%, it is called 'magnesian limestone', and upto 5% MgCO3 or less it is taken to be limestone for all purposes in trade and commercial parlance. Dolomite usually contains impurities, chiefly silica, alumina and Iron Oxide. For comm See full list on cargohandbook.com Dolomite is chiefly used as refractory, ramming, and fettling material in steel melting shop, and as fluxing material in blast furnace operation in secondary steel and ferromanganese manufacture. To a lesser extent it is used in the glass industry especially in sheet-glass manufacture. It also finds use in the manufacture of mineral wool. In England, dolomite has become a useful source for the production of magnesite by reacting calcined dolomite with sea-water. The UK is meeting nearly 50% of her magnesite requirements by this method. Dolomite is also a good source of magnesium metal. The magnesium metal is extracted from dolomite by the well-known fero-silicon process. Dolomite decomposes completely above 900ºC. The product resulting from this relatively low-temperature calcination is highly porous and reactive and is known as 'calcinated dolomite'. Dolomite is sometimes used both in the and calcined form as refractory material for hearth maintenance and for banking door in op See full list on cargohandbook.com Dolomite is a light yellow/brown coloured mineral stone which is very hard and compact. Dolomite may sometimes, incorrectly, be used to describe a material consisting of the oxides of calcium and magnesium (dolomite quicklime). Usually shipped in bulk and to be trimmed in accordance with the relevant provisions as required in the IMSBC Code. No special requirements with regard to stowage, weather precautions or ventilation. See full list on cargohandbook.com There are no special hazards. This cargo is non-combustible or has a low fire-risk. Consult the IMSBC Code for further particulars. See full list on cargohandbook.com The process of iron making is the reduction of iron ore to produce iron. Iron ore normally contain gangue materials such asSiO2, Al2O3 along with S and P. Removal of these impurities is done by combining the gangue materials with CaO and / or MgO to form slag which consists of low melting point complex compounds such as calcium silicate, calcium aluminate etc. CaO and MgO is charged along with other materials in the form of lime stone and dolomite or it is charged through sinter where
(iii) Good quality limestone and dolomite is available at a distance of about 200 km. (iv) Water and power requirements are met by the Tungabhadra hydel project located at a distance of about 36 km from the plant. Another steel plant at Paradwip is fast coming up. 10.
The mineral dolomite has hardness on the Mohs scale of 3.5 to 4 and a specific gravity of 2.8 to 2.9. The colour of mineral can be colourless, white, pink, green, gray, brown or black. Its streak is white. Its luster is vitreous or pearly.
Dolomite Crusher Dolomite Mining Dolomite Mines Dolomite . Coarse and medium crushing mainly used to process high quality Dolomite mine with dense blocks patterns. Fine crushing is needed when meet complex.
The basic materials for the production of sponge iron are iron ore, non-coking coal and dolomite. Sizing of the materials also play vital role in sponge iron manufacturing process. The required size of Iron ore, MPS (Mean particle size) , its physical properties like T.I., A.I. & chemical properties like Fe (T), LOI, gangue content In Sponge Iron Process , two types of coal are being used such as feed coal and injection coal.
Dolomite has been found as a useful support to limestone in removing sulphur from the iron ore. It also reduces the viscosity of the slag, thus chemical reactions in the furnace. For the steel melting shop the total insolubles below 4% are preferred. The silica content should be as low as possible, in no case above 2% being tolerated.
