Shaped refractory products for the cement industry

1 Shaped refractory products for the cement industryREFRATECHNIK22 Shaped arfctoyuasac ymsniInnovative refractory products and lining systems The use of alternative fuels has also taken on a new significance. Keeping pace with this technology requires suitable refractory products and lining systems: the conditions inside the kiln are a determining factor of its service life. To meet the globally increasing demand for cement , energy saving firing systems with high specific output have been developed in the industrialized countries and introduced throughout the world. One of the primary results of these developments is the precalciner kiln with a short rotary kiln section. 33 Shaped arfctoyuasac ymsniChrome ore-free basic bricksALMAG AFTOPMAG AFALMAG A1 TOPMAG A1 ALMAG 85 REFRAMAG AFBrick typemagnesia- fused spinelmagnesia- fused spinelmagnesia- fused spinelmagnesia- fused spinelmagnesia-spinelmagnesia-spinelChar acteristic component in %85 - 89 MgO84 - 88 MgO80 - 84 MgO77 - 81 MgO85 - 89 MgO82 - 87 MgOBulk density - - - - - - porosity %13 - 1515 - 1714 - 1615 - 1716 - 1815 - 17 Cold crushing strength N/mm2707065655065 Refractoriness under load Ctate> 1700> 1700> 1700> 1700> 1700> 1700> 1700> 1700> 1700> 1700> 1700> 1700 Pyrometric cone equivalent > 42> 42> 42> 42> 42> 42 Thermal expansion lin.
