Various carbon contents in the MgO C refractory were studied with respect to the oxidation resistance and the wetting behavior with slag The bulk density apparent porosity cold crushing
·Resin bonded black refractory exhibits crushing strength near to 500 kg/cm 2 at 300 °C which is much higher compared to conventional oxide based refractory bricks at this temperature The strength behaviour predominately depends on the bonding in preference grain size and pore content Dolomite Refractory Dolomite refractory is
·A method of preparation of multi impregnated pitch bonded Egyptian dolomite refractory brick for ladle furnace is described Brick samples were prepared from blend of calcined dolomite mineral and coal tar pitch The blend was hot mixed and pressed under a compression force up to 151 MPa Green bricks were baked for 2 h at temperatures up to 1000 °C
·has some detrimental eects on the refractory materials while a small amount of it is known to be a good source of tri calcium silicate which is the most stabilized form of dolomite refractory The low content of SiO 2 and Fe 2 O 3 in the dolomite deposit makes it suitable to be classied as low uxing oxides which possess a high crushing
2 ·Dolomite is used as ornamental stone and raw materials to manufacture cement and magnesium oxide for refractories [6] Limestone and dolomite constitute a group of raw materials commonly referred as carbonate rocks [7] Figure 2 Shows the relationship between Cold Crushing Strength and appreciable dolomite contents in the Blends Cold
·As the dolomite content increases in the clay dolomite mixture the silica as well as the potassium and sodium oxide contents decrease Therefore the decrease in the cold crushing strength of the samples with increase in dolomite content is as a result of the decrease in silica and alkali contents as the dolomite content increases
·Corundum brick a refractory structure with a single phase polycrystalline α alumina more than 99 wt % Al 2 O 3 Magnesite refractories at least contain 85 wt % magnesium oxide Dolomite refractories usually contain less than impurities and greater than % CaO MgO 2 Based on the chemical behavior refractories are classified
·The suitability of Oreke dolomite in Kwara State Nigeria as a raw material for the manufacturing of refractories was investigated The Oreke dolomite samples were mingled with feldspar clay and quartz to form a blend The fifteen 15 Blend samples were moulded and analyzed for their chemical physical and mechanical properties The characterization was
·Dolomite base refractories have advantages such as high refractoriness potential to produce pure steel molten high alkaline corrosion resistance and economical for consumers
Sintered dolomite is a key material used in the production of dolomite refractories which are essential components in various high temperature industrial processes The manufacturing of sintered dolomite involves the heating and compaction of dolomite a naturally occurring mineral composed primarily of calcium and magnesium carbonates
