Head Ustichenko V., Registration Date 22-02-2007 Organization The open joint stock company " The Ukrainian research institute of refractories named A.S.Berezhnoy" popup.description2 The subject of investigation is fused corundum from alumina and fused spinel from alumina and periclase. The purpose of the work - field supervision on fused corundum production and the receipt of fused spinel from the mix of alumina and fused periclase. Methods of research are chemical, petrographic, physical-mechanic. Field supervision on fused corundum production using electric arc furnace of pilot production of the institute is carried out. The melting analysis is carried out. Fused corundum of appropriate quality is received, namely: Al2O3 mass fraction amounts 99,7 %, Fe2O3- 0,07%.Technological instruction TI is designed and authorized. High-quality spinel with the following factors is produced: mass fraction: Al2O3- 83,9-84,3; MgO- 13,5-14,8; Fe2O3- 0,19-0,30%; open porosity 8,2-8,8 %. Work should be continued towards field supervision on production of fused corundum, mullite and spinel using electric arc furnace of pilot production Product Description popup.authors popup.nrat_date 2020-04-02 Close
