Information × Registration Number 0214U007217, 0113U001755 , R & D reports Title The researches on the obtaining of chromic oxide refractories with usage of fused chromicoxide grainy material and issue of trial lots of products. popup.stage_title Head Kryvoruchko P., Registration Date 29-05-2014 Organization Public joint stock company "The Ukrainian research institute of refractories named after A.S.Berezhnoy" popup.description2 The research subject is chromic oxide refractories on basis fused and sintered chromic oxide grainy materials.The purpose of the work is determination of possibility of fused chromic oxide grainy material in place of sintered chromic oxide grainy material usage in chromic oxide technology.The research methods are chemical, petrographical, standard methods of determination of mass's moisture, apparent density, open porosity, water absorption, cold crushing strength and thermal shock resistance of refractories.Research for obtaining of chromic oxide refractories with usage of fused chromic oxide grainy material is carried out. It is established that chromic oxide refractories at making them with usage in charge compositions of fused chromic oxide grainy material in place of sintered chromic oxide grainy material, formed by semidry or vibrocasting methods and fired in reduce atmosphere on the indexes of properties correspond to demands of technical requirementsТУ У 23.2-00190503-374:2012 for ХСУ brand and ТУ У 26.2-00190503-340:2011 for ХСФС brand. In compliance with the contracts trial lots of high refractory products: chromic oxide thickened and alumina-zirconium-silicate are produced.Continue the work in the direction of future improvement of chromic oxide and alumina-zirconium-silicate refractories technologies and expansion of their application branches.
